foam bumper on '92 CR 250

[slo' mo]

pardon my ignorance here, I am usaully too intimidated to post in this forum, but since I was able to replace fork seals I was actually thinking of having a go at rebuilding the rear shock on my CR250. It's a 1992 and what started me thinking was the foam bumber seems to be decomposing. No leaks on the shock right now but I hate being intimidated by it.

1) can the foam bumber be replaced w/o removing the shaft first?

2) is a shock rebuild something the average "joe mechanic" can do?

3) does it require specialy tools?

Thanks in advance.

The shock is actually easier to service than the forks-however you need a N2 setup(or gas it at a local friendly dealer) and you need to bleed it well. www.mx-tech.com has a rebuild guide on the download section.You need to completely dissassemble the shock to change the bumper and will need a bullet (www.recetech.com sell these-not expensive)to refit the seal head over the shaft without tearing the seal.
