how to troubleshoot forks

Im rebuilding my bike as you all know (and thanks a TON for all the help) but now my forks are jacked up. I previously knew this but when i align my triple tree with my frame, my wheel points to the left a little bit. I played around with my forks before i pulled my frame off yesterday to find out that there is no way to re-align my wheel in relation to the triple tree easily. In a previous thread, i asked a question wondering if it was possible for the forks to be "tweaked" instead of bent, and if it were possible to "tweak" them back by loosening the clamps that hold them, align the wheel, then tightening when desired to keep the wheel straight.

Well, after loosening the clamps, i found that my fork tubes rotate freely, removing any possibility of straightening out the wheel when loose then tightening. Am I wrong???

So my quesiton is, now that i have my wheel headed port with nothing I can do about it, how do I go about finding the problem?

IDK if its one tube, both tubes, lower triple, upper triple... and right now i cant be dumping a grip for a whole new front end. I just wanna straighten this BZ up quick, cheap, and correctly.

Any help is appreciated
merry christmas

Keep the wheel together with the forks. Put one leg on each side of the wheel and twist the bars until they are straight with the wheel.

I didn't really understand the rest of your post so sorry if what I just said was like DUH.

thanks for trying to help again dcope, but if the tubes of the forks rotate freely (without restriction from the lower half), when i would straighten the wheel, wouldnt it just go back?

The wheel could be tweaked even when the forks or straight. Keeping them together would let you know if it's the wheel, forks, or frame that is tweaked when trying to straighten it.

Does the front wheel feel loose and wobble back and forth if you push on it?
Got any pics of how it's not straight?

front wheel is completely good, no play no amount of shaking when riding high speeds whatsoever.
The frame is completely perfect too, im actually going to sell it here when i get these forks off...

tomorrow ill take some pictures when i try to further fix this problem... Im getting pretty damn close to getting an 06 front end..

By twisting the bars to be straight with the wheel, you're not twisting each fork slider. You will be twisting one of the triples to help it line up with the other triple.

You may have to loosen the bolt on top of the steering stem also. I don't know, I've only had to do this with dirt bikes and they wern't as heavy duty as my 600. I was able to leave the nut tight and still line it all up.

I wish I had a better way of lining these up that was better then eyeballing it but I don't.

It seems unlikely but it is possible.

Remove the fork from the bike and roll them on a flat surface.
You should be able to eyeball it.
If its tweaked, you will see the problem.
Basically your rolling the fork tube and looking to see if there any bends
If its tweak its going to roll uneven.

If you do this it needs to be on a completely flat surface, like a sheet of glass or marble.

ok after messing with it some more i was able to get it straight!!

After that i put them on the new frame with no problems!

im getting real close to finishing the project, thanks again for all the help :D

Upgrades for the new build:

55w HID kit
520 conversion (+1,-1)
Jardine slip-on
Driven Diamond grips

quick question though-

Since I rotated the tubes of the forks before I tweaked them back, will it effect anything?
