Message: [QUOTE="Okiewan, post: 1468143, member: 16119"] Couple things: 1) Power valve adjustments can't make MORE power 2) A heavier spring will increase the "hit" as it'll delay opening. 3) Fiddle with it too much and you'll risk messing up the port timing 4) Pro Circuit or anyone else for that matter, offers a BASELINE jetting suggestion. It doesn't account for (your) altitude, air temp, fuel, etc. If you happen to live near PC, you're good to go. :) Your best bet is to set the PV per the manual and ride it. [/QUOTE]
