    well, you can take the ethanol out, but that's what they're using for Octane these days. I use racing gas in my bikes that have carbs and sit. It's a night and day difference

    Great points. I have non-ethanol available to me, which I have used most of the time. But more than that, I have drained the tank and used fresh gas at least a couple of times over the years.

    I am pretty certain the cam timing is good, primarily because it runs well and is not lacking for throttle response when started and warmed up. But I will have to double check it now.

    Thanks for the ideas.

    Refresh my memory...

    Does the KLR250 have a vacuum operated fuel tap?

    No. But it has the filter straws in the tank and a tank vent that clog. I wonder if fuel is slow filling the bowl?

    Flow is good, was just out trying to start it again. 25-30 kicks with barely a sputter. F me. It will sit for a while again while I'm away for a week.

    Compression check. Feel for spark. Try starting fluid. One will let us know whats up.

    Maybe it's an ignition problem

    It'll be about a week before I can get back, and get back to it. I'll check basics and let you all know. Thanks.

    @enumclaw sounds like just about everything has been mentioned already, but have you tried tweaking the pilot screw? it can be quite lean from the factory...
    my bike does not cold start first or second kick unless I ride it daily, but once i'd fixed the air leaks and bad valve clearances that it came with, backing out the pilot screw a little bit more really helped

    some versions have the pilot screw covered by a plug or cap that can be drilled out if you're careful, i'm sure that's documented elsewhere in this thread

    @enumclaw how does it feel when you kick start it? is it easy? could be the KACR as Greasy mentioned... my bike would stall some times because of this and it would always take many kicks to get it going before I completely removed the KACR from the exhaust cam...
