300 TPI Idle Screw Mod

Decided to try my hand at this surgery on my throttle body. Fairly straightforward job...if you have patience. Heating up a $1000 throttle body on a 2 week old dirt bike is a little intense...but doable. Now, with a proper idle screw, 300 TPI owners can adjust for air/fuel with the air screw, then set idle with the idle screw mod.
