I would try that before I would ever buy another SE compensator. I have had two, and hated them both. I am still running the stock comp. on my 124 with no problem. Waiting to see if Hoban's comp. pans out. I know a few people that are running a solid sprocket, and they have no complaints. I have a welded crank and an IDS rear pulley, so I think it would be safe. Thanks for the link. I couldn't remember who made that.
