    Agreed, way too low for 6th gear.

    Red Shift 525 Cams are BAD A$$….Zippers have built the best cam for your lazy, hot 96” 6 speed Bagger. It all started with the wife complaining of the heat on her leg from the stock pipes, we all know how hot the ’07 baggers are. So I took this as the OK to do my upgrades. I did my homework first and this is what we (the great sales team at Zippers and me) put together. D&D 2-1 Fat Cat back cut exhaust, Thunder Max auto tuner w/ wide band O2 sensors, Red Shift dual piston cam chain tensioners and the New Red Shift 525 Cams. WOW!!! This thing is blast to ride, great sound form the pipe. Quick starts, throttle response and running cooler with the Thunder Max auto tuner and you will not believe the low end torque from the new Red Shift 525 cams. The cams start working at 1800-2000 RPM’s and are still pulling above 4 grand! No more down shifting to pass for me and I get the jump on my buds with all the big cams waiting on RPM’s…….Thanks Zippers!!!
