Hey guys I am new to this forum... I know a little about bikes and everything.. I just got my first bike back in july! a 1999 Cbr 900rr And after riding it awhile i belive one of the Valves bent and i was wondering if you could swap the heads.. like swapping a Cbr 929 Head to our Cbr 900rr's... If anyone has heard of this before please tell me.. or if it just cant be done please tell me also.. Thank you Very much
