Please a little help with my Baggy HR wobble

[hadleye]

I have read a couple of posts on this and was wondering how many are using Steering dampeners. I have tried adjusting my forks up and down, adjusted my sag to about 75mm, and have changed tires and air pressures. I plan to use this as my track bike next year now that I have sold my beater Gixxer. I know the Supermoto Pilot race tires are not the best for stability but love the traction and extra shoulder area for extreme lean angles.

Some friends have seen the bike weave and wobble on the highway and are quite bothered by seeing it, most immediatly ask what is wrong with my bike. So now I am really wanting to put a dampener on it, scotts preferably. Does anyone make a kit, or do any of the protaper kits work on this bike?

Thanks for any info.

due to the type of bike, and the geometry of the steeling, they do tend to "wobble" a bit. mine never head shakes, but i would call it rut sensative. it does not bother me pesonally, but there has been quite a bit of talk of this problem with no definite answer. tires do make a diference, so does pressure. we did have one or 2 bikes on here with bad steering head bearnigs, so that would be what i check first, and make sure the wheel bearings have NO play, both front and rear.

look at the whole bike include rear swing arm bearings make sure rear wheel is runnig true after a chain adjustment
the tail can some times WAG THE DOG

and natural rider input is to fight or control the shake/wobble ...that usually
ends up turning a little wobble into a full blown tank slapper

we used to have a open metal deck bridge where i live and every thing
wobbled crossing it the harder you tried to make it go stright the more it wobbled on the metal grateing

i found that if i did not fight the handlebars but put more weight on the foot pegs it did better (bmw R50-S 1963)

I have noticed if I release my grip on the bars the wobble almost goes away. Bearings front and rear and steering head are tight, surprising as the bike is nearing 20k Kilometers. I have had dampeners on all of my track and race bikes, just for security and peace of mind which is why am planning it for this one.

play with lowering the rear a bit this will change the rake and trail up front

if your a light rider the bike may be seating too high at the rear
check the rear spring adjustment

my saxon tour has a very high angle to the forks and was a wild ride when i got it ...the 110/80-16 tire that is stock on it is not found in the usa
it had a 130/90-16 installed i changed that for a 120/80-16 and the spring loading was turned up for a big rider .. i turned that down for a light load ..doing both dropped the rear almost 5/8 inch boy did that calm things down

I installed a Scotts Stabilizer, see "speed wobble" in forum. Works great, highly adjustable.

I have had some of this wobbling but sorted it thus:

Check and correct wheel alignment - best done by measuring off from the rims NOT the tyres.
David Thompson is right on this one, in 30-odd years of riding one of the best bits of advice, from an old-time racer, was to always look at the other end of the bike - if the front feels funny, start at the back and vice versa.
Check tyre pressures with the SAME accurate guage each time.
Try holding the handlebars lightly - don't fight the wobble, it just gets worse.
I have tried various tyres and none are much more wobble-inducing than others so far.
Try shifting your weight forward. Although not the most comfortable, fast cornering works best on the Baghira with your ass where the designer intended - up against the tank!
The bike WILL follow lines etc in the road - this is due to the enduro/SM compromise in steering rake and trail and suspension.
Mine has not spit me off yet and I am definitely no ace...

Have you checked your wheels are "True"? If you have a slight buckle at certain MPH the bike will feel the brunt of the unbalanced gyroscopic forces and make the big shake. Most common cause is as Dave stated, check wheel alignment!!!

I checked the wheels when I put the tires on, they are very strait. I know it does it less with a light grip on the bars but am nervous that when I go to the track I may be worrying about other stuff and not remember to lighten my grip. I think I will go ahead and just put a dampener on it for my own peace of mind. Is there a kit that will bolt right on or will I need to rig something up?
