Hi, I have a new to me 06 153 M7. It has an aftermarket can (don’t know the brand but it’s loud - debating ditching it). It runs pretty strong til 6500 +/- RPM and then it’s like it hits a rev limiter and falls on its face. It appears that maybe the belt is riding a bit low in the secondary. Most of my riding has been playing in a field and riding on ungroomed trails. Unfortunately, I don’t know the whole store on the sled but it’s most recently from MN and that’s my area as well. My mechanical ability is about a sophomore level but I’m will to try. Any guidance would be greatly appreciated. Thanks!
