Thanks for the info. There's a lot of confusing part numbers out there. I already have the 30 tooth pulley but had to use a shorter belt. Hearing some of the stories about belts, I want to get in range to use a stock belt. Speedo error taken care of with PV. The 30 tooth made a huge difference. I think the 68 tooth will make a small difference but allow the use of a stock belt. I don't cruise much above 75 (too old and not in a hurry), so the rpm shouldn't matter.

If you already have IDS can you use the hub you have and just get the correct sprocket ?

 

Yes. You need the 68T Japanese sportster pulley and the axle bearing for your 07 IDS application. I did this mod to both my 08's.
