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.

Long shot: I've noticed KLR tachometers go crazy when the primary electrical power connections (e.g., battery terminals, ground terminal) are deficient.

Won't hurt anything for your to examine and re-tighten these connections (they may LOOK o.k., but looks can be deceiving). Your load may have caused some anomaly in the cable harness connections.

The wild tachometer is my clue to this possibility.

Again, I SAID it was a long shot!

Hey, you try carrying a 2x2x2 box of aluminum cans, newspapers, etc. and someone tighten your straps and see if you don't limp along. Sorry Clogan, just couldn't resist. Good thing you don't know where I live, eh?
Seriously, I don't have the slightest idea what that is, but I'll bet someone here does.

Agreed. The anomaly you felt in the engine and seen in the tach indicate to me a poor ground. Check the battery terminals fist and work back. Simple things first.

Gray-haired riders don’t get that way from pure luck.

I had some bungee cords hooked to signal light brackets, others hooked to other non-routine places. Since I was toting such a large, relatively heavy load, I had more bungees in more places than ever. Then when all bungees were removed, bike performance returned to normal.

All this tends to point to a bad ground created by, or worsened by, some or all of my many bungees. I'll take more care next time in where and how I hok my straps.

Thanks, guys!
