SandShooter Posted February 11, 2007 Report Posted February 11, 2007 I have a queston about piston weights. I had to replace one piston. The new one is 10 grams heavier then the old one. They are both Wisco prolite. My original piston is perfect, didnt really want to have to replace it. Is 10 gram diff on the pistons something to worring about? Quote
CadillacBanshee Posted February 11, 2007 Report Posted February 11, 2007 I wouldn't recommend changing just one piston. Change them both to new ones and dont worry aout the weight. Did you measure them both without piston rings? david I have a queston about piston weights. I had to replace one piston. The new one is 10 grams heavier then the old one.

SandShooter Posted February 11, 2007 Author Report Posted February 11, 2007 I only replaced the one piston because it only has maybe 3 or 4 trips on it when I burned a hole in one of them. I measured the weight with no rings just the bare piston. Quote
FireHead Posted February 11, 2007 Report Posted February 11, 2007 Matching the weight of the pistons is very important in racing engines where there ary very high tolerances ans you are trying to squeeze every last once of power out of the engine. In most cases with a Banshee, it probably doesn't matter. If I were you I would replace both pistons at the same time especially since your old piston is 10 grams different from your nbew piston, which leads me to beleive that it is not in as good of shape as you think it is. :thumbsup: Quote
