To begin with, I research prior to purchasing most anything. It was my understanding that a 325 chain would cut faster and with less vibration than a 375 chain. I just purchased a 28", 325 Cannon Superbar on ebay for my stock MS460 but failed to check the options for a rim sprocket. After the fact, I discovered I failed in my research and the only rim sprocket option is a 9 tooth.
The Stihl sprocket I purchased is the same outside diameter as as their 375 8 tooth, but I am concerned about a reduction in performance. I am in the process of dual porting the muffler and I will primarily be cutting oak. The ebay seller gave me the option to return the 325 bar and purchase the same bar in a 375, but said the 325 9 pin sprocket will work very well with this 28" bar. The 375 bar would give me the option to run either a 7 or 8 tooth rim sprocket. I think I should take him up on the offer but wanted to get guidance from others. Thank you for your help!
