i did the head port polish , 10 3/4 piston bigger valves and stud kit and mudbuster cam stage II (( still 660 bore)). It made a little difference but not as much as i hopped the power is now good from bottom end to top and on the dyno the power curve is almost flat. Before the mods it would peak then fall off. I still have a stock carb , single FMF muffler on a stock pipe with a intake that is outside yhe engine compartment with a uni and a 205 main jet, and it run 13 to 13.5 with the mass air sensor

thats my two cents
