100cc BIG BORE KIT INSTALL ON 50cc SCOOTER

[@mlgedits7204]

im not an expert by any means but i also like tinkering with my scooter and i think that your engine isnt getting enough fuel so try installing a bigger main jet in your carb

[@kaylabification]

yea i was about to say. a carb adjustment might be needed after the big bore

[@BewandTheBark]

I purchased the 150 cc carb with my 100cc BBK. Works great!

[@ryang3588]

If you take the flywheel cover off, there are little marks on the flywheel. one has a T next to it, you line that up with the arrow on the case and check to see if your timing chain circle is lined up with the top and you will know it's in top dead center.

[@FlamingsonsMotocross]

Correct That’s how I always got my bikes to Top Dead

[@rjuarez4913]

Also I always mark the chain to the cam with paint so when you reassemble there is no question you are dead on tooth for tooth on your timing. Even if you change your cam you can transfer the mark to your new cam.

[@rjuarez4913]

I also noticed if you push the cylinder down onto the new piston , you may move the timing , so supporting the piston from below is a must when forcing the new cylinder onto the new piston.

[@_james4766]

Re check the timing up jet the carb and adjust mixture and the intake valve should be 0.002" and exhaust should 0.004 "

[@davenotyerb4923]

You may have moved it away from TDC when you reinstalled the chain onto the cam. It only takes very little movement to throw off your timing.

[@dan1596]

I've done the 100cc bore kit on my ICEBEAR Maddog and I set the intake at .003 and the exhaust at .004 and it started right away. I first set it at .004 both top and bottom wouldn't start. As I said before I went to .003 on intake and it fired right up

[@ohdok733]

im thinking of big boring mine, any advice?

[@brandongoodrich4978]

The “where’d the 10 go?” Referring to the 10mm is too common 😂😂

[@cristichirtan3458]

You should upgrade the carb also...the jets i mean!✌

[@stevenhowie1135]

I got a question i did a 100cc big bore kit and 150cc carb with it idk if thats ok. What jets would i need cause i got a low throttle bog. Qmb139 engin. Also what size in diameter is the jet. Right now 103 main jet. And i think 31 or 33 idle jet.

[@marcuscook5145]

@@stevenhowie1135 If you over-carbed your engine, it kills low end torque, though you should have a pretty strong high end.

[@danielbargo8511]

Yes a jet swap is required and also valve adjustment after that iv built 8 of them

[@gmmelissaenergystaff-newbe3725]

I upgrade to 100cc big bore and works fine. Try using airbox with the air lines hooked up. Probably not getting enough air

[@BewandTheBark]

TDC is on the flywheel behind the shroud (plastic cover) it's marked just behind the magneto with a line that lines up with a spot on your block...never seen the screwdriver trick. Also you can check the valves.. .if they're loose just a CH chances are your TDC.

[@clubedarisada4638]

was wondering if after that you changed the displacement of 50cc to 100cc of the scooter if the connecting rod did it withstand the pot? because the pressure will be well may.

[@michaelarmajo4572]

The issue might be you moved your timing off with your chain check that one tooth may be off. The second issue is the amount of gas you are feeding it. Look at the Air Fuel Mixture Screw and adjust it for the sweet spot.

[@JoshuaFrascello]

Try .004 on the exhaust valve that's what I did to get mine going with the 100cc kit

[@rjuarez4913]

The piston wrist pin clips actually have an outside and inside. The middle portion you grab with your pliers should be installed so the circle of the clip is the only part that comes in contact with the pin. The middle portion actually is bent to one side, and that side should face outward or it will come in contact with the wrist pin first and can actually dislodge the clip if installed backwards!!! Got this info from a KZbin Harley mechanic.

[@Spitfireseven]

Your getting the same results we all get. Some bikes just won't start. The next video will be good!!

[@Donbscooters757]

I have to watch the timing part over n over to make sure i do it right next gi around for me

[@Donbscooters757]

I think that's where I messed up not paying attention to top dead center when taking it apart. Really stupid of me honestly

[@browilky9465]

Put your hand on the back of the carb and see if that does any good if not then redo the timming and the valves make sure it's getting spark , check the coil wire, cdi box, change the spark plug

[@nickmckenna5035]

So what was it the carb? I run a bbk 110 honda. Carb always gets ya when everything else is on point.

[@howardlangford8087]

When putting a big bore kit...you have to give it a break in a break-in period of at least 300 to 500 miles of no more then half throttle . If not going back and forth doing it over is what you will be doing. This also equal to 3 to 4 full tanks of fuel used .

[@96cr]

How much faster does the 100cc big bore make it go?

[@jesseburroughs8500]

Connor brewis how much are they usually?

[@lek2455]

Jesse Burroughs usually they go 35. the big bore lit makes it go 50-55 if you tune the cvt and get it pretty well dialed. good luck getting 60mph idk where that dude got that from. my 100cc big bore with racing cdi, big carb, tuned cvt, aftermarket variator, aftermarket clutch, and a bunch of other stuff only gets 50.

[@ncntollison1989]

When doing a 100cc big bore kit on a 50cc scooter you should always upgrade your carb. Clutch spring. And variator. Also upgrade to a stroker Crankshaft. You can go on eBay and get a stroker Crankshaft for $189.99. Strongly recommend doing this.

[@aarok9422]

SouthernSin89 what if i upgrad from 50cc to 70cc should i do the same as u said ?

[@DaxtonAnderson]

If you're going to spend $190 on a 50cc motor you might as well buy a predator 212 and figure out how to fit it. 212cc for $120.

[@StefGaming]

its better of course but theres no need, i have done this but then 80cc.. left everything stock even the main jet.. airfilter and exaust.. and it started right up after kicking 5 times

[@shredder_mang3211]

Can you please man a video just showing how to rewire a scooter? Like I noticed you have your main wires clipped here, I wanna do my harness like you have yours done but have no idea what any of the wires go to or how to do it 😭

[@Donbscooters757]

I tried this day before yesterday and failed because of a crank bearing. Due to ne not checking the motor before hand .. ny fault. And a bummer but im going to try again soon with another motor i have laying aroun lol this time ima fully check the engine before installing the 80cc head

Hey brother, a question, I have a 50cc scooter and I plan to put the 100cc kit on it, I would have to change the cylinder head-cylinder head, or I could use the same one.

[@almighty8836]

You can used the same head make sure you used the gaskets that come with the kit... a good set up is 47mm A9 cam #88 jet NCY coil and CDI rollers light weight parson 7.5g heavy parson go with 5.5 or 6.5g rollers intake .004 ex .005 Clutch stock works good with out over heat in the motor... get you about 49mph next to a car

[@tronixfix]

Did you watch to not move the crank shaft? Because if it rotated just a little bit your timing will be off.

[@jeffreyherrin8870]

Probably way late on this. But did u make sure it was at TDC on the compression stroke?

[@tdurbin593]

@@StefGaming it may start right up but if you are bringing in all that air and not giving it more fuel that is the definition if running lean. It WILL burn the engine down. It may not do it on startup or a day or a week from now but it will happen. Please do some research. Look up stoicionetric air fuel ratio. Even that us theoretical and is only for a perfect engine in perfect conditions if pressure and temperature in a perfect world. You always will have to run richer than that. It can burn pistons burn and warp valves and can cause detonation that can destroy every metal part inside the engine. The kits done right really bring these bikes to life. If you have a 200 dollar kits then plan on it costing at least 500 or more dollars to do things right. The kits don't come with all needed items. Without the necessary exhaust, a proper cdi that has an expanded timing curve and isn't limited, and the proper carburetor and jetting that kit you paid good money for and spent the time to put in will destroy itself from the inside out. They can be great, but they can be a real nightmare when they fail and you see all the internals ground to metal powder in the oil laying on the ground and have to call a wrecker or a friend to come get you and the bike because it failed. I didn't even touch the subject if the cvt and clutches. There is no cheap way out. You can pay in the beginning to do it right and it'll cost a little more or pay alot later when the engine burns down.
