Don't forget about Adventure Cycleworks! Him & his son are up 24/7 for adventure bikers...
typically doing maintenance & minor repairs though. Bet you could get him to do waterpump seal if you ask NICE! Sounds like your up a creek without a paddle, wouldn't hurt to ask him for help, very trustworthy father & son team. Hes very capable but BMW guy but loved wrenching on my 990.
Remember to call CJ designs (of wisconsin) & he can "express" ship you parts faster than a dealer up there can prolly get you parts!! a fee may apply
