99 I/S stalling at stops and at speed

[Zman5558]

I have a 99 I/S, it keeps stalling. I can pull clutch, and will immediately restart. It happans while sitting at a light, and especially at any speed while driving. First thought it was kickstand switch, cause would stall when put in gear. but have replaced. Parts so far, have been new KS switch, new clutch switch, new plugs, fresh oil change, checked and repaired a few of vacume lines that were leaking, hard wired stop switch. When changed oil, seemed to improve, but today, (about 2 weeks since change), it is doing it again, sometimes 8-10 times within a mile. Bike is all stock, except exhaust,(glass packs) but those have been on for 2 years.

First thing, check your fuel system.  Does your fuel line have a kink in it?  Is you idle speed set at 900-1000 rpms?

Yes, to what Marty said about the fuel system.  Stick a ty-rap or similar between the lid and the tank and shut the lid of the fuel tank.  See if that helps.  If it does, your vent line might have a kink or some debris or bug in it.

Yes, idle at 900, actualy got extremely bad today, where I was having trouble keeping it going at all. Had plenty of fuel, and after reading about all the petcock issues, I switched it to reserve setting, and after about 5-8 seconds, it ran just fine and I could at least get it home. So I ordered the rebuild kit from eBay tonight, and hopefully that will resolve the issue.  Thanks for the help.

Bleed the clutch system.

Insure the clutch is not dragging.

I hesitate to respond to such base and juvenile responses, but only to point out, that to understand a comment one must read the total comment.  Evidently this fellow did not! So I will point out the obvious:

(to) "Insure the clutch is not dragging."

My  2cents, I'm with you sugarbear as I don't see that if the clutch was dragging that it could be the problem as described. Unless it only happened at a stop and it was intermittent. It sure sounds like a fuel related problem IMO. Alleviating the problem by changing the oil isn't clear to me.  Good luck, sounds like you got a tough one.

Wow bad day Mr. D? Not all might be as accomplished a mechanic as you and while you read disrespect into all replies it might not be as such. Cut the gentleman a little slack.

may want to check the vacuum line to the petcock... cracked or leaking.  If you have a Mity-Vac you could check the petcock with that and see how it is for holding vacuum.

Sugarbear, you will learn a great deal from this forum. There are alot of very knowledgeable people that post here including Mr. D. It just seems as though some folks come across a little harshly. It's not what you say but how you say it. Have faith and ask lots of questions. The valk is worth it.

When the engine dies, is it like the carbs are running out of fuel and the rpm gradually decreases, or, is it like the ignition switch was turned off and the rpm drops quickly?
