my bike was running rich at the top end (mains were too big), but i was too lazy to take the carbs apart to adjust it, since the bike ran quite well in the lower/mid range, which is what i drive in 80% of the time.

after porting it, they adjusted the jetting correctly, and yeah, gained a significant amount.

im using a sportisi jet kit, that comes with 40 pilot jets, adjustable needles, and a lot of mains to choose from~ i forgot to ask what mains they ended up using this time. its gonna change again shortly, since the bike will get the new pistons, and will have to get re-jetted again, lol
