I found this site by accident when I was looking for info on bike frames for engines. I bought an old bike from a flea market and then I bought one of the miniature motorcycles with a 4 stroke 50cc with a 4 speed tranny and a centrifugal clutch which I decided to put the motor on the bicycle. I don't know about this bike build off, or if I could get it done by the deadline. I have to first get my welder fixed before I can modify the frame to accept the motor.
The miniature motorcycle is fun, but I can't legally drive it on the road. It is supposed to be able to go about 50mph as it is, (I haven't tried to see) With the tires being much taller on the bicycle I think it would go to fast to be safe if one wanted to go there. lol Anyway, glad to have found others that like the same hobby I do.
If anyone has already tried to do a build similar to this I would be happy to hear, and hopefully learn from their experience.

Ron, aka Neat Times is right, fundreamer1, and welcome to the motorized bicycle addiction / community, and to one of the greatest motorized bicycle forums in the world!!! JMO.

You should try reading up on Stretch Cruisers & Chopper builds, for info regarding the Chinese cloned Horizontal Honda 50cc 4-Stroke, Mini Trail 50, Monkey Bike 50, ATV / Dirtbike / Pitbike 50cc-110cc type engines.

You can find on craigslist an Schwinn Stingray OCC Chopper for really reasonable price $40.00 and up. The bike you are using is not practical for using that type of engine, you need a stretch cruiser or chopper bike to really make something happen with your build.

Here's the Links in Stretch Cruiser & Choppers forum I'd suggest for you to read:

These threads will answer many of your questions, as most of these builders who use Chinese cloned Lifan, Loncin, Hensim, Roketa, Horizontal Honda 50cc 4-Stroke, Mini Trail 50, Monkey Bike 50, ATV / Dirtbike / Pitbike 50cc-110cc type engines, have been there & done that with regards to this style or type of motorizing!

Peace Crazy Horse.
P.S. As for the chain size you can remove the rear cover on the engine where your drive sprocket is you should see the sprocket size & chain size stamped on the sprocket! see pic below of drive sprocket with chain size info etc etc..
