Help with part numbers

Getting ready for winter upgrade season. I currently have a 2011 Streetbob. I already have Heavy Breather, V&H Big radious, & SERT. Going to be installing Stage 1 103" and 255 cams that I bought seperately. Will I need any additional parts for that install? Also if money permits I plan to add the andrews 30T pulley and the HD 70T pulley however I can't seem to find the part numbers for the appropriate HD pulley in black and for the appropriate belt...

Thanks

you won't have to change the belt and don't buy the Andrews pulley buy the 30tooth HD Tri Glide pulley.......it's quite a bit less expensive

Your original 66T sprocket for a 2011 StreetBob is part # 40114-07, so I'm pretty sure that a mid-2000's Dyna 70T rear wheel sprocket will fit your wheel.

Part # 40114-00 is a 70 tooth sprocket for '04 FXDX. They both use the narrow belt, but the number of teeth on the belt is different.

Your original belt has 131T…the belt on a '04 FXDX has 133T…not much difference. You're gaining 4 teeth on the rear sprocket, and losing 2 teeth on the tranny pulley with your new configuration. You should be fine. I would at least try your existing belt before dishing out $200+ for a new one that you more than likely won't need.
