Fork Issue

[darkember]

Completed my headstock bearing replacement without any real issues. When I took the bike out for a test I noticed the forks are marginally off, ie: I'm off center to the right and now the throttle side touches the tank. I have spent the afternoon twisting the forks round the bottom yoke lining up the punch marks on the top adjusters to their original positions but I am still off to the right. The forks when they were removed have not been dropped, hit or miss-handled so i'm at a loss as to why they have gone out of true.

Is this a common problem when forks are removed & is there a solution to getting them true again?

Is that your bike in your Avtar ? If so your running a superbike bar conversion?

Does it use a VTR top triple clamp or something else?

Have you actually measured the fork stanchions to know they are straight? Or just assuming because your not aware of them being bent or in an accident that might have caused that?

Think I have got it sorted by using Hawkes method working from the wheel up. Anyways have had a guts full today. Will keep you posted as to the outcome.

Got a link to the method you used dude?

Can't lay my hands on it but as far as I remember:

With the top yoke removed & the bottom yoke loose, work the forks until you are able to slide the front axle into both slider housings without any effort. This is done with the front wheel removed. Then torque up the bottom yoke & work your way up. Remember to torque down the stem nut first before torquing the top yoke pinch bolts.

To torque the wheel up follow the following:

I took it form the owners handbook which shows you how to check the caliper clearance to the disk which should be 0.7mm. (Not the pad to disk clearance)

The sequence is as follows:

1. Insert axle, axle bolt should be on the left side as you are facing the bike.
2. Tighten axle bolt to specified torque.
3. Tighten axle pinch bolts on the RIGHT side to specified torque.
4. Install both right & left calipers & tighten fixing bolts to specified torque.
5. Lightly set the pinch bolts on the left side.
6. Operate the front brake & pump the forks several times.
7. measure clearance between LEFT disk & caliper body (not brake pads) with 0.7mm feeler gauge.
8. If it inserts freely tighten left pinch bolts to specified torque.
9. If it cannot be inserted then pull the left fork out slightly until the 0.7mm gap is achieved before tightening the left pinch bolts.
10. Recheck brake operation & that wheel rotates freely.

NOTE: when tighten up the pinch bolts for each triple clamp, to only turn each bolt one-half turn at a time alternating between bolts so you don't twist or deform the clamp or stanchion Also, never over tighten the pinch bolts. You can cause stiction if you over tighten. this is one of those jobs a quality tq wrench really is a good idea.

When replacing the front wheel, first insert the axle and just hand-tighten it, then finger-tighten the axle pinch bolts. Put the motorcycle back on the ground and bounce on the forks several times to ensure proper axle alignment. After a few bounces, properly torque down the axle and the axle pinch bolts.

Hopefully your getting there now
