I've got close to 12,000 miles on my bike. I've been reading up about the routine maintenance in that mileage range, and I know it will include a valve adjustment, and I already think my input shaft is going out, but is there anything you guys would recommend having done?

 

I always check brake pads, chain/sprocket, battery connections/fluid, antifreeze, a once over on all bolts/nut during every service. your life depends on the operation of that motorcycle when you are on it, so you cant never short yourself checking everything once and some things twice.

I made up a check list/sheet of everything I should inspect on a routine basis, had it laminated and during each service, I use a magic marker and check each off as I check part, at the end of your service, you just have to use a paper towel to wipe clean and you have a new list for the next time.
