mine is stamped hs152fmh..???
If you have a 110cc ( 107cc ) it will show 107CM3 on the bottom of the cylinder on the left or right, can't remember.
Those #'s dont compute.......Look exactly where the pic shows....if it says 48cm3;-thats 50cc but chances are its 70cc.....hey pocket bike forum I have a question ..i have a small engine that id like to put on my cag question is I don't the size of it im too stupid to know how to measure the bore but what I can tell you is that it has 2 rows of numbers on the block >A1E34F< underneath it says >*0103004660* (*= a star) can I tell the size of the engine from that set of numbers or no? please any help will make my day,

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.
How bout a 125ccOn 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
So I've read and keep hearing all types of different things this is on the bike I just gotThey 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.
Four stroke 4-speed semi-autoSo I've read and keep hearing all types of different things this is on the bike I just got

Okay and then I keep hearing PZ19. I just hate not having all the information even if it really doesn't mean anything it just kills me sometimes LOL thank youIt's just a Honda Z50 50cc 4 stroke clone but any pit bike engine will fit they all use the same bolt pattern
That's funny you say you would highly doubt the very markings I am actually looking at on the very motor I'm working on. I just got this basket case pit/ pocket bike in and literally the case is stamped 1P39FMB but the cylinder is stamped with 72CM³. Since it seems you have a hard time believing what your told here's a few pics just to prove what's being said.. now I'm trying to find out what I have so I was searching Google for information when I came across this thread. . This motor has no left side cover. Only 3 wire from the stator.a shifter lever but I don't see a clutch arm on the motor so I'm assuming it's an 70 cc Kickstart with automatic transmission. It appears to to be a 4 speed with neutral being all the way up and all the gears are shifting down, but I could be being mislead since it feels like 2 of the gears are slipping and sometimes grab but other times as I shift it slips. So if anyone has more information about what I have and am working with I'd greatly appreciate your knowledgeTo my knowledge there is more to finding out the cc of an engine then just measuring the bore. IE measureing the stroke also.
I highly doubt they would stamp a 70cc motor with 48cc.
This is what happens when the engines were made in China and assembled in Malaysia and they run out of some parts so they just slap some other parts on there lolThat's funny you say you would highly doubt the very markings I am actually looking at on the very motor I'm working on.
