I am new to the 2 strokes and have read on jets but I am getting my cylinder back from KOR and don't want to chance messing it up. My bike has a fmf fatty and power core 2. I think boysen reeds and a k$n type filter with the lid on. I am at 2400 ft. and its in the 30-40's right now. It has a 230 main in it right now, don't know the pilot. What should I start with when I put it back together? I want to make sure I don't heat cycle it lean. What should I start with? I will plug chop after a couple tanks of gas. I think the 230 is too lean from what I have read. Thanks.
