Front wheel bounce

[93Bandit]

Hi everyone,

I installed a new front tire and balanced the wheel, yet I'm getting a front end bounce around 40mph. I've read tension in the forks can cause this, and I read a procedure somewhere to remedy this issue but I cannot find where I read it. Something to do with loosening the fork and axle bolts, then retightening in a certain order. Can anyone clarify the order for me? Any additional tips?

Thanks!

Bike on centre stand.
Leave the top fork clamp alone.
Loosen the bolts on the lower fork clamp.
Loosen the bolts holding the fender / brace
Loosen the axle and its clamps.
Bounce the front of the bike down onto the tyre a few times.
Tighten everything back up, working upwards.

...and if that ^ doesn't fix it, it's possible your tire bead is not seated. Look closely and you will see a fine line on the tire near the rim. Any dips indicate a bad seating. It can be noticed spinning the tire with a rod or pencil or chalk piece clamped close to the tire as you spin it.

I think this did the job! I loosened everything, bounced the front end and tightened back up, going from bottom to top. Then I took the wheel weights off. Rode down a smooth road and she's nice a smooth.

Yes, I double checked this first because that was a concern. I even broke the bead, put in some tire lube and reseated the bead to ensure it was centered. Seems to be fixed now.
