I got 3 different thicknesses and measured them and used the same thickness as the old one, dont remember the measurement tho. I only rode the bike a couple of times, mabye 2-3h, before changing the piston and going over the bike. At that time it was geared 12/48 also. I can?t really remember how it ran more then it was a bit blubbery and rich. I rode the same jetting as the old piston the first time I rode the new piston and I recall it running better then. But I also ran more open space at a higher speed so it might be a oil/spooge thing going on. The low torque bottom end started with the old jetting also.
Thanks for the jetting info. Its strange to me that I need to go down in pj size even in the cold weather. Snow riding is great! With good studded tires its often more grip and falling is soft
