Oh I took out a 150 so I thought that the stock one was a 150. I guess it was messed with prior to me getting into it. Thanks for the info. So I guess Ill be running one up on both the main and the pilot.
The stock in my girlfriend's was 145, so I installed a 150 main and went up one size on the pilot to 45. I opened up the air box and put in a UNI, runs stronger now. I just installed the pipe, but haven't tested it yet. Also changed the stock 22" balloon rears with some flat 20" tires, we'll see how that feels. Working on suspension right now.
Took her for a quick spin today and boy does it feel better. Better throttle response and acceleration. I put Banshee shocks on the front and 2001 Raptor 660 shock on the rear, ride and handling improved.
