Steering Wobble High Speed

Hey guys, Steve from So. Ill here (close to STL).

I have a 2009 K-9.

I bought the bike used in April of 2012, and since that time the highest speed I could go was between 90 & 100 MPH.

The bike would begin to wobble to the point where I would not accelerate anymore and begin to back it off until the wobbling subsided. I went to Gateway Big Dog in STL to talk with the guys at the shop.

They said the K9 should easily do 140-150 with little to no wobble. A couple of things they told me to check were: 1. Air Pressure, 2. See if the tire was cupped, 3. Fall away.

The air pressure was at spec and the tire has about 1000 miles on it (no damage). I proceeded to check the fall away and it seemed to be out of range a little bit, about 3" as opposed to the recommended 1-2". I adjusted the fall away according to the service manual directions and put her back together.

Took it out for another spin and this time I could get up to around 110 MPH before she started to give me the shakes. It seemed to improve a little bit, but still not the 150 i'm shooting for.

Any thoughts/suggestions?

First person to help gets a beer! :cheers:

Any help is appreciated.

Thanks

I agree. These bikes may have the power to get up there in the high speeds but 150 seems a bit much. You are risking yours and others lives doing speeds like that on these scoots. You'll find posts on here about the wobble at high speeds, seems to be a common thing.

Ive had my 06 up over 130 with zero wobble. If you set these bikes up right they will easily handle that speed, in a straight line of course.

I saw the clip on the news about this section of toll road, 40 miles long and $6.00 toll one way.:whoop:

Lot of accidents on tha stretch of road before they raised the speed limit. Even more now. Seems the feral hogs on the road at night don't really care what the speed limit is........

Glad I got the 'need for speed' out of my system years ago.

i guess a 3-400 lb. brick in the road would kinda fuck a person's day up. :bang:

I have been to 125 many times and have no wobble. I haven't been faster because I don't want to know it can out run my Daytona 675. I can set the cruise mate and run around 70 mph with no hands on a straight road (I do not do this often). I don't use beads and balance my own tires. I think it is important to have good tires on the bike and also be on a good section of road to check this out. Otherwise, you are wasting your time chasing what may not be a problem.
