OK,I'm sure some of you guys will know this but it may help some also. I had the dreaded ratcheting noise at the start also, kept checking track an chain tension every day,then noticed (at approx 150 miles) to get correct chain tension I had to also back off plastic washer behind jam nut, found out bolt could screw in 1/2-3/4 turn farther (finger tight), thinking back I have not heard the ratchet noise after that, could it have been the chain all along? I'm gonna loosen the track off to see how loose I can run it now, may just solve some problems. I now have 300 miles, what do you guys know/think about this.
