Posted June 4, 20214 yr Hello im new to the Yamaha, and actually never had a motorbike before, so of course i decided to buy a Yamaha XS500 from 77' without any knowledge. Anyways seems like the carbs arent adjusted or atleast the right one. The left exhaust is clear, and only has normal soot, no oil or gas residue. But the right exhaust tip is filled with residue and stuff, and when the bike runs the righr exhaust smokes a lot! What can i do to fix this, i have located the air screw and seems like my fuel screw is already fully tight which makes no sense since the bike runs? What can i do?
