You really need to ride it hard 1st. Clean out all the crap inside the power valves and pipe. Being 1.5 turns out will help. Of you adjust the air screw while it runs and the idle improves after more than 2 turns of the air screw you need a leaner pilot.
It runs way better now. Ill take it for a rip once i get some new gas. Is it okay to combine a bit of the 87 with 91? Like 3/4 91 and 1/4 87
