I trail ride a 98 125 SX. The jetting seems to be very good(no spooge, pulls real clean), but it has the NOZI needle and am thinking about switching to a single-taper. I was wondering what the effect on the delivery of the power will be, and which needle to start with. Also, how do I change the opening of the power-valve on my bike. If so, what change is recommended, if any. BTW, I run 93 octane with MC1 50:1, and the NOZI needle is in the 2nd clip, pilot is a 45, main (I believe) is a 185. Thanks for your help.
