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

I did read this whole thread. I know the engine very well thank you. in other words I am taking your shot to my intellectual stomach as an insult. Never the less let me rephrase my original post... FOR PEOPLE WHO HAVE A X6 110cc WHERE IS YOUR CODE LOCATED ON YOUR ENGINE???? There maybe that will be more descriptive and not cause further shots of insults.

HINT: Just ride... Don't insult <------ ;)
On the X6 x12 there is a white sticker on the stator cover, left side of bike when your sitting on it with the model # and bar code. also it will be engraved into the metal on the left side bottom right next to the kickstand.

Sorry hellboy i wasn't trying to poke fun at you sometimes i just can't help to be a smart A** I wasn't trying to insult you at all, i know how impatient you can be waiting for a new bike I'm on my 3rd bike and everytime i get a new one i try to find out as much info in advance as i can don't take it to heart i was just messin with ya a little, it will be very obvious when you get the bike like i said it's on the left side down low on the block and mine actually had a long white sticker on the top of the motor on the transmission case that had a real long number on it but the serial number was the very first part of the number on the sticker so check both places and let us know what it says also look at the number cast on the head. the cm3 number as there is probably also an e22 cast on the head. It will be interesting to see if you get a true 110cc!!:D by the way good luck with dh hell i got my chopper delivered by them and the whole back of the box was crushed and i had to get replacment parts for half the dang bike plus there were parts missing out of the box!!

I just got my X6 and looked at the serial... I have 1P50FMH. Now the 100cc is supposed to be 1P50FMG. I am supposed to have a 110cc. So whats the deal with this guys?

My engine # is 152FMH. There is no "p" in the engine #. What does this mean?


Thanks

My X12 is a manual 4 speed. Is that considered an auto trans? I would think not.
I thought FMG was a manual trans but I guess not.

there are three types of trannys
(auto) which has no gears its single speed
(semi - auto) which has gears but you dont use a clutch
(manul) has gears and you must use the clutch to shift
Reporting in w/ an '05 X6 110cc CVT. It does say 152FMH. Started her out w/ amsoil 0w-40 4 stroke synthetic oil. Just has that damn rattle, (which is not from the motor it seems to be the chain rubbing against the rear part of the frame as the engine spools it tends to vibrate around more. I am still trying to get the rear wheel perfectly aligned and tightened. The noise slows the tighter the chain is. Not too tight, but it has to be perfect.
were is the gorvernor find on pocket bikes

Once you get the rear wheel align, loosen your swing arm pivot bolt and watch that thing move about 1/4" in all directions. I aligned mine so the chain meshes properly, the wheel is off a good 1/4" to the front one.

For the chain noise, a cheap way to fix it (the way I did it) is took a small piece of nylon glued, it into that precision bend in the frame with JB Weld quickset. Delron is better, but I have some nylon. The chain still rubs, but it rubs quietly.

Sounds like a plan, will do that ASAP and report back. Thanks a lot for the tips.

Wow I'm new to all of it! thank you so much for this much needed info. I acquired a mini bike it think it it a X7 but I really have no idea. Is there any way to tell from the some what of a serial number on the frame? Thanks for the help and I will keep searching threads.
There are 2 and 4 stroke X7 bikes, so you need to know that first. Go online to pocketbikeparts, there in Florida, on ther main page they have photo icons of engines and bikes. Find one that is close to yours and click on it and see if the parts look like yours.
My scooter says TZH152FMH an under that is STAR01250761star on block. an the number on fins say 107cm3 what kind of motor do i have
You have a 110cc Honda-China clone engine, almost an exact copy. There are auto & semi auto transmissions and 4 speed manual w/ a lever clutch.
