Just returned to Thailand and could not start the KLX. Took it apart and this is the state of my carb after letting the bike sit for 3 months with gasohol in the float bowl:
Main jet is completely clogged with this nasty gasohol residue:
This residue is not only on the parts that were submerged in the gasohol. It's also inside the jets and on the needles. Obviously a complete rebuild is necessary.
Completely my fault of course- I shouldn't have used gasohol in the first place and I should have drained the carb before leaving the bike, but it is what it is, and perhaps this post might save others from having to deal with a similar mess.
Happy Trails!
