Hey all, I just arrived in Colombia (currently halfway through my trip from Seattle to Ushuaia), and my '05 KLR 650 won't start. I just started troubleshooting it, so I'm still gathering info, but I figured in the meantime I'd list what I do know in the hopes that somebody smarter than me can point me in the right direction! So the trouble started back in Panama. I would be riding 60-80 kph, and occasionally feel a "stutter" in the engine where the engine would deliver zero power, and then pick back up. I stopped for gas at one point and when I tried to start the bike again, the starter would crank but the engine would not start. I began to pull the bike apart to check the spark plug, but before I got to it, I tried to start it one last time, and it fired right up. I was running late (I had to catch a sailboat to Colombia) so I figured I'd take a look at it later. The next 60 KM to the docks were difficult - the bike began to lose power suddenly, then rev back up, then lose power again. The only way to keep the bike running was to keep the throttle open and the RPMs high. I made it, though, and we packed up the bike and set sail for Colombia. Fast forward 2 weeks - I'm now in Colombia and the bike is unloaded and on dry ground again. I was able to start the bike at first (using the choke, I think) and it idled properly for about a minute, but when I gave it some throttle, it died. I haven't been able to start it since. Today I pulled out the spark plug and inspected it - it's covered in sooty black residue, which (I think) means it's running rich. I changed out the plug with a spare one that I'm carrying, and it still won't start. The air filter was a little dirty so I washed it out and now it's drying. SO... my question: where should I start looking? What's the next step? Thanks a million!
