I have a 4mil passion 12 port motor. The problem is when i leave in 2nd gear it seems to bog when its hooking decent and i have to clutch it to get it back on the pipe. Im running 14-41 gearing and 20" duro hook-ups that hook really good. As long as i leave in first gear it does not bog in 2nd but i thought it should pull second really well with the power it makes. Plug looks great and jetting is what jim at passion recommended which is 152-50. I was wondering if leaning the pilot jet would help or do you think it should be geared lower when track is hooking? Here are the specs of my setup.

35pwks 152-50 jetting, close to sea level
