    Fork dilema

    I had my fork seals replaced a few weeks back and a week or so later I noticed they have begun to slightly mist again due to mild pitting on the stanchions. I revisited the bike shop where I had them done and they agreed to replace the seals but said they could only do this once under warranty.

    The guy told me the best bet was probably to replace the stanchions or get them re-chromed and he said he'd fit them and the seals (also without charge) under warranty but obviously I'd have to pay for the re-chroming. He told me he has acknowledged the problem but to wait for now and see if they get any worse and then have a think of what I wanted to do. He said I may get lucky and they may bed in and not get any worse. However, due to the shitty weather here over the last month I have not done many miles on the bike since, so they have not changed in status but, I know deep down, it is only a matter of time before they start to deteriorate.

    Having looked around the web I'm not sure what to do. The guy told me that re-chroming would cost about 100/$200 but I have read that re-chroming stanchions can give mixed results. Looking at prices to replace the stanchions it comes in at 170/$345. For the extra 70 I guess I should go for the replacements but I'm now wondering if instead I should look out for a new complete front end. What sort of price can you get a complete alternative front end for?

    I have read about applying clear nail polish to the pitted area and rubbing down with 3200 grit wet and dry but I'm not convinced this is a lasting solution. What would you do in my position?

    A couple of things :-
    - Your mechanic may be a nobhead and have arsed up the fitting of the seals. It happens, I've done it myself once. Of course getting him to accept this might be a problem ...
    - Pitting doesn't help. I've used the araldite (rather than nailpolish) method myself many years ago on an old rat bike - it works.
    - I can't comment on rechroming, never had it done. There's a place that has advertised (Philpotts?) in MCN for years that surely must be good on longevity alone. Expensive, as you say.
    - A complete set of second hand forks prolly go for 50-70 on eBay. Of course you may have to wait for an undamaged set.

    If it was me I'd prolly do as the mechanic says - keep 'em as clean as possible and see if it gets worse.

      Thanks for the feedback, Al. I'm gonna buy some epoxy this weekend and try to fill and sand the larger pit. The more I think about it, the more I remember soon after I bought it and was cleaning around the forks when I scraped what I though was a little debris from one of the legs and suddenly I noticed the larger pit. Days after that my fork seal first started to leak. I have a strange feeling this may have been filled before and I went and scraped it off, not realising it was a fill. Oh well, we'll see.

        Hopefully things all went well over the weekend with your efforts Swipe.

        "- A complete set of second hand forks prolly go for 50-70 on eBay. Of course you may have to wait for an undamaged set. "

        Yeah this is about right. I missed a really nice set of F2 '91 forks on Ebay over the weekend - got outsniped in the last second and they went for 52.00. /sigh

        There's a pair of NTV forks coming up, which might go very cheap Swipe:

          Yes, I was watching those F2 forks too Ribbit, but I wasn't sure about the Bros calliper attachment and also if the Bros spindle would fit the legs. Anyhow, I have had a go at filling the pits and rubbing them down and they seem smooth now. I have done another 120 miles over the weekend and the misting hasn't seemed to deteriorate and there seems to be slightly less so I'll keep my eye on it for now. I'm hoping what i am seeing now (very minor misting) is just the excess oil from before.

          Does anyone know if the uppers on the Bros 400 are exactly the same as the 650's as I have seen a site that charges 4 more for the 650 ones

          Thanks for the ebay link btw, I'll keep my eye on those NTV ones and may put in a bid if they are still a reasonable price at the closing stages of the auction.

            According to these people:

            http://www.lm-spares.co.uk/acatalog/...Fork_Kits.html

            length is identical whether the 400 or 650, and part number is the same (117) even if the price isn't.

            Seems an awful lot of money for steel tubes, and they want to put VAT on top as well (should include VAT, and new springs, for that sort of money, imo, hehe).

            Heck good straight Kawasaki 7R USD forks went for less than 25% of that price, yesterday morning (I overslept ).

              The mounting is different.

                Hey completely off topic (apologies for which), either of you tried the tyre that Continental recommend as fitment for the Bros, the Avenue?

                I'm starting to sweat about the rapidly approaching Autumn, given I am still on 18 year old original fitment tyres (and the darned tread seems to be growing rather than wearing out!).

                I can't manage suspension, brakes, tyres, and a seat, at the moment, and I have a chance of a nice seat that'll suit me perfect.

                Given I haven't found any mention of Avenues in a forum search, and I would likely wear out a set before next spring (most of my biking is done in the Winter, believe it or not - suits my clapped out eyes better), I figured I might as well give them a shot (cheap too! which will help me get an exhaust sorted maybe) and then be able to give some feedback on them here.

                If I get the seat, I can get the tyres in September before everything goes pearshaped with all the leaves on the roads, and if I can get my hands on a 2:1 collector, I can get some sort of a weird and unusual heavily discounted can off the family for Christmas.

                  Mine has avenues but i'm changing the rear for a 160/60 roadattack, 10 quid more from m&p ...The aves were ok but there are better tyres out there and they have a sexier tread pattern!

                    Thanks for the feedback on the Avenues Guzzisti.

                    Aye I was thinking of doing something similar, but am wary about having a more grippy rear tyre than there is on the front?

                    Another option would be Contiforce, if the 110/70 x 17 would work ok on a standard front rim?

                    Set would be about a tenner more than the Avenues (115 from Busters), and I've seen the Contiforce in action a lot, as a friend used them exclusively on his Suzuki Bandit, and they were impressive (he's definitely a fast mover). I'd probably get though 2 x rears and 1 x front of the Contiforce through the winter though.

                      I am going to contact Fuel exhausts and see if they are prepared to sell the Y collector on its own. I know others have tried in the past but it has got to be worth a shot. Maybe if we can rustle enough orders on here they may accommodate us, so I'll ask if a bulk order may change their mind. I can understand why they are reluctant, as I suppose they think along the lines of selling the Y collector on its own is a sale lost on one of their muffler cans.

                        Hey count me in Swipe, great idea!

                        Tell them it's a South American racing team looking for a season's worth of collectors, and they'll probably take 10! *giggles*

                        ETA: Hmmmm, just had a thought. The ideal person to contact them would be someone Stateside, and have one of us as the delivery point to take them over for them sorta thing (or heck it wouldn't be a huge expense to even get them shipped back individually would it?). I bet there *would* be interest in them among the Hawk racing community. Doc/JD should know?

                        What is nice about their 2:1, is it seems to be pretty long, so has a lot of room for manouvre for bending and shortening?

                        Heh, I even PM'd Doc earlier to see if he had an old collector around the place he wanted to sell.

                          Just emailed them before I saw your edit. I told them I could rustle up enough interest for a small bulk order. Lets see what they come back with.

                              Im running dunlop qualifiers 160/60rear 110/70 front this effectively lowers the front and rear the same amount 10mm(Very Very important). Ive put 7000 miles on them and they are great!!!!!! I was using the whole tire with the stock sizes now I have a 1/2" chicken strip and Im still touching my shoe to the ground with the stock pegs. (I'll be putting on rearsets soon)
