Has anyone serviced the 450R's factory front shocks? I don't race so I don't need $1000 new shocks. I just want to change the oil, replace the seals and re-charge them. I have rebuilt many piggyback type dirt bike shocks, but I can't seem to get the seal protector off the shock body on these 450R shocks. Also if anyone has a favorite oil weight for these shocks that would help too. I have 5wt & 8wt on my shelf now. Thanks E.
