I PUT A SIZE 45 PILOT IN ALONG WITH THE OTHER RECOMMENDED 138 MAIN SIZE 9 PLUG ECT. TRYING AP MOD TODAY. ENGINE PULLS HARD AT WOT. WON'T IDLE RIGHT WITH POPPING. IS IT POSSIBLE TO NEED A MUCH LARGER PILOT LIKE A 50 OR 55?

No. Try opening up the fuel screw a bit.

Tried it up to 3 turns no change. No air intake leaks. All new head work. Throttle position sensor tested good. I run 50/50 race gas and a 13 2 1 piston. The bike has done this since new. Trying larger pilots. If that's not it. Must be ignition. Any more suggestions is greatly appreciated. Thanks Agent
