3pg performance mods

[Charles M]

I am thanking about doing the mods to the top end of my 3pg motor that theGDFP did for Bikertrash00. Has any one else done this to there motor and how was the performance after? I am thinking of actuality going in and porting the cylinder so I would not have to build the spacer and cut the top of the cylinder. Also putting the 88 carb on it and changing the ing. timing. Any suggestions?

Yeah BE CAREFUL! Porting any motor, 4 stroke or 2 stroke, can add performance, but if done incorrectly can reduce performance WAY more than you would think. I do think (don't "know" but do believe) that 2 strokes are even more sensitive to porting than 4 strokes. So when in doubt, do less.
Good luck, when done right I know it can make you very happy! When done wrong, you need to buy a new cylinder, so not the end of the world, but still!

I have done 2 strokes before the port timing is what makes the difference if I do port the motor will start with the degree wheel . It is just like changing the cam in a 4 stroke . Am looking for some suggestions on port timing.
