Won't Start

I just purchased my first KLR 650 (7-31-13), The guy I got it from said it was in great condition, with less then 8000 miles on, I test drove it, everything seem fine. Drove it home, no problems, The next day I drove it to work in the morning, rode nice, At lunch when I rode it, it started to cut out at stop lights, like it wanted to die. I had to bring up the RPMs to keep it running, When I got to work I took my hand off the throttle to see what it would do and it died, but started right up and idled. So I thought no big deal, after work I went out to ride it home and it wouldn't start, I was like great now how am I going to get home? I messed with the choke lever and pitcock and somehow it started, I rode home down the Highway and in stop and go traffic it again seems to want to die. When I did get home I took my hand off the throttle again and it idled just fine. Today when I went out to ride it, it would even start just, cranked. Any help would be appreciated .

Clogged fuel filter? Contaminated or very old gas?

Could indeed be a fuel quality problem, IMHO. Draining the fuel bowl and insuring fresh "dry" gas might be a good first step, IMHO.

Lots of other possibilliies (e.g., vacuum-actuated petcock failure, fuel tank cap vent compromise, etc.), but . . . beyond the scope of definitive long-distance diagnosis without more detail; again, IMHO.

Agree with Damocles, open drain on float bowl to see if there's any fuel in carb, if not induce vacuum on hose at petcock(not the one that goes to carb the other one) if there's fuel present at the vacuum hose could be problem with petcock(don't swallow the gas if present,Ha Ha). If doing this you get fuel to carb then this area is fine, might have to look into carb. Try engaging choke(enrichner) no throttle and see if it starts. Let us know what happens others will be happy to help if you let us know. Good Luck.

I'm lazy, so I'd dump a can of seafoam in with the gas, let it sit overnight and try again.

And yeah, my first thought was the gas cap not venting, but that doesn't sound like it, but it's the easiest thing to rule out. Open that puppy up and try to start the bike, ride with it open for a while. That drove me crazy with my old bike. Same deal. Got it used, died after a few minutes. Gas cap vent was jacked.

PS - Seafoam is fairly cheap and won't hurt a damn thing. It can only do good.

I know, I know, I always think it's a vacuum in the tank problem, open up the gas cap and take it for a ride. If it helps we can talk more.

Might be a stupid question, but then again it might not be: Are you out of gas? Screwing with the petcock might have put it to reserve, which was enough to start.

I only ask cause I've been down this road before. Better to not spend hours obsessing over every possible explanation when the simplest one might have fixed it.

No, not out of gas, I went out a day later, stuck the key in it and with loud bang that sounded like a gun going off she fired up, ran and idled perfectly. I'm thinking it back fired because of the gas that may have been built up in the cylinder from when it wouldn't start. Another question. I shifted the shifter down and up before I try to start it and then it started, Does this have anything to do with the Doohicky mod? and would the Doohickey keep it from starting? Is it a neutral safety issue that could be preventing it from starting? Oops, I found out the Doohickey Mod is for putting tension on an internal chain, My bike has less 8K on it, So I'm not sure I need to do this Mod yet.

I am having this same problem and have an active thread going on it right now.
Next time it dies, hold the throttle wide open when you crank it and I bet it starts right up.
I can also keep it from dying out if I raise the idle to around 1700 or higher.
Let me know if these help, and hopefully between these 2 threads this can get figured out.

Yeah it did it again, I tried the Carb and injector cleaner route and that didn't work. I took it for a long ride today and it did fine. Got home and let it idle in the driveway and watch the tach needle bounce down and up until it died and then it wouldn't start. Held the throttle wide open and try to start it, nothing. did it with the choke close and open, Nothing happen. Really getting on my nerves. I'm thinking carb rebuild or replacing the Air/fuel needle and doing the slide drill out thing, with the #4 washer.
