What speed does your engine idle at when it is warmed up? If your idle speed is too fast, this could cause your problem. Does changing your idle speed adjustment make any difference? Also if you have a lean mixture, this could cause it to idle erratically. Be sure you don t have a vacuum leak, either at the carb, intake boot, fuel petcock or vacuum lines. A partially plugged pilot jet could cause this too. Does your bike start normally? Make sure your throttle cable has plenty of slack (freeplay), you should be able to turn your handlebars to the far left and right without changing idle speed. You should have 1/8 to 1/4 freeplay on the cable at the grip.

If I shift and hold the clutch instead of changing gears, it takes about 5 seconds to rev down to idle. Thanks, Larry 03 KLR 650 [Non-text portions of this message have been removed]

<><><><><><> <><><><><><> Michael, I think you have at least two different issues going on. First is the poor running and now no start condition. Second is the neutral light situation. My guess from your description of an evasive slow is that you were braking very hard. When you hit the binders gunk in the tank/float bowl moved/got stirred up. As you continued to ride it clogged carb jet(s). So for the no start condition I think the first thing I'd try if I was working the issue is cleaning the carb jets by removal and visually inspect them. Shouldn't take more than about and hour. I'm gonna guess the pilot jet is clogged and the main/needle jet is mostly clogged. If that doesn't fix the issue I'd probably check fuel flow from the petcock and also check for spark with a spare sparkplug so I didn't have to pull the plug in the bike. For the neutral light I'm gonna guess you have disabled the clutch switch. If that is correct I'd start with checking in that area. If the wrong wires touch electrically it can put the neutral light on in gear. I suppose it could be an issue with the neutral light switch but I wouldn't look there first if I was working on the issue. I was just thinking it would be helpful to know the year of the bike and then saw you posted that in the subject. 2008 model KLRs had a recall for harness issues. The poor running and no start condition are what many report when they have a rub through in the main harness near the steering head. If I recall correctly there are 6 areas that bear attention on an 08 KLR. I don't have one so I've never had to mess with an inspection. I think another area is under the seat and also under the tank. It takes a bit of time and effort to inspect the harness but I'll bet you could have a rub through issue. So now I'll suggest you have three issues going on. : ) Best, Jeff Saline ABC # 4412 South Dakota Airmarshal Airheads Beemer Club www.airheads.org The Beautiful Black Hills of South Dakota 75 R90/6, 03 KLR650 . . ____________________________________________________________ Mom Lazy Way to Look Young Doctor Reveals Way to Look Significantly Younger in 17 Seconds http://thirdpartyoffers.juno.com/TGL3141/507a711012871710f2acest01vuc
