I have my clutch hub off and drilled out the rivots on the flywheel ringear to install the Rivera 10-84Tooth ringear/starter pinion that I should have Monday. I noticed that I have 6 splines on the outside edge of the clutch hub (female splines) that have a about 3/16" of the splines missing. The rest of the splines look/feel good when scraping with a small screwdriver. The trans input shaft splines are good. This clutch hub where the splines are appear to be a cast part?
Should I buy a new hub with the ringear and bearing (I believe over $200), the 37806-03 hub that contains a new clutch ($379), or put it back together and don't worry about it?

I believe for the way I ride it wil be ok.. The bike just turned 25,000 miles. If none of the dealers have one in stock, I would have to take it apart again after York.
I believe I read where a fellow had his strip out all together. Maybe the clutch hubs all look this way after a while. Any help would be appreciated.
