i have a 2005 banshee that i put t6s on. its got a 280 main, stock pilot, and needle on the fourth groove, and air screw one and a half turns out like toomey says. the bike pulls fine up untill 5th gear, but will not rev in 6th like it used to, i used to be looking for a 7th gear with the stock pipes, now it seems like 6th is too high a gear. i ride at sea level, in the winter, it can be 20 degrees F. and in the summer up to 85. i have a booste bottle, boyesen reeds, and a 4 deg. advance timing key, and the toomey 2:1 intake with a UNI filter. any sugestions on what i can do to get more top end revs???????
