Agreed. I start my with no choke & let it futz until it quits. Then I close the choke & start it again. I twist the throttle slightly so that the bike has a fast idle, then I take off. I will open the choke part way after about 3-5 minutes. When the bike "feels" like it running good, I open the choke up all the way.

Leave the choke partially on for a little while while you're riding. If you turn out the fuel screws a bit then that will be minimized to only cold days <60 degrees. Due to emissions rules these bikes are set very lean from the factory.

Only ever happens in the first minute or so. Once engine's been running it goes away. I can stop, do some shopping, come back and it will be fine. If you think your carbs are clean (I cleaned mine in an ultrasonic cleaner and used a compressor to clean the tubes) I now believe my problem could be due to the rubber connectors in the system - from the engine to the carbs and the carbs to the airbox. Have a look at the rubber itself, if its perished or degraded and if the connection between the rubbers (in the airbox too) are rotten. I'm planning on fitting cone filters just to see what happens, but it's more complicated than I thought. Just a thought.

Then, when I take off, after shifting into 2nd, when I roll on the throttle there is like a dead zone where I get no acceleration; if I roll on a little bit more, then the bike surges a bit. 3rd to 4th and 4th to 5th, I don't seem to have this problem. -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
