The Ryca guys are concerned about my intent to convert to chain drive. In designing the kit, the clearances between the rearset brackets and the belt were carefully worked out in conjunction with the longer shocks. The chain sprockets are smaller diameter than the pulleys, making the space inside the chain smaller. The chain might rub somewhere.
But I hate the look of belt drive, so I'm going to make chain drive work, one way or another. To that end, I got one of these. It's supposed to be a chain tensioner for Harley choppers, but I figure it can be used to hold the chain away from the rearset bracket. I'll know where to mount it once I get the rough assembly done with the rearset bracket, longer shocks and chain drive. It could be welded to either the swingarm or rearset bracket. Some cutting might be necessary.
