You should do a video of port and polishing the exhaust and intake port to a bigger intake and exhaust size since these engines are badly restricted of exhaust and air flow to promote better combustion in the combustion chamber while running and the moped i have like this runs much much better with a port and polished head with a unrestricted straight piped exhaust and putting bigger valve seats in the hemi type head that's pretty funny these engines have a very small hemi engine in these scooters and I think it's funny to say YEAH ITS GOT A HEMI

I believe when you bought the full kit , they include a H.O oil pump to deliver more oil to the bigger top end or so the say & u have a big enough pump to run a NYC oil cooler. So they say couldn't tell the stock oil pump from the extra in the kit . I'm not 💯 for sure nice clean big bore complete, I have to actually pull my motor for a big bore frame is smack in the way for 150 to a 180cc & 30mm carb get ya moving Fwd great vid !

hi im going into a engineering school. Im not a professional yet but i think you should lubricate the piston and its componets to avoid any internal damage at the first startups!

Great video, very informative and well shot, much better than many. I've watched over a dozen videos with different motors, different kits all to get an idea of what problems others run across. Generally, they are all similar. Anyway; None but one ever mentioned using assembly lube for re-installation. As cheap as that stuff is, I believe it is a must do step. Or at least use regular motor oil, (preferably heavy weight/thicker oil). I use a restaurant ketchup squeeze bottle and use straight 50W oil when I can't find my assembly lube. It sticks better. You should pre-oil the wrist pins, the rings and cylinder, the lifters, (both the pivot points & all contact points), the chain tensioner as well as chain and sprocket. Any metal to metal wear points. Then before you replace the plug, either hand turn or use a drill or the starter to turn over the motor several times to start the oil pumping through the engine before a hard start. Then no matter how well oiled, let it idle for a minute or two to help seat everything then a short test drive, (short, no over revving or speed test). Then change the oil. Any metal shavings need to be removed right away. One video did mention to get a magnetic oil drain plug, good idea with or without a rebuild. That is just my two cents worth; "An ounce of prevention is worth a pound or cure". This is just a suggestion for my knowledge. I would love either a video or at least information on what the best setup would be for different size rebuilds, like, this 100cc upgrade, the best clutch setup, lighter or heavier weights on the flywheel, best carb jet size or better yet carburetor to replace, what CDI to use, etc. etc. Thanks for the video, you did a great job.

Some tips: When attaching the piston, already put one of the clips in the piston before you slide it on the crank. Easier ;) And very important, lube the piston and cylinder with engine oil. Don’t slide it on just like that. Same when montaging the headbolts, lube them and make shure the threads are clean before you torque them.

@@Nthefastlane ah ok :) what weight rollers do you use in youre scooter? I got the 50mm kit as well with a 24mm carb and the head with larger ports and the performance camshaft. The scooter pulls well till about 25mph, flattens and starts pulling again at 30, maxes out at about 42mph. I got 6,5gr rollers and a performance exhaust with 27mm downpipe and a fake yoshimura muffler.

Did the same on my 2006 peace motorsports 50, previously bored it to 80cc and just recently went to 100cc and trust me on a50 with the small tires 65mph is almost to fast unless it's a nice smooth surface, I have to also be careful not to get caught speeding because in North Carolina anything over 50 cc and goes faster than 35 requires a motorcycle endorsement which I don't have, but anyways it really helped with the performance I also put a performance muffler and coil as well, down hill probably 70ish but i havnt had the balls to try it 😆. Tags and registration 24$ and 12$ a month insurance with Geico.

Whenever I've done a head job I always use some oil on the cams etc helps with the first start no cooling cover not a good thing.

You forgot to lube the piston and rings + cylinder! And i installed a 80cc cylinder today and used some oil in the cylinder and piston. No smoke at first start up ( without exhaust ofcourse )

right good video worked for me

Great video, Im looking at putting in a 80cc kit, so far I have the piston, rings, block and cam. Do I need to replace the carb or ignition system at all?? great videos mate very informative.

Another thing you want to do is use assembly lube on your wrist pin, inside the cylinder walls , and on your cam lobes and other various metal to metal contact points so installation is easier and you need some lubrication before the oil gets there in initial start up. Very important.

Hello, great video, and great explanation. Congrats! I have a baotian bt49qt with 139qma engine ( I assume it is the same engine as 139qmb) and it has lack of power and much blow-by at the cover vent. Where i live they don't sell bbk's, however they sell cylinder, piston and ring set for 80ccm, so if I go with that set would I have to change cam head and/or anything else like carburetor? Thanks

incredible and so nice motobike love lots your video .

Thanks!

Hey Brian D,First make sure you bolted the 2 Black ground wires to the valve cover..without those you will not have enough ground and the lights will be dim.

There are so many comments, questions and points. But this is like puttin lipstick on a dog. A peace sport firstly. And an 80cc on that model would do fine. It's very light. But mostly why are you making a how to on something you are not well versed in..... But it all boils down to, thanks for keeping local scooter mechanics busy! You help alot. And 5/16? There is no standard its all metric. All u need os 8 10 12 14 17. Sometimes a 13mm thats it

Good Stuff gy6

Quality video

wow THANK YOU !! WOW !!

The oil pump is a higher capacity pump, it flows more oil.. install it 100%. Bigger piston, bigger bore it will need more oil. Don't forget to lubricate the rocker arms,cam etc.. dont put them in dry

I had a couple of suggestions for doing this demo I would have taken the motor in gear trade out of the scooter and put it on a patch so that people will be able to see things more easily there's parts of your video to where you cannot see what's going on this would really help as a video for teaching people how to assemble this Bore Kit also I would suggest taking off the side cover and turning the crankshaft manually by using a socket and Ratchet this way if the person makes a mistake when installing the cam gear and chain where the timing is not right this way you will not Bend a valve just a precautionary measure because a lot of people have never put in a Big Bore Kit the cam sprocket is so tiny it would be really easy to be off a couple of notches and not even know it also is very important to show people how to make sure there crank is at top dead center and both valves are closed I hope the information I have talked about will help people and will help the man who made this video I think you did a really good job but these are some ideas that may help him make other videos in the future

thank you brother

Good work

you make me wanna upgrade my scooter!!! haha

Im getting that kit. But aint no way i wanna tackle that. I got a buddy for that. But i did put a clutch and variator yesterday. What a difference it made.

12:14 instead of using screwdriver to pry it out. a gentle tap with mallot helps. 23:40 apply a drop of oil before installing piston pin clips and piston ring and you won't need pliers to shove the clip in. 29:00 shims/guides are known by one more name. dowel pin.

You have to use different rocker arms because the original ones don't reach the valve correctly.

nice job

for the 90cc on a kymco super 8 I take the 50 head, that combination works fine also the 50cc camshaft, up there you have to go fit, experience say that, with this setup you get with tight running almost the 100km / h 80cc 86 nozzle 50cc head / 50cc camshaft, drive in at 50km / h then full throttle and do it in such a way to speed up and take off, giving a little to his thunder, so the cylinder is not lazy either.

The little bolts are 8mm yes a 5/16th will work if there not real tight but can srip them out just trying to help I enjoyed the video thanks

quick tip on those carbs use a small dremell cutting wheel to put a groove in the screw then unscrew with a flat screwdriver. doing it like this you can use the screws to reassemble.

Last time I did work on the engine on a "baotian" 4-stroke scooter, I actually removed the entire rear from the frame - was so much easier to work on it.

Nice

Awesome video and thank you for sharing!!!

Lucas assembly lube helps alot also

Great vid, btw what size jet did you end up using, did you have to change anything else in carb dept.? Thanks again!

man...that's a bunch of work. thanks for the vid! maybe i'll get brave enough some day and have enough time to do this.

you did not use any assembly lube or oil

Instead of squeezing the clip and possibly bending or distorting the clip, insert the clip the same way you did , but use a scribe into the same notch , but you can insert the scribe into the notch but outside the clip then pry the clip inward with the scribe. This way you are only affecting one portion of the clip.

nice one

thanks

Great video. Question though, did one of the new rocker arms not slide into place easily? For me, one fit perfectly, the other will not fit in between the two walls.

Anytime Don

Good advice about the rocker arms, however, just for trial and error, I tried to put the rocker arms the wrong way and found it’s not possible. The casing will not allow the cam shaft to fit. I did find it WAY easier to oil the cylinder before installing the piston.

Dont forget to lube the engine when mounting the kit with engineoil, to prevent drystart. thats a big problem if it fires without any oil lubricates the cilynder walls when new.

does this owrk on a ruckus just the bore size no other mods like the stretching

Awsome!! how much faster did it go after all the mods?

Thank you for your video. I have a question, I have a Lance Cali Classic 50cc , How could I change it to 100cc. Thank you.
