If you have a 110cc ( 107cc ) it will show 107CM3 on the bottom of the cylinder on the left or right, can't remember.

Not all show 107cm3 for the 110cc........One of my engines had a cylinder casted with 108cm3..That was my older 2006 model X15 too.

They also had 49CM3 on cyld that were really 70cc on some 4 stroke pocket bikes. 107 or 108 either way there 110cc. My 1100 Honda was 1050cc, my 750 was 736cc, my 850cc chopper was 836cc, everyone rounds off the real size.

Holy smoke!

Finally i have found a thread regarding these type of engines.
I have a 1P39FMB and I was wondering if I could buy a cylinder kit for the 1p47fmf because they have the same stroke but im worried that the bolts wont fit...
I'm trying to get a little more juice out of my 49cc engine but i have tried everything like jetting, performance air intake, carburetor tuning, changing front sprocket with 1 tooth and checking for limitations but without luck.
could any of you please help me at least getting on a lead how I can get more power out of my engine? I also tried finding a performance camshaft but i only find GY6 camshafts which obviously are completely different.

You probably have a 50cc 4 stroke Honda clone engine. I believe the 50 and 70cc have a different bore and stroke. Online go to www. tboltusa .com, they have all the stuff. For around $400, they have a 88cc hp kit w/ high top piston, it will beat a stock 110cc. Email or call them about a cam, there totally cool people and have good prices. The case & mounting studs are the same on the 50 or 70cc.

50 and 70cc engines have the same stroke......90cc and 110cc engines have the same stroke but different from a 50/70cc....They all use the small valve E22 head

Alot of 70cc engines were labeled 48cm3 was a dishonest practice done by the chinese to get through customs faster and without scrutiny

For $225.00 free shipping you can get a 125cc kickstart only engine complete ready to bolt-in and go practically to slap right into the frame.....some modding will be required..........

The only way to truly know what is inside of those Chinese engines is to open them up and mic the piston

On the block you will find a number cast mine is on the left side under the transmission. This is on the block generally you can find a casting on the head as well but sometimes they miss with that before they ship the bikes.......
if the casting says:
1p39fmb = 49cc
1p47fmf = 70cc
1p47fmf = 90cc
1p50fmg = 100cc
1p52fmh = 110cc
hope this helps
How bout a 125cc
