Since the rebuild i have noticed a definate weave at speed from the front and on turning it feels like the front wants to push away from me leaving me with little confidence on the front.
Now i have to ask myself have i done the forks correctly? is ther too much fork oil in them? are they set to hard or could it be the tyre?
BT56 on the front and spins true and fine, guess i will have to wait until it is dry to really test it but i think something may be incorrect with the forks so will have to get them done properly this time and see if that solves it, cheapest option i guess first off at Â£35.

keep ya posted or any input greatly appreciated

Are the headbearings ok?
Did you get that front wheel rebalanced mate?
Wheel had new bearings fitted not so long ago so wouldnt be them.
Whats the tread like on the BT56, has tyre started to step?

no mate headstock is good, bearing fine and regreased, tyre is fine,
what im thinking is this, if i have put too much fork fluid in and have the compression wound in to far is this making the front end too firm and wanting to push the wheel back out on cornering ? im new when it comes to doing forks and this was my first attempt.
im quiet sure i have too much fluid in them, so would this cause them to want to push the front end away on cornering? it certainly does not feel planted and safe, i will wind out the compression to it's softest to see if that makes things a bit more stable.

Did you check the yokes are straight

yes mate, yokes survived so i will get the forks done proffesionally and see if that sorts it, failing that 929 front end, actually im already searching for it lol !

First things first before spending any money

Set-up your static sag and rider sag as described in the post at the top of the workshop section also set-up your damping to the standard settings if things donâ€™t improve then move on

Check every thing
Is the oil level ok, was it set with the forks fully compressed and the springs out, have you used the right weight of oil, have all the spacer tubes and shim washers been put back in there original positions.

If you have checked all the above youâ€™ll have the bike with the springs out and supported under the engine then remove the front wheel and move one fork at a time fully up to fully extended is there any binding is every thing sliding smoothly
Is there a lot of air in the oil when doing this?

Remove the o seal from the fork top bolt so air can escape drop the damper adjuster rod back in to the fork no spring donâ€™t tighten it right down you want the air in the top of the fork to be able to escape then lift on fork at a time and check the damping is working ok it should be a lot harder to extend the fork than to lift it there will be some spring effect as the air is expelled
If thereâ€™s no problems found then have some one else look at them for you

This little lot should take you about an hour to do and could save you the Â£30

When you drained the forks, did you make sure all the old oil was out, by pumping them a few times to expel any residual oil through valve?

If not then as you say, you may have more oil than you should.

Also make sure you center the left hand fork leg before tightening the clamp bolts on the wheel spindle. To do this you need to fit the brake caliper's (if they have been removed) and apply the front brake a few times as well as pushing the handle bars up and down to center the fork leg, then tighten the clamp bolts

The righthand fork leg clamp bolts should already be tightened and the wheel spindle before centering the lefthand leg.

HTH,

Chris.

No truck mechanic
they dont have forks

Post by **kevg** » Sat Jul 19, 2008 10:12 pm

bit of an off the wall sujestion but are the tires on the right way, i had a rear on my old bandit fitted at a garage on backwards and the bike weaved like a bitch, looked at the wheels, bearings and noticed the arrows on the tire were the wrong way round, took it back to the garage and changed direction...job done, handled fine after.

fork trucks do

Fork trucks do

The idea is to try out the forks to see if thereâ€™s any obvious problem with free movement and damping before pulling them of the bike and shelling out to have some one look at them

If you can see a problem with the way Iâ€™ve put some thing let us know some times I what looks ok to me can have others stepping back and going what the hells he on about

And Iâ€™ll try and reword it

sorry to jump on the thread but you guys will probably know this. Can you fit the blade RRX forks straight onto the storm.

i.e. are they the same diameter legs as the storm and will they take the same brake calipers? I don't think the mudguards fit but I can live with that for a while.
