Sounds like you're not letting it warm up enuf. Try a cold start with full choke, no throttle. When the rpms start to rise (to about 2000-2500), use less choke, until it starts to rise again. Repeat until there's no further need for choke and the idle is steady at about 1000 rpm, then blip the throttle a couple times.
Might take 10 minutes or more, but when there's no stumble, it's ready to ride.

How about nailing the throttle and starting? -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
