Something I have been wanting to ask about is who uses what sort of fuel additives. Never found anything about it in my manual but then again you don't see it in car manuals either. I hope to get some responses to this so asking, what does anybody use? We use EFI/intake cleaners in our cages so why not our bikes? Mine is an 01 and has a carburetor but even in older vehicles aw well as new I like to use Lucas fuel system cleaner.
