Sounds like (1) a blocked idle jet which makes it run lean at idle thus a varying idle, or (2) did someone adjust the throttle cables, and maybe got them too tight ??? Don't ask me why I know about #2...

Cheers,

John

Farkled probably WAY too much, but good 20' footer for sure. '96 KLR, '06 HD VROD, (girl friend hauler), '05 HD Electra-Glide, heh it's a HD and I'm old now ;-) and I'm proud of riding a 800+ pound bike at my age :-)

...sounds like there is crud in the carb. When you don't ride a bike for long periods, the deposits of oxidizing fuel end up in the bottom of the carb. My KLR is a '96 that I bought two months ago and I just did a jet upgrade on the carb. I was amazed at how much "crud", that is a scientific term ;-) was in the bowl! You are probably going to man-up and decide to pull the carb out of the bike and rebuild it. Sorry to break the bad news but "simple" fixes are likely to not work. You need to get a carb rebuild kit, because once it's out of the intake and engine side rubbers, you might as well do it right. I think it's your idle jet that is plugged but you can't clean that out w/o removing the carb. Maybe time for a jet upgrade at the same time and then you will be happy for the hassle of yankng the carb out. Keep in mind yanking a single carb out vs. an inline four carb bank is WAY EASIER (don't ask me why I know this!).

Good luck, ask for carb upgrades that cost upwards of $0.22 on this list ;-) and enjoy,

Wrenching on your KLR is half the fun,

John

Sorta on topic -- something we've all got to think about, so I'll open a different can of worms -- the semi-mandated ethanol blend gasolines are pure crap. I predict a lot of clogs and destroyed seals, o-rings, lines, etc -- particularly in older machines.

Haven't really found a solution. Using Sta-bil Marine. I think it helps. At least I feel like I'm doing something.

Don't know how Minnesota does it, but most of the "country" crossroads stations have pumps with real gas - labeled for "off road, marine, agriculture use". They're easy to find. That's where the folks with a little mechanical knowledge are lined up.

Sounds like your float is stuck "open" or there is crud on the fuel inlet valve or whatever it's called. The little needle with a rubber tip that lets fuel in or not based on float level. You're going to have to pull the bowl off and clean up what's in there.

Good Luck,

John
