Hello, I went to the garage to do some work to my bike (2004 WR450) and noticed a puddle of oil about 6 inch (15cm) diameter under it just infront of the rear wheel. It appears to be coming from the rear shock? I assume the rear shock is blown and has leaked out a load of oil? I have a fairly good knowledge of forks but have never done any work to a rear shock before. Has anybody ever heard of this problem before and what would you recomend to fix it? Rebuild it, second hand shock? Any decnet upgrades while im at it? Cheers Lennie.
