GSXR front end fitted - instability at high speeds
 

Helllooo....

had some k3 gsxr 600 forks fitted the other day to replace my K1 forks and went for a blast last night(on a private run way),
at highish speed around 95 the front felt a bit wobbly like my handle bars was going left to right fast but slightly. more of a wobble.

could it just be the forks are set-up bad or uneven maybe ?
I don't have any bar ends either can this effect the handling ?

at 70mph the bike feels fine. :smt073

any ideas .

wheel balance

who set them up for you?

Please tell me that you at least changed the oil before fitting?

ride to Preston and see Fud

when I had the front wheel off to fit front discs, the mechanic at york suzuki advised to refit the wheel but before fully tightening the axle nut, bounce the suspension up and down a few times to make sure the wheel is centered & true... Not entirely sure if this could have any benefit for ya but might be worth a shot

id say the forks are twisted, exactly the same thing when i came off my bike before christmas, apart from id get it above 50mph.. but they were very twisted

Re: felt abit unstable at high speed
 

I doubt the forks are twisted they have just been fitted by a reputable mechanic.

they haven't been set-up by anyone just left how I got them.

guy is well into his bikes i trust him and said they are fit to just bolt on, don't need a service or oil change.

I don't really know Fud do you think he would do them for me ?

Re: felt abit unstable at high speed
 

how much does this cost to have done,
and what's involved ?

Re: felt abit unstable at high speed
 

cheers for the tip but i don't own the tools to do anything like this, but as above they was fitted by a reputable mechanic . i know that doesnt rule out bad fitting but it feels fine going 70-75.

Re: felt abit unstable at high speed
 

just because they were fitted by a reputable mechanic doesn't mean the forks couldn't still be twisted ;)

thing to do to make sure they are not twisted it to undo all the bolts (4 of them) on the bottom yoke that hold the fork tubes in place do not undo the top yoke bolts then bounce the front up and down this straightens the forks "IF" they are twisted

its worth a try
