very wiggly at 100 on the clock

First, I was very surprised at the 100. The road was very straight-level-empty and I just could not resist giving it an extra twist. So probably going what 75? Now the set-up: I sit back on the seat a bit because of leg length and arms like a tree swinging primate. The bike is stock other than nerfs on the front, an empty tank bag, and a sheepskin (alaska leathers and a great idea). The question: Are there any changes to the suspension set-up which will help with the front end wiggle. Thanks for the advice, albatross [Non-text portions of this message have been removed]

Maybe give the rear a bit more preload, if your sitting back. Tires (air/wear/type) will play in also. Steering head bearings might need some attention also. Just a couple ideas, besides the best advise, do not go 100 mph on a KLR. Dooden A15 Green Ape --- In DSN_KLR650@yahoogroups.com, "Terry Hamrick" wrote:

I'm adjusting the loose head set on my bike this weekend, because it has wiggle (wobble) between 70 and 85. No way am I going over 85. The way I checked it was to put the bike up on the center stand. Grab the fork tubes at the lowest point, and see if there's any wiggle. There wasn't much in mine, but I'm sure that it will have some effect. Check it out. There's lots of info available if you need to adjust the head set. Regards, Chuck

A racer friend suggested I raise my forks by 10mm and set my front tire pressure at 28psi. After doing so my KLR feels a bit more stable at speed - or it might be a placebo effect. Either way I'm happy. Also, I think you might want to sit a bit forward to get more weight on the front end, during those times when you are chasing the speed of sound on your KLR.

I notice that Kenda 270's give the same kind of symptoms (high speed wander/wiggle) when they are worn to about 1/2 tread depth. Others have said that they don't experience this so who knows? Some other possibilities: Turning up the rear spring helps some machines, -tire pressure can be really important (if low) for some machines, -check for steering head bearing slack, -give the wheel bearings a good check for slack. This was a common one on 4 cylinder Wings -swing arm bearing slack -some feel that the front fender can be a culprit but my bike's fender is the stock one and the symptom comes and goes with worn Kendas -pavement rear ruts bother some machines but not others -some feel that loose clothing and/or a death grip on the bars contributes. Haven't experienced but see the possibility. - Some feel that top box or rear rack cargo can be an issue. Some time I'll pull the Givi off with a worn Kenda and see if it has any effect when the tire is worn. A couple of weeks ago, my KLR was really dancing on the pavement wear ruts at a bit over 145 kph (87 mph) while passing a Harley on an uphill. The uphill was why we were doing 145 rather than faster (VBG). These Harley types who have something to prove and a macho attitude really annoy me, so I just had to show him! Oops, you don't think...... (VBG) The speed is pretty close on my bike as the speedo has been adjusted to agree with my GPS but I tend to still go by GPS speed. I do notice that the speedo reads about 10% high when the Kenda is worn down to 1/2. The speedo correction has to be done for a given tire circumference so I chose a new Kenda 270. Eric the Elk really gallops with the airbox mods and 160 main jet. If he had a bit more power we could show up even more of those macho types.

Thanks for all the suggestions.... I'll experiment and let you know what works. albatross

nklr- just an observation

I have spent the past month, sitting on my Summer deck, healing 9 broken bones, from my May 27, windshear induced wreck in Idaho. My deck is located between Mile Markers 221 and 222 on the Blueridge Parkway in NC where I have a clear view of the PW. Being bored to tears and feeling sorry for myself for not being able to ride as I watch the 100's of Motorcycles go by each weekend, I decided to note the number of riders wearing gear. This past weekend Fri thru Sun Evening, I counted 400 plus bikes with approx 90 riding 2 up. Bikes/scooters of every make, model and year went by, ridden by young, old and in between. Counted 15 KLR 650's. My observations, verified by stubby pencil/eraser and pain killers: Of approximately 490 riders observed approx. 37 were wearing ATGATT. Approx. 85 were wearing a MC jacket of some kind. The rest were wearing only a helmet. During the day, mostly shorts and t-shirts sneakers, some sandals. Early morning and evening, jeans and long sleeve shirts. 2 of the KLR riders were in ATGATT. 9 had only MC jackets on, 6 only helmet. According to the local Park LEO's, there is at least one accident on the parkway each weekend. I heard some out of this world stories, the most recent last week, where a rider swerved to avoid two deer, not seeing the third until it landed literally in his lap/chest as it tried to jump over his bike. Not only was the bike totalled, the rider lost many square inches of skin. The deer also kicked the living heck out of him, trying to get away. Unbelievable? Yes! Did it happen? Yes! I personally know the guys father and he said that his son had been accident free on a bike for over 20 years and while he wears only a helmet, he is a cautious rider. Day before yesterday, as I slowed to turn LEFT from the PW onto US 21 South a rider on a Suzuki passed me on MY LEFT on a double line. I guess he thought my signal light had been left on accidently. Having watched him behind me for at least 2 miles, riding so close at times that I could not see his headlight behind the tailgate of my pickup, I purposely flashed my brake lights several times to catch his attention and signalled much earlier than I normally do. I can only imagine how my wife and I would have felt, had we made the turn as we normally do and killed the rider or how his family would have felt. Please folks, when you ride, PLEASE ride with All The Gear All The Time. Wayne Barcomb Be back on the PW later this week.
