Ok, here is one for the guy's that have been doing this for awhile.


I recently purchased and installed a GPR v4 on my 05.

I also replaced my front & rear tire with a Metzler M3.

My bike just does not feel stable above 140 mph.

Could the spacers on the front axle been installed wrong?

Could it be the spacers on the rear wheel or both?

Is there a specific way for the spacers to go back on, if so, HOW?

I have also replaced both fork seals which means they were taken off

the bike (the forks) and re-installed.

I had absolutely no head shake even without the GPR before I started

changing out tires. That is what makes me believe that it is something to do

with the wheels.

I torqued everything back to specs, but I'm unsure about the spacers

on the front and rear wheel.


Any help from someone who has dealt with this problem or knows about this

issue, would be greatly appreciated.

I haven't been able to take my bike over 140 with confidence and I am sick

of it.

I feel the need for speed.:thumbsup:

did you check the torque on all the pinch bolts on the fork assembly?Also check the fork height make sure they are even.

I have and 07 with the same unstability your talking about over 140 mph and I was able to eliminate most of it by lowering the front just a bit. Hopes this helps, that shaake is a bad feeling.

Yes to both. I looked up the torque specs in the manual that I d/l ed from here.

Thanks TREYZX10R

Is there any difference in the front & also rear spacers on the hub?

I'm gonna try dropping it 1" to see if that helps.

Thing is, that this didn't start until some tire changes. So that leads me in that

direction. The bike never had a stability problem before the tire changes

and didn't have the GPR v4 then also.

 

[hellsrazor]

I really need to know if anyone knows if there is a difference in those spacers.

Cause at this point, I am ready to disassemble the whole front end (forks

included) and put it all back together, step by step.

I'm also going to check my steering head bearing while I have it on the lift.

PROBLEM SOLVED !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!:thumbsup:

I took the front end completely apart down to the triple tree.

Re-assembled it, checking the torque on every stinking bolt & nut.

Took the front wheel up to the local Honda stealership, ( as that and yamaha

is all we have in my town). And had the mech re-balance the front wheel.

Took off all the wheel weights and started fresh.

Double and triple checked every fricken thing.

Took it out for a ride on the highway out of town and when the road cleared,

blasted that sucker for everything it had and held it.:thumbsup::thumbsup:

What a rush. Bike felt and preformed beautifully.

Front end didn't even nod in disagreement. Been awhile for that.

Back in tip top shape, oh yeah :thumbsup::thumbsup:


Also, a buddy called me today and wanted to race my ninja against his

02 busa. He didn't stand a chance. Pulled on him every single time.

I ain't talking no smack, he was like," You beat me man, I couldn't catch ya".

Life is good, winning is better.:+1:

2nd place is the first loser.:crackup::crackup::crackup:




Thanks for the input TREYZX10R and TESTIMONY3, rep sent your way.

 

[treyzx10r]

:thumbsup:awesome,glad ya got it fixed. I would've gotten back to you on the spacers but worked double shifts all week and did'nt even open the shop door.

I thought all the 04/05's had headshake? Mine sure as hell does and the GPR is only a small fix to the problem

 

[BattRECON]

Damn... this thread kind of made my night. Glad you were able to get that worked out without any major issues.

Aren't "Busas" the biggest most over rated pieces of crap you're ever seen? I love when dudes bring Busas to the track and guys on Ninja 250's crush them in the technical stuff. Don't mean to derail the subject but that makes me grin so hard it gives me a headache.

Mine does not headshake...I do believe that the 1st gens are more prone to it though.

Congrats on getting it sorted out.

Mine used to headshake like a muther fucker... well... now.. it doesn't at all.. You know what it is?? It's your right hand.. The throttle... Man these ZX10R... You gotta be really skilled to ride the damn thing smooth and not get head shakes.. It's beyond my skills sometimes... But everyone I track with seems to agree... By the way.. I race the ZX10R on the track.

When I first got my 1st Gen the headshake was BAD. I mean BAD. Now I still don't have a damper mounted, just new tires and it has not disappeared completely, but it has been reduced significantly.

 

[hellsrazor]

I personally don't know about all Gen 1s but, all I can tell you is that for a fact,

my 05 did not headshake on me at triple digits or WOT. It had low miles and

nearly new Pilot Powers. I changed F & R to Metler M3s and have had a little

nod here and there. Then had to put on Full Bore street / track 200 rear due

to financial situations.

Took off both front forks and replaced fork seals & oil.

After all this was done, Headshake started getting bad and unstable at high

speed and WOT.


So, I took it all back apart, checked everything out, re-assembled and

re-torqued every single bolt and nut. And let me tell you, it takes awhile to

look up each bolt and nut. Copy which bolt / nut gets how much torque, " lbs

or ft lbs. Done with it and it rides great now.:thumbsup::thumbsup:

So if you guy's with the 05's are having head-shake and have a few miles

on it and like the wheelies like me.

It might behoove you to try the same. All it cost was some sweat and a

skinned knuckle. lol
