Well,I had the stock Dunlop's on the bike,They were fairly new, I just wanted white walls.So I bought a set of Shinko777's, bike had the so called "death wobble" I figured just cheap tires, So I bought a set of Avon cobras white walls, Same thing. Get to 70 and the handle bars start a VIOLENT SHAKE! One time it didn't stop untill it got down below 60mph. Checked everything on the bike, can't seem to find one thing loose. I have not checked the neck bearings, but this didn't start until I started switching tires around, 2 sets of tires later, it still is doing it...ANY suggestions?

 

Triple tree may need to be snugged up. If you lift the front end off the ground and the front end flops over to one side or the other, you may need to tighten up a bit. Can't remember the exact amount but, I used to use a fish scale to measure. Should take like 3 or 4 pounds of pull to make the front end move. I'll try to find the exact weight is you need it. I set my at 5 pounds and it took the wobble out completely.

 

Fixing to go put it on the jack lift and see what happens..

 

never heard of that about the bars falling to one side or the other. mine has done that from the day i got it.

 

we would put it on a lift - pick the back up and look at the rear wheel tracking

if the belt does not have a gap on both sides of the pulley while rotating it than the rear wheel is influencing the front fork

and you were just in that location // did you un do something is the tab for the adjuster out of the stay ????????

 

Well, I put it on the jack, if I spin the rear wheel one way or the other the belt moves to one side.
The bars did not fall one way or the other as far as the front end goes..

 

Fall away test.

 

After you tightened the front axle nut did you loosen and retighten the cap nuts?

 

I don't understand that Kp.. I guess i'll take it to my buddy's shop and have him do it,or might just take a minute to soak in LOL

 

You tap the wheel to see where it falls on it's own to the side. Then to the other. I think you add it up so 2 either side is a 4 inch fall away. You only loosen bottom tree if you're going to adjust the tension on the neck bearing
