Started having a bog issue today, it was intermittent and didn't happen too often, changed plugs and I thought that helped. But then the last couple times I pinned it wide open the primary clutch stuck engaged. Got it free, headed down the mountain and tore it apart to find that the one front roller has a nasty flat spot in it and even wore the weight a bit so it has a wavy surface now. Anyone else have this issue? Of course nothing is open after 5 in Revy so I'm going to have to wait until the morning to try to find a new roller and weight.
