Yes, we ran split sprockets for almost 10 years. The major issue we had was ensuring alignment and spacing at the split. We tried precision drilled holes, fixtured locating, but when you are working with a 26 tooth sprocket with a 1/16 saw split there were still a few issues now and then. Fastest we went on splits was 221 with the one liter. We redesigned the center carrier and the removable axles and changed to a regular sprocket. Yes it is more work to change but we usually only do that when we change engines. If you are going to WOS, drop by and look at it.
See ya on the salt
