The crankshaft is modded and coated.
Piston/sleeve is modded same as old RS an NS based JP's
And if you have the money: CERAMIC bearings
Found this in the JP FX Forum from daniz24 wich is super modded by JP himself:
Super-modded how? Deeper grooves?
I noticed that there isn't a mid-range needle adjustment .. this is the 3-port right?
A 5-port one is also available at rc-mushroom.
