piston question

[Jeremy_bell_banshee99]

Looking on a 2 stroke tuning site for my dirt bike, it recommended i take a edge off the piston where the exhuast port is, if i did this to my banshee wouldnt it be about the same as the superstock piston?

The super stock pistons are 1mm down

Super stock dyno piston results are in the dyno section in the random dyno discussion post.

So itll be a nice gain in performance? I can just mark then take the dremal tool and chop away? Ill practice on old pistons first of coarse

i am curiouis is the top ring is lowered on the superstock pistons to keep the top of the piston from pushing down onto the ring.. anyone able to do a side to side comparison?

I would also like to see a picture. I have a older cr 80 and if it's something free and can add power then I'm all for it

Sheerider11, its called the two stroke performance tuning. Its a basic porting, jetting performance tuners guide. I have pics i will upload tomorrow

Gorden Jennings Two Stroke Tuners Handbook. If you read it closely, this is a method for "Testing" a given port timing to see if it's what you want. Vito's pistons are made with the rings further down to accomadate the cut.
