I finished an extended assignment at work last week that had prevented me from riding for a while. I started up the bike, and it wasn't idling right after warming up (like not at all). It would only idle with the enricher on. I was able to adjust the idle screw enough to keep it running, but it sputtered. I thought maybe the gas had crudded up, so I put in some Techron fuel injector cleaner. This did not help. The bike was ridable with rough idle and backfiring on deceleration. It also took a while to slow down when I let off the thottle. I looked up the 'Keihin CVK40 Carburetor Primer' and learned about the coasting enricher diaphragm and air cutoff valve. Ahah! That had to be my problem, a torn coasting enricher diaphragm. I ordered a new one. In the mean time, why not ride it as it is? I went for a ride this afternoon to settle the turkey and cranberry sauce. All was well for about 20 miles, then suddenly I lost all power. The bike would idle fine, but seemed to choke and bog down whenever any throttle was applied. I had no power to go anywhere. Then I discovered that if I used the enricher lever as a thottle and didn't use the real throttle at all I could make the bike run enough to get home. I rode all the way home playing with the enricher and working through the first 3 gears (top speed was 30 MPH). Any guesses about what is wrong? -Bryan Tucson, A12

Got an inline fuel filter? If not, you probably have clogged up your carb from rust, dirt or stale fuel from the tank. You have to pull the carb and flush all the jets and clean the inside. --- In DSN_klr650@yahoogroups.com, "cactus_reese" wrote:

Your original problem sounds like a blocked pilot jet. Now it's acting like a bad carb diaphragm.

Or a blocked main jet.

I would say, rip out the carb and clean the sucker up real good. It sounds like a clogged SOMETHING in the carb. It sucks, but I bet your problem is simple once you get in there. MrMoose A8 (Barbie and Ken special)

Sounds a little like a diaphram with a hole in it to me. Big rubber part under the top of the carb. Auto parts stores I have heard sell a compund to seal these up, like a rubber cement stuff. Dooden A15 Green Ape --- In DSN_klr650@yahoogroups.com, "cactus_reese" wrote:

Did you drain some gas from the float bowl using the drain screw? Check for water in the tank? When the slide diaphragm went bad in my KLR in July at 70,000 miles, it did not act like this at all. The bike started and ran fine, just didn't have any power, and a top speed of 60 mph. Rode it with the bad diaphragm about 500 miles until I got a new one. IMO, it's not the diaphragm. You should be able to fix the problem by no more than removing the float bowl and draining the tank. Allan A14

Ahhhhh, that must be what's wrong with my friends Tengai that I am selling. I took it out the other day, and it was a dog. With alot of work, I could get it up to about 65 mph, but that was it. Other than that, it starts fine, idles fine, warms up good, and rolls down the road great, as long as your not twisting the throttle more than 1/4 of a turn. Anything past that and it just laughs at you. MrMoose A8 (Barbie and Ken special)

Bryan, Had the same symptoms as yours after my bike has sat for about 6 weeks, turn out to be out to be what looked like dried up varnish crud on the fuel side of the petcock diaphragm, cleaned it all up and it ran fine. Probably nothing wrong with your carb if the bike was running ok when you parked it, sounds like your just not getting enough gas to the float bowl. My problem was intermittent also.
