Charging System Update (Motorized Bike)

[@Centar1964]

The magneto only has one winding (coil) as you have discovered with the white wire. Being a 2 pole A.C. generator it produces (lets say for arguments sake) a positive pulse on the down stroke which charges the CDI and a negative pulse on the up stroke which triggers the CDI...so there is no positive or negative wires on the magneto but a "phasing" if you connect it backwards the plug will still fire but 180 degrees out of phase so the engine will not run. You will not harm the CDI...if you try to absorb either the positive or negative cycles from the magneto (to power something else) it will either not charge the CDI or not trigger the CDI...either way no go...hope this helps understand whats going on with the china girl ignition system which is light years ahead of the old points type systems which were horrible...this system is basically maintenance free although no real adjustments which is both a good and a bad thing...

[@LAHover]

Simple and easy to understand. Thank you for pointing this out :)

[@matthewsherwood6617]

thank you thank you thank .its the problem i have 180 out , makes sense now why i ,ve got a spark but not firing

[@jakeford3359]

Best explanation you can get online!

[@GoingtoHecq]

This is a beautiful comment thank you.

[@newsnowpermianbasin8977]

Also the coil will rob spark from the magneto and the motor wants to run on the coil.

[@joebiggiotti5405]

Okay.., remember that cute silver box you first bought... that’s called a voltage rectifier and regulator. It converts AC to DC by rectifying it, and regulates the output to 13 volts DC, which will run your LED lights just fine without the battery. You have to add that, along with the new secondary coil you added. Leave the original wiring alone, add the 2nd coil, the two wires coming from it should feed the yellow or white whites which are INPUT on the regulator, leaving a red and black... guess what those lovely wires are for? :). No battery necessary.

Hey guys and girls. My name is Gary. I have been building and riding motorized bikes for several years now. The best thing that I have found to help with motor vibration transfers to the frame, is SIMPLY wrap the frame of the bike with electrical tape if mounting the motor directly to the frame... Or if you have to use a U-Bolt to mount an additional adapter plate to a frame use a snug fitting piece of rubber tubing (thick fuel line) to put the U-Bolt through like heat shrink.. the fuel line will allow you to tighten the mount securely to the frame and provide some vibration dampening safely.. that is you will have to periodically do checks on the integrity of any plastic or rubber parts on these bikes. Hope this helps someone. Have a fun and safe ride everyone.

[@whatsyurprob158]

What about Tuned mounts? I have 2 of them. I learned how to use the front one with the steel plate as the base, but the back one, I have no idea, 'yet'.. Btw, how some thin leather? It won't deteriorate as fast as tape. There's also the 1.25" Copper conduit Closed nipple trick >>>> that's the route I'm going. 🇺🇸

[@richdries3056]

This is actually the very first comment I ever made in my lifetime. I share the interest in these motorized bikes, but the best part of your videos is the honesty and your ability to admit when you aren't sure of something. I'm so sick of wasting my time attempting to re-create something that was from the beginning a sham from people just looking for likes and popularity without any reguard of the actual truth. For this reason you are awesome, and thank you.

[@russbilzing5348]

Shimano, Sturmey-Archer, SON, and many other companies have made front wheel hub generators. Sturmey-Archer alone goes back about 75 years. Unlike the constant drag of a small armature being turned by the wheel, there is no felt drag because the armature replaces the axle and the magnets rotate around it. It should be more than enough to keep your devices charged, whether the engine runs or not.

[@jeremiahacree8896]

the best way I,ve found is just bolting it right against the frame...I have rode the crap out of mine within reason of course and have yet to have anything vibrate loose, I do check it over about every other time I ride it just because its good practice... it seems to have a lot more issues with even a thin material between the engine and the frame, it also foams up the fuel in the bowl with the rubber mounts which starves the engine of fuel...that was frustrating, I just happened to read an obscure post in the depths of a motorbicycling.com forum about it and the rest is history...thanks for another upload man

[@ZeldaNumber17]

I have a small bike trailer I use for longer hauls and I have a charging system on the trailer. It has a Pully on the wheel and a rubber band that turns a small electric motor to charge 2 3.7v batteries in parallel. I use 5v leds and they work fine. The charging system gives out 4.4v at about 10mph so I can charge while I ride and have power at stops from the batteries. I’ve even installed a connector on the trailer so I can connect the bike. Meaning I can run the bike lights off the trailer batteries/charging system.

[@drivebrake]

Love your videos. I agree with you the rag joints are just fine. I did order a cheap hub adapter and broke three spokes and bent a few more. Although I had the bolts good and tight it just didn't hold. Then I noticed the inner surface of this cheap aluminum adapter wasn't quite smooth and flat. There was even a casting line right in the middle of the gripping surface. My solution was to hone it with a brake cylinder hone. My Cranbrook has the 1.5 inch hub so it's a bit better than a 1 inch for gripping area. Then I sanded the paint off the hub and added JB weld before torquing the bolts down. The hub and adapter are now (hopefully) married for life. Maybe that was a crazy thing to do but it's holding. Cheers Gord Schneider Vulcan Alberta Canada

[@stephenfhauk]

JB Weld is King! it will last longer than the rim.

[@Mr.Thermistor7228]

That's actually a great easy solution. What about instead of JB weld you use a piece of rubber like a piece of tube liner? I can't imagine it would lose grip, there is so much friction and clamping force there

[@shawnstone4949]

Thank you sir! Can’t get mine to run enough to find a leak… so this is our next fix…… hope it works. So tired of fighting this thing.. especially when it ran soooooo good at the beginning

[@isactrae9078]

Love to see a growing fanbase on your channel bud keep it up.

[@theassassin1789]

for vibration dampening i cut an old tube into strips and made it wrap around twice.. its thin and soft enough it still gets good grip on the bicycle but does help with the vibration some .. been running this for 4 years

[@theassassin1789]

also used 1 strip on the bar under the tank also. idk if helps any but i have never had a bolt break or leak and my bike has fell over a few times also

[@mickangio16]

I tried the rubber mounts when I first put my bike together with terrible results. It was so darn herky jerky at low speed acceleration that the left side of the frame broke loose from the rear wheel dropout. It has been welded and gusseted on both sides now and solid motor mounts installed. The motor runs pretty darn good and the bike goes much faster than I need it to or want to ride it to. It does easily over 30mph with a 44 tooth sprocket. I want better, smoother low speed rideability. I would like to put a 48 tooth sprocket on it but I can't remember who I bought the hub/sprocket from and don't know if the three bolt mounted sprockets are a standard uniform size pattern spacing. Anyway, It seems to have gotten a little herky jerky at low speed acceleration again so I checked motor mounts for loosening. I have the studs double nutted. I broke the locknuts loose and tightened the mounts- they do seem like they were a bit loose. I tightened the locknuts back up & took it for a ride. Still a bit jerky at low speed. I was thinking of making a steel shim to slip behind front motor mount strap in effort to better lock motor solid to frame thinking that maybe the motor mount strap has stretched or bent somewhat. Maybe using rubber as you suggested would work well. The bike is a 26" 1980s Schwinn cruiser style bike with the 80/66cc motor. I don't know why anyone wants to ride a BICYCLE over 30 mph! My bike's sweet cruising speed is faster than I need to go- probably 20-25 mph range. I'd like it to loaf along like that at a slower pace- probably 15-20 and be able to go much slower than that under the motor's power without chugging it. As a kid I have built mini bikes, go carts...as an adult have been a stock car racer, drag racer, and have owned motorcycles since I was 16 yrs old so I'm not afraid of speed- at least not in or on something that I feel comfortable at speed- haha. As much of a speed demon as I was as a kid I don't think I ever knew how fast 30-35 mph was on a bicycle until I put a motor on one! Everyone wants to go faster?! Maan. Be careful.

[@JustlilTwisted]

@@mickangio16 most of the jerking I have ever dealt with was at slow take off or as I let off the throttle and the cause of this was the chain being slightly loose and it bounces causing the jerk. I fixed this by adding a spring tensioner onto the motor and now it run smooth at any speed because it always keeps the chain tight. this is the one I use www.amazon.com/Spring-loaded-tensioner-Engine-Motorized/dp/B07NXX4PV4

[@mickangio16]

Gotcha. I also have the spring loaded chain tensioner but maybe could use a couple links taken out of chain for more tension.

[@mickangio16]

Thanks. I'm gonna take a couple links outta the chain & give that a try.

I looked into one of those 12V generator coils, but I was pretty skeptical about how much current it would generate. Major props for using a battery and rectifier/regulator though!

@@joshuamoon8442 generator goes to AC pins, out goes + and -. in other words, ac goes to the pins where both anode and cathode is connected, + goes out the pin where 2 cathodes are connected, - goes out where 2 anodes are connected. but don't even bother with this as you need a regulator too, because your "12v" generator is not 12v at all and you'll most likely fry everything if you don't know anything about electronics

[@MarkRidlen]

I just signed up for amazon affiliate links and it took me about 10 minutes. Super easy. You should consider it.

[@josephwilliams2917]

I have built many motorized bikes. My current is an 80cc (66cc) cranbrook. The reason you have a problem with your CDI killing the engine is because you need to separate your CDI and the charging generator. I have a 2 coil set up that the CDI runs off of one and the other coil provides the amps to run my headlights, taillights, blinkers, brake lights, and speedo light. its all LED. It also has a rectifier and it both powers everything on my bike and still enough left over to charge the battery at any speed above idle.

[@josenicolasaponte5232]

I just finished assembling a motorized bike and I was not able to turn it on, needing to check spark plug, magneto, carburetor and after testing everything I realized that I needed to open the throttle gas to the maximum and give the bike good pedaling velocity, only that way I was able to put it to work. Thank you for your advices.

[@MrNosajwhitey]

sounds like you have some good peeps in your comments

[@GoingtoHecq]

My own plans for an electric system involve a dedicated generator hooked up to the magneto, but only using the magneto physically cuz it isn't controlled by the clutch. I will hook up to it using basically the same way a pull start hooks up to it, just a lot more flush. Heck the greatest hope will be for an electric start. Also ac to DC converters are called rectifiers.

[@jeffreystroman2811]

Been watching a few of your vids, my first and only kit had an o ring on the carb, still haven't decided what bike I'm gonna use (have gathered a few over the years) the thing to consider is how a shorted coil can affect the magnetic flux lines developed from a rotating magnet. I.e. if you load down an alternator electrically the drag on whatever is spinning it increases. There is only so much magnetic flux to go around, the plates of the lamanite help to direct what flux is available, perhaps sucking them away from the bare bones rig that comes with the motor. Still have the motor clamped to a pipe on the bench. Don't be afraid to jig up a new rim, been doing it for 30 years and you just have to do it to get good, swapping a new rim is jumping in with both feet and there's no going back after that

[@race-all]

The thing with rubber engine mounts is that the rubber should be contained so that there is no room for much movement. The clamp needs to contain the rubber tightly. The clamp should have sides on it keeping the rubber under the clamp in it's place not letting it move. The rubber is only there to absorb vibration. Sides on the clamp will not let the rubber squish out the sides when tightening. It should make it compress, making it tighter. The hard part would be is welding sides on the clamp or machining the clamp so the rubber will fit into a pocket. I like doing 4 strokes because I get to make my own mounting points.

[@badbadbob1]

You need a battery to charge so the coil will not die from supply needed. Your CDI Should have a diode to stop the battery power from frying the magneto. But is sounds like the battery did fry the charging system.

[@LAHover]

I completely forgot about installing a diode... lol not sure how I over looked that, but I think you are 100% correct. Lucky the coil was still working when I took it off the bike. Good thing I did not keep running with it. Thanks for the info.

@@LAHover I have not hooked my battery up to the white wire yet. But I put in a 6v. rechargeable battery from an emergency light.

[@deividasleonavicius5071]

@@LAHover hi so the first thing i suggest would be to connect 12v incandescent bulb to the to see if it can power that then mesure voltage and current then try connecting ether more bulbs or more powerful one to see what is the maximum power you can draw from the coil. If the coil able to suply significant amount of power then you need a full brige rectifier to trurn ac into dc current the regulator you bought shuld have it inside together with voltage reguliator but its made to charge a battery that's why it doesn't have a capacitor so insted of geting nice dc voltage you get pulsating one. Never connect ac voltage directly to a devices that require dc you may permanently ruin then. If the regulator doesn't work out the biuld your own full bridge rectifier and get a dc to dc boost buck converter they are more efficient then linear regulators but only do that after you make sure your coil able to supply the power nesery but you still migth need a small battery to hellp supply power when engine is idling.

[@MOHCTPOXOD]

I connected an oscilloscope to the magneto, and discovered that the stock coil only produces around 1W of power. Based on the wiring diagram of the stock CDI I found on the Internet, only 1/2 of this power is used to power the ignition. The other half, could be potentially utilized using some electronic circuit. This electronic circuit, yet has to be developed. However, 0.5W is not much to power an LED. As for the auxiliary coil, its problem is that it messes up the magnetic field for the main coil because it locks the magnetic loop even though there is no physical contact between them. The gap is just too small. There is nothing you could have done to make this system work. It was a good decision to stop.

And a stator is a coil pack mounted next to the flywheel with two to three wires connected to a CDI that connects to the spark plug

[@devilsadvocate1338]

Thanks for the soldering tips man

[@LAHover]

No problem 👍

[@The1stHomosapien]

i have a standard 50cc china doll, wow such fun, i went on an adventure today, for 4+ hours! still has fuel in the tank! anyway, just wanted to say, i lowered the needle clip in the carb one notch, it definately runs better, faster and better, cooler, it was lean asf.

[@HiddenBlessingsHomestead]

I tried hooking up lights to mine but had the same problem

[@joshuayaddowmotorizedbicyc7708]

Where can I get exhaust gasket for my seeutek pk80 80cc

[@LAHover]

If your muffler uses bolts I recommend replacing them with studs to help prevent blowing out the gaskets. These should work, www.amazon.com/Flange-Gasket-Stroke-Motorized-Bicycle/dp/B075YWH6TK/ref=sr_1_4?crid=2N2Z2HSYAKIA0&dchild=1&keywords=motorized+bike+exhaust+gasket&qid=1600471675&sprefix=motorized+bike+exhaust+g%2Caps%2C196&sr=8-4

[@joshuayaddowmotorizedbicyc7708]

They are Allen bolts everything is stock i have the seeutek pk80 80cc

[@JoshuaAnother-messenger]

I was wondering what is wrong with my bike with 80cc two stroke China doll I have put about 350 miles on the motor now and out of the middle of nowhere I stopped getting spark I put new cdi new magneto and still it won't start does anyone please have a suggestion I have tried everything

[@codelicious6590]

Why not go 6v like vintage motorcycle?

[@LAHover]

Lazy, 12 volt stuff is just so cheap and easy to find :P

[@WalterKnox]

if you are soldering, the lead free stuff sucks. I guess it does not matter TOO much with wires and stuff, but when working on circuit boards and stuff where you want nice pretty joints, the good old leaded solder is so much better. a good quality flux paste or flux pen is also really helpful sometimes.

[@Chromie21]

U build drones too? Commercial or fpv??

[@LAHover]

Ya, freestyle drones for just messing around. I mostly use them to fly in firework shows :D ... it's a blast!

[@Chromie21]

LA Hover you should make a drone video compilation, sorta like the ones I’ve got on my channel

[@antrasix-beatsproductionho9813]

Isn’t there 3 wires white blue and black the white is your aux 12 v power supluy to your bat and lights etc: the blue is the cdi or coil wire black is common to both blue and white

[@LAHover]

Some have three (not all), but 10:00 shows that the white and blue are connected together.

[@michaelmullins2230]

I'm having issues with my engine cutting off when I come to a stop. the engine backfires, but in a odd way it usually makes a big popping sound like one to times, then it cuts out

[@bassjumpblues3631]

consider using a light generater to charge the battery. Just thinking it might work without the motor!

[@eduardorodriguez7689]

I used a AA powered lights and they turn off when the motor turns on. Help!!!

[@ericellquist7007]

If you have anything grounded to the handlebars, you need to put a jumper wire capable of carrying the load from the handlebars to the frame. The bearing race with its grease and the fact that it may be insulated from the frame by paint will not allow a reliable ground path.(the races are in the top and bottom of the vertical tube the fork stem passes through, as I'm sure you know; which is most likely painted.) . It is my contention that the kill switch (normally closed) opens up the circuit from the magneto to the CDI, stopping the flow of current to the CDi. This makes more sense to me than the idea that pushing the button somehow provides a direct short to ground, something that in most instances is to be avoided. It would be easy to test with an ohm meter. If you have landed one of those wires on the handle bars to cut down on clutter while assuming that the current would be carried from the handlebars to the frame as a ground path, that may be a part of your problem. This is just an educated guess, an example would be the ground strap from most gas powered ICE automobiles (as opposed to diesel). The rubber portion of the motor mounts prevent a ground path from the engine, and thus the spark plugs, for instance; to the frame to complete an ignition circuit. Not being able to see the circuitry, I can only guess where the fault lies.

[@LAHover]

Solid information. Although I ran ground wires from each device to the batter I would not have thought about the poor connection through the head set, Good to know. As for the kill switch it is a "push to close" circuit (short). The motor will still run with the kill switch wires unplugged.

[@Wisdom_Wisecracks]

I just installed the Bikeberry CDI ignition. It was recommended to add their Super Magneto for a bigger spark. Also available is a bigger magnet. I did not buy. I may later. I'm not a Sparky . But maybe that's the magneto for you.

[@user-kc2ru5xo4k]

The scenario that u referred to as 'engine flex' is commonly referred to by automotive mechanics as 'torque twist', in a high performance drag car application, this initial 'impact' or 'shock' can cause a lot of damage to many driveline components. Many people solve this problem by installing solid metal mounts and/or 'engine plates' - a steel or billet plate cnc-machined to the shape of the front mounting surface of the engine block, this is then sandwiched between the timing cover/water pump etc and the block itself, these components are also machined down in thickness to compensate for the thickness of this engine plate. I think this example I have provided from the automotive world tells us that we already have a head-start in our motorized bicycle application...

[@keithstone3263]

Try putting a rectifier (4-#4001 diodes ) on the red and black wires from the magneto ( blue and red ) don't connect a ground wire to the frame if you want the engine to stay running.

[@derrickcarroll4932]

Have you tried a wheel dynamo they use them on touring bikes to charge phones lights and stuff

[@LAHover]

Heck I never even knew about them. Thanks I'll go have a look.

[@NathyTheNetbook]

Your regulator should be a half wave rectifier use that in conjunction with the secondary coil and you'll have power.

[@guyxmas7519]

A great way to respoke a wheel completely without any stress about screwing up -- take the tire and tube off -- remove 1 spoke , replace it immediately with the new one. -- tight it to approximately to a what it was And repeat one spoke at the time And finally retrue the wheel ( shouldn't be too out of wack --

[@counter929]

Depending on how comfortable you are with modifications, You might be able to utilize a duel set of Magneto's and coils. Mounting them up in the coil area(would have to find a new way to seal that area) would allow for enough power for both the motor itself with a "stand-alone" system for the lights, horn, etc. It would still be ac current, but you might be able to find lights that would work off of ac current or like with LED lights they might have adapter bulbs for ac current. Hopefully this will help.

[@gordiepeck4364]

The coil puts of way more voltage then you think, and next to nothing for amps

[@ruhan1924]

Good job bro

[@dieselgeezer18]

Is this the engine with the hex bolts? I've heart these are better. If its not, how many problems have you encoutered? Im new to your channel and i enjoy your videos a lot!

[@LAHover]

This one has no hex bolts. I agree that the hex bolt motors are better. However this is a Seeutek, Seeutek motors have great reviews, and mine (now 3.5 years old) has never given me any issues.

[@GeorgiaRidgerunner]

maybe the generator coil is causing the ignition coil to ground out some way it hard for me to really know without being there to look at it

[@SpACeCruizeR2o3]

what is this Amazon place he keeps mentioning i haven ever heard of it LOL ....Replying fRom thE dArk AGes

[@williamhollie7817]

Try a gy6 regulator? It's designed for this... I've got several as they're cheap, so I may give it a try. L8R,. Bill

[@LAHover]

Oh thanks for the feedback. I'll take a look and give it a try.

[@travisraney4405]

Isolate the coit from grounding to the motor and run an independent ground to your electrical circuit from the coil

[@valentinmelendez8650]

LA Hover do you still want help with the charging system because I have the 12 volt set up but I never installed a Battery to it plus I've seen how you wired it on the video and it was Completely different from the way I did it You are my favorite person to watch when it comes to Motorized bicycle stuff and I just wanted to see if you still needed help with this because you haven't talked about it since this video

[@LAHover]

Thanks for the offer. I'm going to just stick with rechargeable light for the foreseeable future.

[@GooWorldOrder]

Hey there, could I get an explanation of how you achieved it? And no battery for you huh? I'm just getting into motorized bikes and I'm absolutely determined to set up a proper electrical system, but I can't decide if I want to go with a magneto system or try to set up a pulley driven alternator. But any tips from someone who's actually done it would be great, thanks!

[@julieogutierrez3246]

LA Hover, I like to heat your comments I think you say a lot educational information that I really appreciate, this is the 1st time I comment in the internet I started putting together electric bicycles just lie a hobby about 3 years ago, right at the same time the pandemic hit us I had build many electric bicycles, at one time family and friends come to my house and I was able to put 10 electric bicycles and we all jumped on the bicycles and went riding the streets of San Bernardino the City where I live, it was a lot of fun, after that satisfied experience I took all this bicycles a part and stored them, like to mention that I’m a certified welder and fabricator it is natural to me to build, rebuild, or even fabricate from scratch ether way is been an absolute experience and fabulous adventure in my life, since ten I been having a lot of fun, like I build one test and take a part again, also I had build my own battery packs, I been learning to do all this thanks to KZbin and the super inspirational people like you that make all this videos, without it I be nobody, but I’m getting ready to make a video or two of the last projects I’m working on, till then I will keep watching videos of wonderful people like you and all the KZbinrs that inspired me to make something out of nothing. Thank you all so much. Julieo

[@summerstorm3959]

Yeah I’d like to know how you hooked yours up as well

[@MattExzy]

I'm a bit late to the party - but the magneto coil would definitely be interacting with the generator coil through inductance - no physical connection required. I'm no electronics/electrician whiz either, but the two fields are probably acting to cancel each other out. Now... in theory... it should be totally possible to grab some voltage, but I feel like the DC-generating coil would need to be basically far away from the magneto coil. And even then, it would probably need rectification etc. It's why it's so tricky to understand how a car's alternator works - they seem simple enough, but they're deceivingly complex.

[@getsmart2594]

I watched your video and remembered I had a Dynamo on my Schwinn Stingray when I was a kid. It worked great and was relatively cheap. I looked them up and they are on amazon pretty cheap and with LED. both front and rear light. Under 20 buckerinos. Not bad. I was thinking if you ever have a problem with the motor, how do you transfer your magneto to another motor or a bike without the head ache. Well with the Dynamo its really easy and its contained on its own circuit. I understand if the Dyanamos / bike friction, light by STVZO certified from Germany. These are actually the best low friction, low noise and have been tested optically for the road. However they are not cheap. I am going to buy chepo. LOL ! - but if its to loud or has too much drag then I will see how much the motor bogs or if it affects the mpg and to see if it can even handle higher speeds. Keep up the great content :) Oh, absolutely loved the 4th ehem 5th of July video and those awesome bangers. Now just think you also ate some bangers too. In england thats what they call hot dogs. LOL !

[@michaelbrinks8089]

I was thinking of going the $25 Dynamo kit also & maybe modding it. Coz the removable rechargeable head/tail light kits sounds like a pain. I had a dynamo when I was a kid & remember it didn't cause very much drag. I was thinking of taping some NiCad batteries together & making a crude on board dynamo rechargeable system. Add an on/off switch & wire it so the lights can be ran straight off the battery pack or the generator. Then use the generator to either run the lights or to recharge the Nicad battery when riding in the day time. I have a $5 digital voltmeter laying around I can connect to the NiCad battery. Since the batteries are cheap, the charging doesn't have to 100% accurate. When the 6V battery bank voltage reads say 6.8V you know it's full charged. When it's down to say 6.2V you know it needs recharged. I think I have some old cell phone batteries laying around I could solder together to make a battery bank. They're lithium instead of NiCad but free so if I ruin em, no loss. Even if I don't get the rechargeable battery pack made to work. I think a decent dynamo kit would still be better than dicking around with a removable /rechargeable head/tail light kit. I wish someone would actually make a decent low priced motorized bike lighting kit. I'd buy the one in this video, if they figured out how to make it work & provided some instructions.

[@troygill9544]

Just a quick tip , Try get starting it Pull clutch in kick the pedal then drop the clutch I can do it takes practice. So much easier when working on it

[@teddysmith457]

Something to help me with oil fuel mix ratio if I quit doing it the way that 32 to 1 I think it’s just too rich in oil so I go to 40: 1

[@HakanMUSTAFAKEMALATATURK]

20:1 after a while 16:1 as i remember

[@FelekSta]

Nice 66cc with 49cc sticker ;)
