30T drive pulley
#31
+1 on this..... I did this 15K ago on my '09.... puts the gearing where you want it and eliminates all the problems with the junk compensator..... AND you dont have to change drive belts

Do you need a shorter chain then?? What is all involved here?? Trying to find the best way to do this...30t and belt...or primary sprocket??

The concern with eliminating the compensator, is you put more shock loads on your crankshaft. With our press-fit flywheels, we run the risk of scissoring the crank under heave shock loading, which would necessitate a complete teardown and new crank. I'd rather replace the compensator every few years, if necessary, than run the risk of blowing out my bottom end.
It's not that hard to change the trans pulley. I had a 32/66 final drive a couple of years ago. Last year, I switched my wheel pulley to a 68t one from a Sportster. That put me at the same final drive as the 09-newer bikes. Still not enough, so part of my off-season mods was to install a 30t trans pulley from the tri-glide. The 30/68 secondary drive gives you a 3.07 final gear ratio, still a little taller than the old 5-speed bikes (3.15). This seems perfect, to me, I get good acceleration in every gear, and still cruise at low rpms (2800 at 70 mph, about 200 rpms higher than it was with the original gearing).
I would not go back.

I've been looking for a sprocket for my 2010 wg to do this same mod and can't seem to find one. Is there one out there to replace the stock compensator on these bikes? Does this require a different primary chain with the swap? I would much rather do this over the 30t drive belt pulley swap.
