I recently bought a 2004 Arctic Cat 1m 900 EFI with a 159" track. While performing numerous repairs that the previous owner neglected to tell me about I discovered that the the steering post had rubbed through the boot on the the right side throttle body bell. I can not see any obvious damage that could be causing this. One dealer suggested replacing the engine mounts as they may have started to sag. Anyone else experienced this problem that has any suggestions ?
