There was a pretty good wooble on my front end. It looked like the triple tree was uneven on the forks...one side was a little higher than the other, and the bars seemed to be turned right a bit when I would go straight.
I had the dealership fix the uneven forks and replace the fork bearings, but there is still a small wobble (can't take both hands off at 30+ mph), and when I am riding straight, it feels like the handle bars are cocked right a little.
Dealer says a new front tire will fix the wobble, he hasn't addressed the cocked steering. New tires go on on Saturday, but what do you guys thinks this could be. Any ideas at all would be helpful.
Fork bearings!? :wtf: You mean wheel bearings, and you should have your suspension dialed in! Or it could just be uneven tire wear! :thumb:
Oops. I thought there was some sort of bearings in the fork. At least something. Sure maybe wheel bearings then. :thumb:
Could uneven tire wear make the bars look crooked while going straight? I'm going straight, but pointing a little to the right.
Front tire cupping would do it. Steering head bearings would do it. Shit put together crooked would DEFINITELY do it.
I'd start with making sure the front end is together right.
If you're at autobahn, look me up and I'll help you out.
Thanks for the tips, I'll have them look at it when they put the tires on.
It was crooked before they fixed the fork problem, and it's still crooked, so I'm assuming it was put together correctly (hopefully) when they did that. What is tire cupping?
Sounds like the forks are twisted in the triple trees. has this bike been crashed?
Tire cupping is caused by bad compresion and rebound settiongs. Usualy compresion (to soft), but the rebound needs to compensate for the compresion setting and spring rate as well! If the bike only has springs to rely on the tire will bounce and cause tire cupping! This could also be a sign of bad fork seal or seals, check for leakage! Strattle your bike as if you are riding it, stand up w your hands on the bars, w the front brake applied and push down on the front end if its goes up and/ or down fast or feels springy then you know where to start! Hows that sound Jeff?
The bike has not been crashed. I'm interested to see if a new front tire will fix the problem. We'll see on Saturday. I will let you all know. Thanks for the responses.
Now ya know damn well that bike's been crashed at SOME point in it's career!
To fix the fork misalignment, you need to support the front end by the steering head pivot, or else find a way to securely support the bike with the front end hanging free. Next, you'll need to loosen every bolt that holds the front end together.
1) steering stem nut (There on top of the upper triple clamp)
2)fork pinch bolts on upper triple tree (Clamps the upper tree to the fork legs)
3)fork pinch bolts on lower triple tree (Clamps the lower tree to the fork legs)
4)front axle
Needless to say, if you haven't supported the front end, at this point the bike would slide down the triple trees until it landed on the front fender!
Hopefully, the parts are twisted in assembly. With everything loose, now re-tighten the pinch bolts on the upper triple clamp to fully tight, and just barely snug the steering stem nut. Set the bike back on it's tire, and bounce it a few times. Tighten everything and ride it around the block.
If that doesn't fix the misalignment, something is bent. Possible culprets would be one or both fork legs, the upper and lower triple trees, and the front axle. SVs have a notoriously flimsy front end if the bike has ever taken a direct hit to the nose, I.E. slamming into a tire wall or bouncing during a crash and landing on the front wheel.
You might want to check the front rim for straightness, too! And find out for sure what the dealer changed. Was it wheel bearings, or steering head bearings?
Didn't you buy Tom Short's bike? I can tell you it has been crashed...
You can put a straight edge between the forks to see if they are bent as well.
Yes, I did buy Tom's bike...but that one has treated me really well so far, excpet for one thing, but I'll ask that in another thread.
The bike I'm referring to here is my street bike...it's a 2000 R6.
Thanks for the responses again!!
I got the qualifiers put on today. Rode home in the rain. Even with the rain, these tires feel stuck to the ground A LOT more then the Maxis I was on before. The bike just seems more solid or connected to the road. Can't wait to try some curves.
The wobble is completely gone!! So I guess there was something wrong with the old front tire. HOWEVER, the bars are still cocked right just a bit...not as much as before, and maybe now its just an illusion, but it seems like they are right just a hair. Any ideas what this could be.
BTW, they replaced the steering head bearings, checked the wheel bearings, checked out the rim, replaced the tire, check for the forks being straight...haven't come up with any reason it would seem this way.

Is it JUST the bars that are cocked?? Rim and all look straight cupt for the bars?? Ajust the bars so they are even. :biggrin:
That's the thing. The bars are straight...rim is straight...frame is straight. But to go straing the bars are a little right. Does that mean that my axle or whatever holds the tire to the forks may be crooked? I just don't get it.
maybe your eyes are crooked! :err:

I'm going to guess that the bike is an older R6 like pictured in your avitar. If the bikes been down then the lower triples are probably tweaked slightly. From 99 - 04 the lower triple on the R6 was really weak and would bend easily, even on a simple lowside type crash.

Funny...I only have one good eye anyway!! Can't see out of my left all that well.

Do you think it's dangerous to ride like this? Again, its only slightly off center.

I don't think it's dangerous but certainly not optimal and it would drive me crazy. Moving parts could be binding slighty and cause premature wear or ultimately damage the parts.
One way to get a quick check on whether or not you have a slight tweak in the front is to remove the front wheel, fender, upper and faring stay. Place a straight edge across the front of the forks near the axle and another above/near the top triple. Now stand on the pegs and look down over the front - if the straight edges do not line up you know you have a bend somewhere.
I have straightend lower triples before so if you find this is the problem let me know and I'll give you the details on how to straighten - but the best fix is to replace.
So....did you check it out yet?
I have been looking into it, but have not had the time to take them apart due to work...however, I just ordered some stands for the bike, and Redline sends out an email with how to care for them and other instructions. One of the items is:
1. 1998-2001 R6's and R1's have uneven front forks causing the handle bars to
sit slightly off center when in use with our front stand, which does NOT hurt
stability.
So maybe everything is ok, and I'm just paranoid?

What they are refering to there is that the bottom of each fork leg is shaped slighty different and since their stand supports the bike from the bottom of the fork leg - the bike's frontend will not sit evenly without being cocked to one side and that it does not effect the stability of the bike while supported by the stand. This has nothing to do with your current problem.
I would not recommend this type of stand as your only front stand. You want one that supports the frontend by a pin that slides into the lower triple/steering stem. This way you can adjust fork height, check straightness as well as tire changes and ect. The type of stand you are refering to is simply good for tire changes.
for an example of the type of stand I'm recommending go to http://www.woodcraft-cfm.com/Scripts/prodList.asp?idCategory=12767
the front stand pictured at the bottom is what you want.
Be careful of some front stands like that though! Though they are good to hold your bike, some dont allow you to get the axle out! :wtf: They are far better than the alternative though! :thumb:
Thanks for the help. I chose this stand just for the winter, so my bike can sit up off the tires. My SV does have the type of stand your are reffering to. I will get this crooked thing checked out some time. The weather is turning cold in Chicago. Not much riding left. Not to mention school and hockey just started back up. Busy full time.

I think you're refering to the stand I recommended. I've never seen/used one that wouldn't allow the axle to be removed. I have used one that required me to point the steering slighty to the left or right to get the axle to clear the stand. Do you know what brand you were using? Did it not allow movement of the steering?

Gottcha, I'm in the Chicago area myself. Feel free to email me at info@serpentracing.com for my phone number if you need more detailed Info.

Thanks guys. You've all been very helpful.
