Title: fork wobble
Post by: MonkeyMcBean on June 28, 2015, 12:42:46 PM

My front fork used to always track smooth and straight. Suddenly, it has started to wobble under braking and deceleration. I have no idea what is happening. Does anybody have any ideas? Thank you!

greetings monkeymcbean...

generally wabbles are from tiors... front or rear... or bent wheels...

butts wabble under front braking is generally warped rotor or whack bobbins...

butts i donts thinks you gotts bobbins (http://www.motobrick.com/index.php/topic,1132.msg10261.html#msg10261) on that seven fitty... so i would be looking for warped rotors 1st...

The wobble isn't due to braking, because it happens under non-braking too. Maybe I should gethe my wheels re balanced.

awech1tt... i musta miss interpreted "wabble under braking" as meaning when you braked you gotts a wabble...

so... if its not wabbling under breaking its proally not warped rotors...

only on deceleration... if feeling it in the forks it could be final drive pillion bearing going whack...

could be excessive freeplay in the headstock.  Have you checked?
