Well everyone knows what happened with my quad, here is my question. My mechanic says he may know where a bmw F 650 is for a good price. He says the internal engine is the same is this true? I need a piston and cylinder. He says it ran fine but suffered a crash. Thanks for any info. John

 

chiknhawk i just seen in the "whats in your garage" thread that 2BIG2FAST had a stock piston and jug.

 

F650 has a different gear ratio.

You should be able to pick up a jug for a pretty good price wiith all the people going to the 730 kits.

 

I have a stock bore cylinder and piston from a 03 ds. I removed to install my big bore. Piston oil ring broke upon removal. will need replacement.
