can any one offer any advice?
I have recently replaced my fork seals only to notice this morning that they are leaking again. The fork tubes were a little pitted, but it didn't feel like they were bad enough to affect the seals.
so, do I try and replace the seals again, or look to replace the forks?
is just changing the tubes for some new ones better than getting an unknown set of folks off ebay?
If I look on ebay, will different years fit on my 1994 Diversion, if so, what years or models should I be looking out for?
cheers,
Michael

If the edges of the pits are sharp, they will tear the seals. You could try very light stoning to smooth off the edges. Alternatively the tubes can be reconditioned and re-plated which should make them better than new.
The forks changed when the twin disc brakes were fitted in about 1997 (I no longer have a Haynes manual so can't check that date).
So if you are looking to buy second-hand, make sure you get the earlier single disc version.

cheers bobh, the pits do have smooth edges, checked them before I re-assembled them the first time, but still no joy. I'm watching a used set on ebay, so hopefully they'll not go for silly money and I can win them, and they will be a better replacement.

All early divvies with the single disc had the same forks, so any of those will fit. Might be tricky finding a set better than yours, and straight.
A decent bodge is to degrease about 5 times, then smother in araldite, then smooth with very fine W+D. Degreasing very well is essential though or it won't take.
Is it possible you damaged the seals on fitting them?

possibly, but I have ordered a "used" set of ebay, and just waiting delivery of them now. The seller did confirm that they were not leaking, son fingers crossed...

Finally I have managed to sort out my fork seals.
After fitting a first set of seals, then buying a replacement set of "used" forks off ebay, then replacing those seals.
What I did to finally resolve it was to buy proper Yamaha fork seals instead of cheap ones off an online spares web site.
I also borrowed a seal driver tool of Yamaha which made fitting them a doddle.
Thought I'd share this with everyone.

Though Vesrah ones haven't let me down - a little pricier than the cheapest, but not quite Yammy OE prices. Readily avail on Ebay etc. |

TBH the Yamaha ones were not very expensive at all, and the amount I have wasted on oil and seals, I wish I had used them first. oh well, live and learn...
