Quick question about rust on the front forks: how much is too much? It looks like there is quite a bit of rust on mine but I'm not sure at what point it *really* matters. I know no rust would be preferable but that's not the world we live in.
Seems I can get some non-rusted out forks on ebay but I figure refurbing these would be a better way to go if I can.
Went down the rabbit hole of finding new front forks - not a great hole to go down.
Of course, next to no one sells these new. I did see that you can buy one (just one - not a pair) for something like $1000 from some specialty website. I'll take a hard pass on that.
Alternatives to buying parts is that I've read are using various high grit sand papers to sand down the rust along with maybe using aluminum foil or something unusual like that. I'll probably stick with high grit sandpaper if I go that route. They say that after you remove the rust completely that you need to fill in the spots with something like a JB Weld epoxy then sand down very thoroughly to get a perfectly smooth finish. Which makes sense because otherwise you're gonna put fork oil everywhere or rip up all your seals (or both!). It isn't a permanent fix though and suggestions say that I should also rebuild the entire fork anyway since rust likely got into the fork oil and has screwed up everything anyway. So, that's cool...
I did try to look for ebay parts more thoroughly. At best - really expensive ($500+ for well used - still need that full rebuild treatment!). At worst - okay prices but unknown quality of parts. Many examples of forks being sold were completely bent. (What is even useful from that? It's like selling shattered pistons.) I live pretty close to a reputable motorcycle suspension shop, so maybe they'd be a good resource for sourcing aftermarket parts if epoxy or ebay just ends up being a bad idea. Maybe I'll just give them a call.
After ebay, I went online looking for new forks. Found a forum post at RRZone here (https://www.rrzone.com/forums/showth...ent-Rear-Shock
) that suggested a few brands. I had already went seeking Ohlins. Not gonna find anything there. Wilbers though sells replacement fork tubes and I believe that's what I need. So for $240 I'd get a new set of fork tubes. That's pretty good deal considering everything else seems insane. Pay an extra $120 and they're gold. Neat but not really necessary. What is nice is that the Wilbers USA shop is near where I live too. (Bay Area) Found the suspension stuff here: https://www.wilbers-shop.de/index.ph...d4e997b10d1b92
They say they build custom springs set to rider weight and everything. Neat... I figure I'll need new fork springs though too. But even ohlins sells that, lol.
I doubt the rear shock is any good after 25 years of what not and however many track day events that this thing has encountered. I mean, I am literally thinking that all the nitrogen leaked out of the thing by now. I don't think they're meant to be rebuilt though. So, I don't think I could even take it off and take it to a shop to get it rebuilt since there was nothing in the service manual about rebuilding it from what I saw. Depending on the shop, I might be able to get full new suspension that's adjusted completely for my body weight - or at least springs. That'd be nice! Not holding out there though... again, just want this thing running... but I am looking at the things that are of concern after I get it to that "running" stage.
It's still important to keep an eye on the future past things like it starting. Who cares if it can start but I can't move it, right?! Haha.
