Happy holidays folks. I'm new to this forum, just bought a 97 CBR900RR. This thing is like brand new. Totaly stock. The only problem is it has a spun bearing. I am looking to maybe swap a different engine in it. I've heard that a 916 will fit and that a 954 will not. Was wondering about the 929. Any input will be appreciated. This bike is too clean to let die.
