Only 8,000 miles. And 4,000 miles since service last fall. I know, I don't ride it enough. LOL Anyway, we are attending the ICBTC in Nashville in three weeks. Decided to get her serviced with fresh oil and filter. And to have the trike fully serviced. Got a call yesterday to inform me to pull the drive shaft was a three hour job. At $80/hr., I hesitated, but gave them the go ahead. Got another call this afternoon, drive shaft was worn down and needed to be replaced. CSC ok'd the repair, everything was warrantied. Service writer said it is all new parts that are different than mine. Some changes were made. He didn't elaborate. I'll know more when I see the bill I guess. 8,000 miles and I don't abuse my baby. Upset? Yes. But glad they found it before it failed on the road. Tom
