Ordering a new spring for the rear shock, so I figure I may as well grab a gold valve and set my valving up at the same time.....hoping to get a couple questions answered as the manual just says to toss the shock if you don't like it...ha. I have enough experience rebuilding shocks and forks....so i don't see why I would have any issues.... - does this shock use a seal head? Or a stand alone seal? Racetech shows a seal part so I'm assuming the latter. -by looking at the reservoir cap I assume I will use the motion pro needle setup I purchased for adding nitrogen? -is the correct process for bleeding the existing nitrogen simply to insert the needle and let it bleed out? (I ask because the raptor shock I originally used this on didn't need any bleeding as the nitrogen had displaced itself which caused the rebuild in the first place) -anyone have a good baseline for the nitrogen fill?
