just like the title says, when i rev my bike up it seems as if it the rpm's tend to hold itself their for a second or so, then the rpm's come down. anyone know what causes this? much help appreciated

Usualy caused by a lean mixture.What size pilot jets are you running, & what are your mod's...All of em.

im pretty sure my jetting is 160 155 mains with 25 pilots and screws set at 2 or 2 1/2 turns out. my engine is a stock bore rebuilt with prox piston, yoshimura pipe and k&n air filter, and a carb spacer

Turn your fuel screws out (ccw) another 1/4 to 1/2 turn each - hanging idle is due to lean pilot setting... the fuel screws adjust the pilot mixture.

Have you messed with you throttle cable lately? If you turn it all the way does it rev up? I had this problem and had to reroute it again after I messed with it.
