Wonder what happened?
On my way to recycle center yesterday, carrying a 2x2x2 box of aluminum cans, newspapers, etc., and I had to pull over to tighten straps on my load. When I resumed, my engine started running rough, like I might be running out of fuel. When I looked down, the tachometer read zero. After a quarter mile or so of this, I geared back down to 3rd, and limped along at about 35 mph until I got to recycle center. After offloading my cargo, the bike ran fine on way back home. No stutter, no miss, no nothing. I never did have to go to reserve fuel, so low fuel was not the problem. I ran the 12 mile trip back home at 65 mph or so, just like normal. Tach resumed normal operation too.
Wonder what it was? Any guesses? I'd like to nip a problem in the bud, if I knew what to check for. Mine is a 2009 model KLR 650, with 9,300 miles.
