speaking of doohickey - torsion spring?

Is it time for Eagle Mike to design a fix? Capt. Bob Durham, CT USA 2006 KLR http://seniorbiker.blogspot.com/

Hey Blake! I did the balancer synchronization check/fix when I did my doohickey, but it didn't help much, if at all. My bike still vibrates at high rpm's. I just view it as a foot massage and ignore it . Looking at the mechanism, I just have to shake my head. This is no way to design a balancer mechanism. The problem is that it really isn't adjustable. The balancers on a lot of other bikes are adjustable so that you can move the weights slightly fore or aft to find the "sweet spot" that exactly counteracts the thrashing of the piston at your typical cruising rpm. With the KLR mechanism, you can only jump entire teeth, which is way too granular to do a real adjustment. As the chain wears and the guides wear, the whole mechanism slowly drifts, and there's no real way to "fix" it short of replacing major parts or doing some major machine shop work. For those of us with high-mileage bikes, putting up with some vibration seems to be pretty much a given, because the mechanism simply lacks the adjustability to compensate for normal wear and tear. _E [Non-text portions of this message have been removed]

Hi Eric! I'm sorry it didn't help your bike much. Unfortunately for me, the vibration is so bad that not only does it put my right foot to sleep after about 45 minutes, the vibration actually hurts my knee and I end up walking around with a limp. Putting my feet on the passenger pegs avoids the problem, but I'm sure that level of vibration isn't the best for the bike, either.

That is amazing to me some have the vibration problems. Mine has never bothered me at all even with metal dirt bike type pegs. It didn't even shake bad when a chunk about 3 / 8 inch long was missing from the doo. Irun Pro Gel grips and it doesn't bother me at all. Criswell

I wouldn't say that it is a "problem", but my KLR definitely vibrates. Even with the normal remedies, my (Honda XL650) mirrors can get a little blurry at certain rpm's. But it doesn't put my hands or feet to sleep, or otherwise discomfort me on long trips, so it's not a problem. I do note, however, that this is the main reason I don't put metal dirt bike type pegs on my bike. The stock pegs have nice vibration isolators built in. _E

Blake, You have a lot of interested by-standers on this one. I hope you will keep us well informed on your exploit. Capt. Bob Durham, CT USA 2006 KLR http://seniorbiker.blogspot.com/

Hello list: When I changed out the OEM foot pegs to the DR-650 serrated foot pegs three years ago, we (Jeff Saline and I) both experienced a noticeable reduction in foot peg buzz. Why? don't know, but it was better. Others may find/report the same. Blake, I am also with you on riding the passenger foot pegs when on the slab. It is a lot more comfortable to me than the stock peg position. YMMV, etal. revmaaatin.

Fred, please remove this guy from the list! He has crossed the line with this post! Jeff, if you're going to start being reasonable, you don't belong here. (LOL) Running for cover, Norm
