2016 Apollo 110cc Top-End Rebuild

[@garettbodel3002]

Great job explaining every thing. Haven't done a piston and ring job in 4 years needed a quick refresher thank you that was quick and precise and all the little knick-knacks that you need to look for a great job

[@KGRowlo]

Thanks! Working on motors is like riding a bike you never really forget sometimes just need a refresher👍Tried to make it quick and to the point with out all the boring BS! Thanks for the sub

Great video bruh, I've been looking for something like this. Only hoped that you did the piston rings part more in detail. Overall well done 👍

Nice like to see torque specs and if it needed to be locked up when tightening the sprocket so that the rotation wasn’t going backwards?

[@nickbaker7502]

Did u have oil leaking into exhaust ? Was that the reason of getting a new top end? That’s my issue on my sons atv smokes and took off exhaust from head and a few drops of oil came out

[@backyardmowerracing492]

I’m having trouble trying to find the right piston for my 125. Is it the 52.5 or the 54? Or what size was your piston

[@KGRowlo]

Do some searching on google to find that out, or measure old piston with a pair of calipers👌

[@evanknight3629]

125 is 54 110 is 52

[@AntonyMyrzak]

I didn’t catch if you said what clearance the exhaust side should be. Can you lmk??

[@spencer.h561]

I have a pit bike with a generic looking 110cc engine, are these kits universal or do I need to get a specific kit for this particular brand of engine, the engine looks pretty much the same as any Lifan or other 110.

[@KGRowlo]

Pretty universal 👌

[@josiahharness4848]

Ive watched this video about 10 times a day over the last week prepping for some top end work needed on mine. One thing I may have missed but on the new head did you have to do anything to the cam to adjust the timing? Thanks again for a great vid!

[@KGRowlo]

It’s been a while since I’ve done one, I usually check to see what position they are facing before I disassemble, but I believe the cam lobes should be facing down toward the piston when setting up the timing

[@josiahharness4848]

@@KGRowlo Thanks for the fast response man! Gave you a like and subscribe! Thanks for the content

[@aggeloskoumaris1586]

im not really familiar with this motors , but i presume its like a lifan right? you should most definetly at some point do a 53mm piston on one of these things , they come stock at 52,4 (at least the lifans do) and you would think that ,06 is like nothing , but flat pistons do really suck , thats why they feel slow from factory , even the 125's . Oh and it wont cost you anything , these kits are like 50 bucks for the bore up , and you can get away with using same head , also there are the big head caps and the small ones ( i dont know how they called ,hope it makes sense) big head caps (the one that covers the timing sprocket in it) means that you can also use a stage1/2/3/4/5 camshaft

[@KGRowlo]

Yeah all these little motors are pretty much the same! That’s good to know! Funny thing is I actually just sold this bike today😔BUT a new 125 will be entering the channel! And I’m sure I will be trying to make it faster! I’ll have to check out different sized pistons🙏

[@aggeloskoumaris1586]

@@KGRowlo they are kinda tricky motors and supposedly "weaker" from the 110 wich poroved itself bulletproof , the 125 can get biger cam (certainly) , i think that the 125 has 14mm piston pin , i made one back in the day but the strugle was real cause i couldnt fing big bore ups from a well know make i soon found out that the yamaha t135 pistons have 14mm pins so i went to the machine shop with a brand new piston (62mm)and the stock cylinder and made it work(used cnc flange to lower compression) . however the small crank is not known to hold big power and i f'ed it , the rod almost killed me LOL it went straight out of the casing , while disassembling it i found 2 crank pieces instead of 1 .Looking forward to the vids

Hi bro i have issue with atv 110cc, it burns oil, white smoke is coming from exhaust. Is that piston rings, since i replaced valve seals?

[@KGRowlo]

Sounds like it

Yo bro what’s up with the update on the bike? I just picked up a 2020 RFZ 150cc gonna need to rebuild the head to and 3/4 gear is stuck now got it super cheap.

[@KGRowlo]

I sold this a long time ago

[@mikefazzini9846]

Great video. I did this on my kids quad because of low compression (70psi). Leak down test, heard air in crankcase. Did piston/rings/gaskets (cylinder still has cross hatching and not gouged). Did compression test, still 70psi and still leaking air into crankcase. Ever had this issue or any ideas on what to look for? Thanks

[@KGRowlo]

You will hear a bit of air in crank case but you shouldn’t hear much…. Did you do dry test? Try holding throttle wide open while doing the compression test and see if that changes the psi result!

[@mikefazzini9846]

@@KGRowlo Yeah I did dry and wet. Both in and out of the bike. Engine is on my work bench right now. I did notice you have the silver edged piston ring up top and black one underneath that. Mine are switch (didn't have paperwork on what ring was what). And there were no markings on either ring. Could that be my issue? But still getting same readings as before? I'm losing my mind 😆

[@KGRowlo]

@@mikefazzini9846 🤷‍♂️idk man I would have to have the motor in front of me, I would swap the compression rings around… and if there are any letters stamped on them they always face up

No I meant intake, gotta suck air/fuel first before you can have a compression stroke

[@kennyB0990]

2018 DB-34. Curious as to why I have an issue in top-end. Bike sounds like it's bogging at top-end, yet this thing fires up one kick, damn near every single time. I have changed my Main Jets all the way from 92 to 140, every size in between, and have never been able to get it tuned to a point where it won't bog down on top-end. I have even adjusted needle both directions, checked spark plug. Any idea what is cause the bog at Top-End. Also checked Valve Clearance. Tried without Air-Filter off as well. Any idea, anyone, what my issue is. Nibbi 19 Carb.

[@KGRowlo]

Nibbi is kinda a pain in the butt carb to get right is what I’ve heard…. Try a Mikuni and try running like a 18-20 pilot and 110-120 main…. Thats what it sounds like to me

[@kennyB0990]

@@KGRowlo I think my pilot is at like a 32, it fires up amazing and idles great, hence why I never tried smaller. I think I will go that route, till I get correct Mikuni. Have one, but it hits my frame. I think it's rich, because smell, spark plug color and the feeling it gives, yet everyone keeps saying bigger jets. I thought maybe my float was too low maybe too high. So many variables, I'm going to be an expert by the time I'm done. 🤣🤣

[@KGRowlo]

@@kennyB0990 your pilot controls more mid throttle than anything, the notch on your slide dials the idle in along with the fuel/air screw and idle screw

[@wags9777]

Timing chain sprocket would have gone on easier if you'd loosen the tensioner

[@KGRowlo]

Agreed but i didn't really have a problem with it, just tight! But it saves having to take flywheel and stator off to get to the tensioner!
