The 1996 RR I bought the other day is in desperate need of a tune up. I have already scheduled a tune up but my local shop won't be able to take the bike in until next week. In the mean time I have been using the bike to drive to and from work. But the bike just sounds like crap. I'm pretty sure it's just the carbs waaaaay out of synch. The two things the bike sounds like to me is 1) The old VW bug 2) When a bike hits reserve and those 3 or 4 seconds it takes you to switch the petcock over to reserve. Ya know what I mean? Can this do any harm to the engine? I'm not hard on the bike, just freeway cursing. Should I park it until I get a tune up? Or is it no biggie other than low MPG?
