i have a 03 rincon with 800 miles on it. i've had it for about 9 months now. i don't trust any local dealers to service it for the obvious reasons. it runs great in every way, just did oil changes myself. did'nt get the shop manual yet, the valves have not been checked yet at all and i'm getting nervous. is the valve clearance adjustment really bad or could i do it with minor informational help? btw been doing engine and trans rebuilding for 30 years now.
