I personally wouldn't bother with it unless something seems out of whack or performance has degraded.
I know that is what I side. the wheeler is at a dealer right now getting some things done on it and I was thinking about doing a service tune up and they said that if it sounds funny or runs funny it might be the carb from the gas sitting there. he was trying to tell me about the gas break down stuff. but I dont know maybe I wont touch it. and just have them do the service tune-up
