Not sure since it doesn't say the size of the bore. 100cc in advertising means nothing. Lots of places call 80cc kits 90-100cc kits. It would actaully take a 55.5mm roughly to be 100cc, and I don't recall a kit above 54mm for these. My SunL just barely squeezed in a 50mm jug. Others have used as large as 52mm cylinders without modification, newer models apparently. So I would say plan on no, and hope for yes. lol
It's a good price regardless. I will say, that sucker will have some serious compression. Look at the size of the combustion chamber vs the size of the bore.

Thanks! If it's still there in a couple days I think I'll grab it.

Ask them what the bore is, because if it is a true 100cc there is no way it will fit without modifications, as claimed.

Cool. You definitely need a build thread. ;D I know you can handle the case modding. Can you deal with the reduced crank life of a big kit?

Cool. You definitely need a build thread. ;D I know you can handle the case modding. I hope I don't have to do any modding. The guy wrote me back that the O.D. is 53.22 mm's at the base so it shouldn't need any modding. He didn't tell me the I.D. so I'm not sure of the actual size in cc's. Prolly 80cc's How far reduced are you talking about?  For $50 i dont think you could go wrong at all! I don't know... Is there any specific defects I should be looking for when I go to pick it up? I might get the pipe too. $50 is a great price for that too. |

At 53.22mm OD I'm guessing it's a 50mm kit. My 50mm kit lasted 2,002 miles when in stalled with a new stock replacement crankshaft.

I should clarify what I said above, the kit actually didn't fail. The crank did, more specifically the big end bearing. It is said that Kymco cranks are better quality than typical Chinese. That may or may not mean they'll hold up to much more abuse from the big piston.
50mm makes a 139QMB 81.2889cc.
