Since upgrading my 6401 to 7901 I wanted to try out an 8-pin sprocket to take advantage of some of that extra power. I bought the appropriate Oregon 22273 rim sprocket to give it a try. Everything fits just fine except that the chain now hits the rubber chip guide/deflector. Looking at the IPL's I don't see a special chip deflector for 8-pin sprockets. And if I hog out the existing deflector to fit I would have to remove nearly all of the rubber at critical points, thus defeating the purpose of the chip guide. Any of you fellas run into this problem before and solved it?
