OK I know I need to rejet my blaster. It's an 01. It has after market pipe,silencer, reedspacer, and after market reeds. What's a typical jet size to move to? Also in June I'm doing a charity ride to the top of mount Washington. Do anyone have experience with a 6000 foot change? Will it effect me at all. Thanks!!
 
What pipe ? Any porting ? And what altitude and temp. you're riding at now ?
Pro Circuit pipe. No porting. I'm at an average altitude of 450' temps range from 10- 90 degrees. All year around. I live in the New England area
 
Well if your air box lid is off and you pre-mix your gas ? Winter time I would start with a 300-320 main...stock pilot...air screw 1.5 out . Needle in the middle . Plug chop and go from there . Summer time you'll be around a 280-290 main
