Any quick idea what may be the trouble with the idle. It'll idle slower and slower until it dies then I've got to restart it while pulling on the throttle and it wont idle until it gets good and warmed up with me putting on throttle.

usually i'll idle it with the choke on, the RPMs will slow over the peroid of 30 seconds until it stalls after which time It wont start with the choke on at all. I'll close the choke and restart it. At that time it will idle very slowly and stall unless I have a wee bit of throttle on and keep it on until its thoroughly warmed up. Sometimes none of this happens. Its usually just fine with 30seconds with choke on, turn choke off and its good. But like i said, sometimes it'll act up for whatever reason. Seems to be more pronounced after I fill up but that could just be my imagination.

Your idle is too low..... adjust it till it runs ok.

It should be noted that the idle spec is a range not a set number (1000 to 1200 rpm) . This is due to the nature of the single cylinder air cooled carbureted bike. Idle speed changes a bit with operating temp and weather conditions. That's why there is a easy idle speed adjustment......

On a side note, it may sound neat to have a low idle, but at 1000 RPM the oil pressure is only 2 PSIG. The other day I took idle down to 900 and the needle on the gauge almost touched 0 psig......

Okay, I upped the idle a little more than a week ago and it did fine...until now. I topped the oil off a few days ago and checked it today before i took off so I know Im not low on oil. I AM due for an oil change. I've been topping it off but Im at about 3k mi on it. Tomorrow I'll check the vac line for gas and change the oil. As long as Im changing the oil I'll check the oil filter and make sure it isnt fouled with plastic from the cam chain guides (please god no). I REALLY dont want to have to take the gas tank off and check the plug but i suppose it could be fouled. SO....barring gas in the line, old oil, clogged oil filter, or fouled plug what could I be looking at?

Look at the weather. I am constantly amazed at how the weather affects the way my bike runs. Especially temperature. We've had a few cool days around here (39 degrees the other morning) and the bike is running like a striped-assed ape. I'm thinking it's a little too rich on warmer days, 'cause it sure doesn't jump away from stop signs like it will right now.

Any black smoke at idle? Could be rich... Also the carb slide and diaphragm, could be sticky. But check the other stuff first.

No gas in the vac line. Oil changed. Oil filter good. Didnt check the plug. No smoke. Seems to happen usually right after I fill up. I fill with the bike on the sidestand up to the bottom of the filler neck. When the stalling happens The first thing I do is take off the gas cap and switch to prime. No whoosh of air in or out but the bottom of the cap is usually covered with gas so I suppose I could be submersing at least one of those little vent holes and creating a vapor lock.

I don't think it's the vent holes in the gas cap. they shouldsuck air in no problem, that is if they are clear & clean. BurnPgh, Where are you located?? I vaguely remember you telling us in another post but the mind isn't as sharp as it use to be. T Mack east side of PA.
