Ok no that I have me rebuild I am bored out to like a 407 with a 10:1 compression piston uni air filter stage 2 hot cam and I am at about 275 feet above sea level in new York I was wondering if any one might be able to get me in the ball park on what my jetting should be

Judging by the jetting in your sig you are pretty close to where you need to be already.

If you want to be 100% sure, try a 170 or 175 main jet, as long as your not stuttering on the topend you wont be to rich.

If your not visibly running hotter or popping and backfiring you might be fine with what you are currently running. My best advice is to get a infra red "laser" temp gun and monitor your temps after a few runs, if you get over 210-215 after a hard run, try a bigger main jet and see if it goes down or not.
