How to check for bent forks was created by XL777
How do you check your forks if they don't look bent but you think they are. I noticed when I was riding my bars were not on center when going straight. So I got looking tore off the lights, and cluster and everything seems straight except the wheel is off angle just a bit. As well there seems to be a 1/16 inch play in the wheel is that normal or should I be looking at new bearings.

It is easier to say what I haven't replaced then what I have.

Your forks may not be bent. They might need to be aligned.Have a manual? It should say how to align your forks in there somewhere. Basically, you loosen all the bolts clamping your upper fork tubes. Loosen them just enough so they can move but not enough that they drop. Be careful on this part...you loosen too much and the tubes will drop and slide up through your trees and the bottom tree will slam onto the front fender-you don't want that. Once you have them loosened up, use your handlebars to twist turn the front end while holding the front wheel til you can visually see they are aligned. Once you think you have them right, run a straight edge along rear tire towards the front to see if the front wheel is right. Look for same distance on both sides of front tire to the straight-edge, or whatever you can come up with to give you an idea of where front wheel is sitting. Once you have them aligned, tighten the bolts back up. I have run into this before where the bats and/or front wheel seemed crooked and this took care of it. Doesn't take a lot to cause top tree and bottom tree to twist out of alignment a little and cause this.

That make sense, they seem to twist quite easy. I will have to get afork brace. what about the play in the front wheel? It seems to move more then it should

Shouldn't be "any" play in the front wheel.
Check the wheel bearings.

That is what I thought. Would a bad bearing allow that much play? I'm going order some from Z1 ASAP, but I can't seem to find any replacement grease seals on their site. Who carry's them?
