How many teeth are on the front pulley/sprocket? I have a 2009 FLTR and I'm not sure where to find this info with out taking the bike apart and counting them.
Awesome. Thanks.The 09 and later touring models have 32 nubs in the front pulley and 68 nubs in the rear pulley.
08 and earlier have 32 nubs in the front pulley and 66 nubs in the rear pulley.
Just the opposite. I just went to a 30 and see an increase in rpm. Approx 300 more at 70 mph. Definitely feels like more power down low when pulling out. I like it.Awesome. Thanks.
So, if I go to a 34 front, I'd see an increase in power. If I went to a 30, it would be less power, but better on fuel. Right?
Great info... Thank you!More power and less top end by dropping a few teeth. Less power and higher top end by adding a few teeth. Dropping to a 30t front pulley adds about 7% more torque increase and rpm at any given speed. You can do the math on that depending on where you ride.
I ran a 30t front pulley for a few years. Just barely switched back to stock. I switched back because I have plenty of power in this new motor and I wanted a more relaxed ride at speed and don't need the additional torque. The 30t pulley is a great mod if you are fine turning a higher rpm. You will need a 139t belt (140t is stock). Harley doesn't have a 139 belt and so you will need an aftermarket belt. Gates PolyChain is probably the best out there. You can mod your swing arm and run the stock belt but that requires welding in a gusset and spacers and then die grinding out the axle shaft bore larger. Personally I felt that changing out the belt was the better option so that I could easily go back to stock.
