I picked up a '06 Nomad 1600 last night. I noted two issues. First one is the drive shaft boot is cracked. I did some reading here, and I think I can just patch it up for now to keep dirt and water out. Second issue is the Mode button on the digital display is not functioning. I've read that it might be a lost cause since it's not really serviceable, but someone did mention replacing the circuit board rather than the entire meter assembly. Anyone have any input on that? Finally, one of the little rubber button caps on the meter cover is missing. Is there any source for dinky little parts like that as opposed to buying a new cover for $140? I may resort to sticking a small cork in the hole to keep water out.
