My friend has recently aquired a 91 yfm 250 B. but we have no idea what its spost to look like or what the real name of it is. he got the engine without a shaft and a wiring harness. Then he was offered the frame, suspension, tires, wheels exc. for 20 bucks. but the guy he got it from pulled the engine about 2 weeks before my friend got it. The previous owner had a certain like for his die grinder and cut the engine mounts right off the frame so were trying to piece this thing together but we have no idea what it looked like in one piece. someone help.

 

What you have is a 250 Moto-4, but I don't have one around to snap pics of to show you the mounts.

Try going to bikebandit.com for a parts breakdown of how the mounts look.

These things are abundant in most salvage yards. I would go there and get new mounts.

 

Holy crap that site has everything i need thanks a lot.
