motorcycle carrier for jeep wrangler?

[ROKLINGE@aol.com]

Call to all KLR650 Shade Tree Mechanics, I have a 99 KLR650 w/no mechanical mods, stock pipe, stock carb, etc... 7,900 miles on the clock. When I ride the bike I experience an ever so slight hesitation/surging motion during acceleration and during normal cruising speed of 55. This motion is slight and when looking at the tach, I see no variation in the needle to indicate speeding up or slowing down of engine rpm. The exhaust note also seems flat. The sensation is more of a seat of the pants thing (no jokes here...) after 32 years of riding, it just doesn't feel right. My BMW, nor my Harley (no jokes here either...see BIKER Oct. 2002 page 40) do this, so it's not my vivid imagination. Clutch doesn't seem to slip... Only thing I notice is a rapid backfiring during engine braking. I had the bike in for the 6,000 mile tune up @ 5,500 miles. Any clues or similarities to a problem you have fixed would be greatly appreciated. Please respond to roklinge@.... Ron [Non-text portions of this message have been removed]

I am having the exact same problem. I have an '01 with 21,000mi, but at present I have a carb from a '96 KLR (long story) with nearly stock jetting. I just replaced the overrun enrichener diaphram AND the exhaust pipe gasket. No change. Last week I did a half-ass carb cleaning with a can of brake cleaner and an air compressor, no fix. The next thing I'm going to try is pulling the carb and giving it a dip clean. Devon ROKLINGE@... wrote:

OK, as one shade tree mech to another, as far as the hesitation/surging - get used to it. As far as the back firing during deaccelration, there is an inricher diaphram located on the left side of your carb. The top of the bracket holds the vent tube opening. If that diaphram is leaking for whatever reason, you will backfire during egine breaking, or deaccrleration.

Mine 03 does the same thing. I thought that was the lean surging mentioned in the FAQ section and on other boards that I was going solve when I get around to drilling and removing the cap over the idle/air mix screw so I can adjust it out a turn or 2. Damn, you mean I'm going to have to go to plan B and trade that damn vacuum operated petcock valve ( that I can't make myself trust) for a real one?

If you are getting surging/lean spots AND backfiring, something's not right. I have my mixture screw out 1 1/2 turns and I'm still getting the surging and backfiring. Time for a proper carb cleaning. Strip the carb down to the casting, soak in horrible nasty chemicals for an hour or two, then blow out every passage with high pressure air. If I remember I'll take pictures and do a step-by-step.

My A11 had a lean surge at about 4000 rpm. A DynoJet kit and backing out the pilot jet fixed that. From what I've read on the List, the KLX needle and a new main jet will do the same thing. I didn't have the backfire problem, but the coasting enrichener system is the place to start looking. __Arden

I agree, except I replaced the coasting enrichener diaphram to no effect. Also, this is not normal lean-surging. I bought my A15 brand new, and rode around with the stock lean surging for the first 750mi or so. That was totally tolerable. This is a flat spot- if I open the throttle as slowly as possible, I get to a spot at about 1/16 throttle where further opening actually results in less acceleration. It goes away as soon as you open the throttle further, but if you can hold the motor at the exact throttle opening, the bike will surge very badly, like taking up all the slack in the chain and then releasing it. The coasting enrichener is set up assuming that the bike is jetted properly otherwise- if you have some crap in the pilot circuit, on the overrun the coasting enrichener won't be able to completely stop the backfiring. In my case it sort of farts and pops, not really very loud. Tumu's old KLR had a holed coasting enrichener diaphram, that backfired like gunshots unless you turned out the idle mix screw 3 turns or so. Devon

Before going into the carb first check the exhaust header flange bolts for tightness. An air leak there is the most common cause of backfires on the KLR. Kurt Grife [Non-text portions of this message have been removed]

Yes, also at $5-$6 for the gasket, it's cheap to replace. Not to mention the only other thing you have to remove is the rear master cylinder cover and the headpipe comes out no problem. Devon A15 Krgrife@... wrote:

If you have nad a backfire event, I suggest checking the boots on the carb. Sounds like you may have an intake leak. As everyone knows, check the simple stuff first. It's a lot cheaper that way.
