KLX running very lean
Just took the bike out of summer storage; I had drained the fuel tank. With fresh gas, it starts right up and runs OK (but too fast) on choke, but leans out and is lacking power when choke is off. Plug is very white after short ride. Drained float bowl, no change. Air filter is new last spring and still clean. Do I have an intake air leak somewhere? Any suggestions for troubleshooting??? Thanks from Naples, FL.

If it was running fine when you put the bike up, I doubt you have an air leak. Unless you did some extensive work of some other kind during storage, your problem is probably in the carb. It sounds a bit like a partially plugged pilot circuit and/or other residue in the carb from storage. I've come to the conclusion that just draining the carb before storage doesn't always insure a successful start-up later on. It seems that some residue still gums up the smaller circuits in the carb. I've started insuring that my fuel in the tank and carb is fully treated with a fuel stabilizer before shutting it down for long periods. It seems like the stabilizer keeps the pilot jet and other small circuits clean even as the fuel in the carb evaporates to some degree. I used to think that fuel stabilizer was more snake oil than not, but I've changed my mind after not having start-up issues on everything from my chainsaw, lawn tractors, and motorcycle even after long periods of inactivity. I'm thinking you'll need to pull the carb and do an extensive clean-out and blow-out with some spray can carb cleaner and compressed air.

go down to my post #20, under CVK carb, and see a link to an HMF forum thread that is pretty good CARB REMOVAL INSTRUCTIONS.

Kawi ditched the TPS in the 09+ models. Didn't do anything anway from what a few members here found with some testing.
