Does anyone know where there is a good place to buy performance engine parts for the F4 motors? I'm thinking about higher compression piston, maybe a camshaft, and possibly lengthening the stroke. Just kicking around ideas because I came across a good deal on a motor and have a roller in the garage. I'm thinking maybe a drag bike or something.

 

drop the motor, sell it, buy cbr900rr motor... call it a day

 

Does the 900rr motor fit without a ton of modifications? Just curious.

 

From what i'm told, it does. But that was just some random dude at some bike meet. Probably easier just to buy a 900rr or something faster haha...

 

I apologize for being blunt, but you need to drop this idea of turning a 600 into a dragbike, let alone a f4.

You do realize that there is more than just one piston and one camshaft in a f4 motor right? If by some miracle, you do machine up some longer rods for the f4, please post pictures.

 

I know that there is more than one cam and piston, in fact I know quite a bit about f4 motors and others since I have spent countless hours working on bikes. I just forgot to put the letter "s" on the end of my words there, sorry my typo got your panties in such a bunch.
