Wanted to share what I have been doing for the "wobble"
after reading many post on this forum.
Purchased a spanner nut tool to make it easy to adjust
steering head nut torque on my 08 DL650 with 20,000 miles.
Got it down to 30 minutes from start to finish using this tool.
Have other friends riding SV650 and Vstrom, so we can use
the tool on their bikes too. Left the Continental Road Attack,
3000 miles since new, on the front wheel while adjusting steering
head nut torque.
First attempt, the steering head nut was "really" loose, torqued to
32.5 ft lbs and backed off 1/4 turn, wobble was about the same.
Second attempt, torqued to 32.5 ft lbs and backed off 1/8 turn.
Wobble was better, but still there from 40 to 50 mph with hands
off of handlebars. Third attempt, torqued to 32.5 lbs, wobble still
the same as second attempt. Bike handled fine through twistys
after all attempts.
Next, removed front wheel assembly to check radial/lateral rim
run out with dial indicator. Radial & lateral measured less than
.018". Did not believe this to be the problem.
Installed & balanced a new front Bridgestone Trailwing 80/20
DS tire. Tested this morning and wobble "gone". Tested hands
off deceleration from 65 MPH to 30 MPH and front wheel smooth
This experiment has me wondering how a "new" Continental Road
Attack would ride with a properly torqued steering head nut.
This was not real stable, but it worked out:
