One piece Vs stock starter jackshaft?

[Twincam8888]

2004 Mastiff with the usual S&S 107" closed primary and a 9 tooth/66 tooth starter gears. I had a lot of "grinding noise" start recently and the stock style jackshaft assembly is not receding and seems to be binding, It seems to sometimes bind even sliding it manually with the starter removed. Have any of you used the one piece jackshafts? I'm going to put something new in there and wondered about trying the one piece jackshafts. Thanks in advance for your thoughts.

Someone should answer, but my thought is; why not pull it apart and see who is hanging up? Only thing I worry about is what [chemical] to use so the wire epoxy does not melt and touch the windings after cleaning. The old grease may have caused the binding on the return. Being slightly bent on the sticking side is another issue to address. Here, I'm thinking of caked grease.

Yes, I'll get the clutch off tomorrow so I can have a better look at all the jackshaft parts.

I had to run the one piece on my 03, with the open primary, to keep it from hanging up. I don't know what it will do with the closed primary
