Hi all, My KLR is suffering from what feels like a case of sticky throttle cables, except that it's not, because they move smoothly and easily. Symptoms are similar, though: when I release the throttle the revs go down more slowly than they should, and sometimes when I blip the throttle it seems as if the revs even keep increasing for a moment after I've let go. I haven't dug into it yet to try to figure out what's up, but if anyone has helpful suggestions, they will be appreciated. Thanks, -Lujo [Non-text portions of this message have been removed]

Maybe your main needle is slightly bent, and causing it to stick. Dave

If you've ruled out the cables themselves it is *almost* certainly carb related. Could be a couple of things... dirty carb causing the slide or other parts to stick; a hole in the carb diaphragm or in the choke enrichener circuit diaphragm. I think you gotta pull the carb either way - unless someone else can think of another cause? dat brooklyn bum (I'd suspect the choke enrichener circuit first from the symptoms you describe - it happened to me that way)

Seems this was just tossed around a while back. If my failing memory serves me, it was the carb diaphram that caused the slow return of the slide on most of them. Seems HD has a replacement part that needs slide drilling or something, or can get a coating compound at NAPA auto parts stores to spread over the suspected hole/tear to seal it.

Pretty bad replying to myself here... But after hitting it noticed I forgot something. The choke (enricher) would my first check, since it could just just sticking, play with that first and see what you find. Dooden

Lujo, *) Sticking slide inside the carburetor? *) Sticking twist grip? I have had this latter problem after installing new gel grips that had a binding problem with my bash guards. It led to a very embarrassing low speed crash. I had to trim off the outermost 1/8" of my new gel grip to get the throttle to snap quickly back to idle when I let go of it. Maybe spray some aerosol lubricant inside the throttle twist grip to be sure there is not any dirt impeding the free and rapid release of the twist grip? -- Marc, KLR650 A12 Date: Wed, 5 Feb 2003 17:25:47 -0500 From: "Lujo Bauer" Subject: sticky throttle Hi all, My KLR is suffering from what feels like a case of sticky throttle cables, except that it's not, because they move smoothly and easily.

Damn fine suggestion Marc. I had forgotten about that. By about the fifth day of the Alcan I had a throttle lock made out of dirt! It was fun to pass people waving both hands (don't try this at home....only far, far away from home!). dat brooklyn bum --- In DSN_klr650@yahoogroups.com, "Marc Illsley Clarke, W2MIC" wrote:

Thanks for all the fine suggestions, everyone. This list is really awesome. I checked for mechanical problems related to the throttle cables, twist grip, so unfortunately it isn't that. I'll pull off the carb this afternoon or tomorrow. I'm planning on just pulling it out without going through the whole factory-manual-recommended procedure; hopefully that'll work. I'll report back if I find any interesting problems. Cheers, -Lujo [Non-text portions of this message have been removed]

Do you have any handguards that attach to your bar ends? Are you using and bar end weights? Do you have any tight radii bends in the throttle cables? If your using handguards that attach to the ends of your handlebars, you are most likely rubbing. A small bit of trimming or liquid silicone fluid will loosen that right up. Same with bar end weights. If you have your throttle cables too tightly bent as they head towards the carb, you can also suffer sticky throttle problems. Check these out before you tear into that carb cause it can be a pain in the butt. jim_ama585601 [Non-text portions of this message have been removed]
