09 KLR Won't Start After Running Fine

A couple weekends ago I took my bike for about a 50 mile ride, and it ran fine. Took a couple breaks during the day and it started each time with no problem. On my way home I stopped for gas, was low, but not on reserve yet. Filled the tank, drove home about 3 miles. Again all seemed fine. Then the next morning it wouldn't start easily. I finally got it running, and warmed up, but running a bit rough, so I shut it off. Then I went to restart it, and it would not start. I have not been able to get it started since. Pulled the carb to make sure it didn't have gunk in it. Looked fine, so I put it back in. Cleaned the plug. Filled the float bowl with known good gas, just in case, but still won't start. Any ideas? I've only owned the bike since this summer, so I don't know the history. It did tend to backfire at times when decelerating, so I've been running some SeaFoam in it, which I think was helping. I read through a bunch of threads here on the forum, but none seemed to have found or posted the fix for a similar issue.

Thanks,
Dean

Morning Dean I am far from the best help available on this forum, but here goes.... If it ran fine 'til the gas stop I would look real hard at fuel contamination. Did you actually have the jets out or just clean the float bowl? A complete carb cleaning is probably a good step. Drain some of the new gas into a clear jar and look for water or particles. I suppose that the SeaFoam may have loosened some trash that may be clogging jets. Eliminate the simple things first and don't panic ( that's what I usually do-panic that is) You will be able to sort it out Ride safe Rebar James in Friendswood Texas

Thanks. I'll try not to panic. Wasn't planning to spend the nice remaining days in New England with my bike not running...

Backfiring on deceleration is normal; it's a lean pop caused by the overall lean condition the carb is set up in from the factory. Seafoam won't help with a lean pop. A loose/leaky exhaust header gasket makes it worse; check that.

The 22 cent mod and richening the idle mixture can help.

Watch the videos to understand what that's all about.

To rebar's point, fuel contamination or crap loosened by the Seafoam would be a likely place to start.

All it takes is a bit of crap the size of a pinhead (no, not me, I'm big) to clog up the carb.

Cleaning requires complete dis-assembly, but it is not that hard.

Watch the videos to understand what that's all about.

Apologies for the wheedling narration and the less than perfect video production standards. The guy is a pinhead...

Attached is a pretty good description of the carb. Read it, know it, live it.

You're welcome, Medicineball.

It's an oldie but a goodie. I saved it as a .pdf because the websites that have hosted the html version have come and gone and I was afraid of losing it.

Redondo Ron, wherever you are and whoever you are, we owe ya a cold one for that document...

Nope, when the kill switch is off, the starter won't crank.

Unfortunately my bike is not running, and 45 minutes away. I'm away this weekend, so it will be another week at least before I can dig in some more... Summer's going too quick...
