question about FXR chain conversion
I am helping a buddy do a total rebuild on his 1988 FXR. He is installing a S&S 124, baker tranny, evolution industries clutch basket , compufire starter, compensator, rear shocks, inverted front end with radial brake calipers and other parts. He wants to do a belt to chain conversion. But he cant find a Supersprox stealth sprocket for an FXR. One of his upgrade will also be a new aluminum swing arm. He wanted Roaring Toys but they dont show an FXR on their website so he may go with a Brocks Performance.
If he ordered the Brocks swing arm and clicked on the axle size for a 2011 Dyna. And got an inverted front end also with the Dyna axle size. Then bought a front and rear wheel to fit the front and rear. Could he technically get a rear Supersprox stealth sprocket and mount it along with a spacer for a Dyna? If he did that what front sprocket would he have to use? Would a secondary front sprocket that is for a Dyna fit his FXR? I did a chain conversion on my Dyna when I installed a S&S 124. But I pretty much changed everything on my bike. The only thing stock on my Dyna are the frame, tranny case (i have the baker grudge reverse shift) Tins , main wire harness and swing arm which is being swapped for a Roaring Toyz next month. But I dont know much about belt to chain conversion on a Dyna. Thats why I was wondering if a Dyna sized axle could be used with a swing arm.
Yes Im sure I will get roasted here. And told go do a search. But any help would be appreciated.

In general, I prefer to think in terms of dimensions rather than models. So when you say, for example, "spacer for a Dyna", I think you'd be better off saying "5/16 thick spacer" (or whatever the required dimension would be). Same thing with axle size. I don't know what came on a 2011 Dyna. Was it 3/4" dia, or something else?
Sounds to me like you just need to get this mocked up, laser (or string) line everything to see where it lands, then sort out your axle and sprocket spacers from there.
JMHO.

Now, as far as sprockets go...
Specialty Sprockets might be an option. Or
Vortex Sprockets. (I used Vortex on my "big HP" bike. They put up with my185+ HP...)
Since you're only running a S&S 124, you should be around 135-145 on the ground. That's easy.
Bel-Ray makes a good chain wax, fyi.

Zippers has a very good selection of trans sprockets.. I suggest you get together what you want and then measure for an Offset front sprocket... When it goes custom there is no standard....
