I think its time to freshen up my forks on the ol YZ. I purchased the bike used and have no idea when this was last done. I am only going to replace the oil since the seals are still fine. My question: what weight oil and how much should i put in? Mostly ride mx and some trails here and there. The previous owner had it revlaved for his weight(we weigh the same), but he primarily rode enduros and cross country. The front seems too soft esp hitting larger jumps. Should i get it revalved again or would thicker oil help a bit?
