I was riding home last night and my bike started actin funny, it would die when I stopped it would start with full choke and run while I fiddled with the choke between open and closed. I made it home, luckily I was only 2 mi.out. today I cleaned up the motor and started process of elimination fuel line, filter, sparkplug dry n tan. I pulled the carb slide out and the mainjet had rattled out so I pulled the carb cleaned the jet put loktite on,figured while it's open I'll check float height it was at 5/8" or16mm i set it 21mm,i took it for a ride it runs good @WOT,but it has flat spot in the middle, needle is set on topnotch. Anyone have a suggestion?
