Transmission Pulley change on a 2007 FLHT with a Champion IRS Trike Kit.

My stock 2007 FLHT came with a 32/66 pulley arrangement. I believe Champion uses the stock rear pulley size that originally came on the bike. That's why Champion offers a '07/'08 kit and a separate kit for 2009 and above. My conversion has an EFM Autoclutch and it does not like starting on inclines while pulling a trailer. Anyone have firsthand experience going with a 30 tooth transmission pulley on a 07/08 triked FLH? Thanks.

I had a 2007 Police RK with a straight axle Champion kit and they recommended a 70 tooth on the rear. I had the 103 motor with 510 G cams stage one cleaner and true dual exhaust. The 32/70 was perfect as far as I was concerned. Dyno ed out at 103 HP and 108 torque. Now the IRS might be different.
