On a xm with 3” you need 7 tooth drivers. 3” pitch. Not sure if tracks went back to 2.86. But most the old ones 3” pitch. Its very tight with 7 tooth also.This was before factory 3” of course. The 3” sleds have longer chaincase.
My findings as well . A lot of cussing and soap and water even with the 7 tooth drivers . Lol
