Hello people,I has bought a motorcycle Honda cbr600 f2 (1991)and I changed the engine. I removed old engine(cbr600f2 1991) and I pu (cbr600 f3 1995) but now it's not working my clutch I can't get 1 gear or neutral or other gear.Does anyone nows why?thanks

 

So many questions.

Are you sure the F3 clutch worked before you installed the engine?
Did you at any point take the F3 clutch apart?
Are you sure it's the clutch?
Or is it the transmission? (Not being able to change gears and clutch not working are 2 different problems).
Are you rotating the rear wheel while trying to change gears? (You can change gears without using the clutch).
Did you reverse the shift linkage? (F2 and F3 have reversed shift drums).

Not sure why I answer some times...

 

If nothing else, if someone else at a later date is attempting this they'll have it for reference.
