Noticed yesturday that the nearside front fork seal is weeping oil.

Anyone replaced these, if so is it a big job, any tips.

Thanks - Steve

Ah ha....... I did these quite recently Steve, and they're not as scary a job as you'd think. You'll need a low torque wrench if you're worried about that sort of thing, and you'll need an open ended 21mm ring spanner + a 7mm hex socket to remove the front UJ on the suspension. You might also have trouble removing the little 5mm button heads that hold on the front brake pipes to the lower yoke.

Once you've got all that off, then you can just undo the bleed valves at the tops of the forks then pull the tops out. Carefully lever out the old seals - then pour in the new oil (top tip - get a 100mm syringe to measure it out accurately - I've got one + a load of fork oil spare if you want some). Slide in the uppers then put the seals over the top and tap them in (top tip No2 - put a spare metal fork washer - I've got one of them - over the seal to protect it then get a length of 40mm bathroom waste pipe and fit it over the upper then bang it on the end to push the seal into the lower - easy as pie)

Has your bike got a centre stand Steve? Hope so. The seals are only cheap and it doesn't take as long to do as you'd think. If you want to borrow anything then let me know.

Many thanks for the info.

Will go buy the seals tomorrow and try and fit them on Monday.
