Also, the bike is a 1975 kawasaki km100 but the engine it had loosely sitting in the frame is a 100cc bridgestone, didn't know they made shit other than rubber. Looked it up apparently it's from a bridgestone bs100. Anyone know anything about the market for it? It's frozen up right now but sitting with pb blaster in hopes of at least getting it to turn. No pics of it alone but here it is in the bike

4 stroke. They're ohc as far as I'm seeing. From 50 to 150cc are the most common

The engines you are referring to are all clones of the Honda horizontal style engine. Honda made this style starting in the 60s, even today the crf50 uses this style engine.

That is called a small shitty cheap chinese piece of garbage that will grenade itself within 20hrs of use

Have you had experience with this? I'd like both sides, a lot of people hold them pretty highly

GY6 engine i think

>>16651904
The gy6 looks like a scooter only engine. It's designed for the engine to be the swing arm. This engine isn't.

Are you asking what type of engine it is or are you asking for a specific manufacturer/model of what you have in your picture?

90% of the people on this board are complete retards so rest assured even seemingly coherent or reasonable answers are complete and utter nonsense

sub 50cc chinese pocket bikes use a simple 1 cyl 2 stroke engine. they are dirt cheap and i can assure you it's not the same as what Honda is using

the 110c+ use 4 stroke, also some dirt cheap

Honda 50.

AFAIK they are all Honda C90 ( less often CT90/C100/CT100/C110/CT110 ) clones.

Don't know the exact type / engine name, but looking for C90 clone will help locating one.

Lifan owner/operator here. No it won't. The Lifan copies of the Honda motor are license built and work just fine. I've used them for a few CT70 projects and yes, they work just fine.
