86 VT500 hesitation at high rpm
I have an 86 VT500 that hesitates at RPM over 5000. Its a jerky on-off feeling. Anything under that and it runs like a champ. I've checked the air filter and fuel filter and both are clean. I haven't checked the plugs yet, still need to get the tool to remove them. I know pretty much nothing about taking apart and cleaning carburetors, are additives like Berryman B-12 safe to use on the bike? Are they effective? Or any thoughts on other things that may be causing the hesitation?
