It's been a busy Summer here and I've had a few periods when I haven't been on the KLR for a couple of weeks at a time.

I've noticed that after it sits for a couple of weeks, it's a little persnickety when it comes to starting.

When it's ridden on a daily basis, I roll it out, apply full choke and it starts right up. I leave it on choke for about 5 seconds then take it off choke and it settles down into a nice idle.

After it's sat unstarted for a couple of weeks, I'll use the same procedure and it won't fire on the first try. I'll shut off the ignition, take a couple of minutes to check and air up my tires and when I try to start it again in the same manner, it fires right up and runs fine.

I went through this last night and let it idle for a few minutes, then shut it off and pushed it back in the basement. When I leave to ride to work this morning, it's going to fire right up when I push the starter button.

No big deal, but it's kind of annoying. Anybody have any idea what might cause this issue?

I adjusted my valves at 5K miles and now have about 13K on the bike and am planning on doing them again this Winter. I'm thinking it's not the valves because it only does this when it's sat for awhile. If I just skip a couple of days of riding, the engine's just as cold as if it sat for 2 weeks, but if it's just a matter of 2-3 days, it starts right up when I press the button.

I run cheap 10% ethanol gas in it. Might just be time for a dose of Seafoam, I guess. I usually start running Seafoam in it at the very end of the riding season to ensure that when it's put up for the Winter, there's a healthy dose of SF in the tank, lines and carb.

If anybody's got any ideas on this, I would appreciate hearing them. I can live with it, but would really rather figure out what it is and see if there's something I can do about it.

I have the same issue. I figure the fuel evaporates out of the carb and it takes a bit of cranking to fill it again.

Yeah, I got no theories, but mine is the same way. And I would have suggested Seafoam. Because I always suggest seafoam. Even as a lite salad dressing in a pinch. :)

Is that on a Shrimp Salad?

Well, if it's a fairly common issue, I guess I'll just stick with the crank/check tires/start routine. Your theory seems sound to me, klr4evr.

Next time crack the throttle twice before you hit the e-start. Seems to help quite abit.

Works amazing on all bikes in the winter.

I don't know how much cracking the throttle will work beyond the psychological factor. Until you start building vacumn by cranking it over you won't have fuel flow.

My 2008 has the same issue. I never move my petcock unless I need to switch it to reserve. Could this be part of the problem? Should I turn it to off every time I put the bike in the garage?

I know its not a pumper carb klr4evr, but it works on every bike I have in the winter. Don't knock it until you try it.

phila my bikes don't leak any gas out of the petcocks so I don't always turn them to OFF, but its a good habit to do. I have bought bikes that were never touched and the seals dry up and either don't move very well or start leaking once I move them.
