  Thanks for the tips Foggy. Whats strange is it does'n't seem to do it when I first take off after a cold start.Once warmed up it starts it.

    Yeah, I'm trying to work out a throttle problem also. The rpm tends to hang up when I shift.

Jon,

Your idle (pilot) circuit is to rich. You need to adjust the air mixture screw counter clockwise to lean it out and then re-adjust the idle screw to set the correct idle speed. Make sure you warm the engine up fully before you start to tune the carb.

    You might be right there, Chris.When I start this thing up cold, I can literally open the choke right away, and it will stay running.I haven't got my manual yet.The idle adjust screw is the big knurled screw on the left side. Wheres the air mixture screw?

The idle air screw is the single brass slotted 'screw' to the right of the large idle adjuster nearly flush with the body of the carb. Two to two and a half turns out from fully closed (ie wound in clockwise) is about right.
You do need to get the bike warm first before altering all these settings and don't be worried if your bike likes to be 1.8 turns out or three turns etc. They are very individual so no hard and fast rule. Little turns/tweeks on the screw are the order of the day though to fine tune it. Great handfuls of 1/4 turns etc on that screw make huge differences!!!!

And be gentle on seating the pilot screw when re-adjusting - it's brass.
