a while back, i serviced my MX Comp Bombers - did a basic oil change and seal/wiper replace.
since doing that though, they are sticky (stiction i think its called) when compressing/returning.
they arent nearly as smooth as they were when i first got them. they needed new seal wipers as the others had perished, soooo....
what gives?
i gave them a while and have since built up about 6-7 hours riding on them but they haven't smoothed out at all.
i took them apart again last night, added more [Stendecs] lube to the wipers (they did look a little dry), checked the bushes and lowers, then made sure the correct amount of oil and weight of oil was used (125ml 7.5wt) and pumped up to 50psi.
now, they are 'improved', but STILL sticking. so im at a loss as to what the problem is...
can the wipers really cause this amount of stiction? (it was a genuine set of Marzocchi wipers and the size is correct)
it means the forks arent soaking up the little bumps - and when riding it feels like the hub is loose (it isn't) but thats the only way i can describe the feedack from the stiction travelling up the fork legs into my handlebars.
the only other way to describe it, is like a lubed/slightly loose fit seatpost moving up and down the seat tube - thats how it feels when you compress the fork for the first time after leaving it sit for a few minutes....
anyone else experienced this?
i'm due to take the bike out again soon, so will give them a second chance to sort themselves out with a good thrashing down a bumpy hill....but even after a Brighton Big Dog run, they hadn't loosened up....
