I put 250ml of 215.VM2.K5 VIBRATION CANCELLATION FLUID per leg in my pitbike forks and oh boy what a transformation!
They feel like pair of good Jap made USD forks of a modern 85cc bike. Super plush on pretty rough terrain, and no wrist jarring on big hits. It feels like a $1500 upgrade but cost me just $25.
They are that good that they make me realize just how bad my DNM rear shock is. And that shock has only done about 15 hrs since it had good silkolene fluid put in there and a proper regas.
I have the China made copies of the 48mm Marzochhi USD forks.
Stage1: Originally they came with the stock china fish oil in them and felt like crap. I never rode on them (lucky) and flushed out the fish oil and also all the metal machine swarf floating inside the forks which eats seals and bushings in minutes.
Stage2: Then I put some good motorex 7.5 wt oil in them and the action was much smoother. But they still had a lot of chatter in the top of the stroke and on big hits they would easily blow through the stroke and bottom out. I ended up with 285ml of oil for bottoming resistance but the ride wash harsh.
Stage3: Flushed/cleaned and 250ml of 215.VM2.K5. Comp clicker on 5 out (was 9) and rebound on 11 (was 7).
If you do put some of this fluid in your forks or shock, then be sure to flush out all old oil using brake cleaner. If your forks are dirty inside, then throw them away and get new ones because 215.VM2.K5 can only go into very clean suspension.
