I have freshly rebuilt my carbs, they’ve been synced, I’ve adjusted the mixture screws to lean and to enrichen as a test. The bike sits and idles fine , has plenty of power , I don’t have to hold the choke excessively when starting and idling during warm up time , the bike accelerates fine and has no hesitation when revving either. I’ve also double checked for leaks on the manual petcock , vacuum lines , fuel line and everything in between but for some reason regardless of what I do , if you’re standing next to the bike while it’s running or behind it at the exhaust it smells like fuel, also to add, there’s no smoke whatsoever coming from the exhaust either and you can’t smell gas when the bike is off , just when it’s running. This is a 91 is that matters
