Hi all, I've got a 2010 SM with MRD/SSW, jetting and 3x3, which has developed a flat spot in the middle-rev range when accelerating. Seemed to just 'happen' mid ride a few weeks back. Until then the bike had been awesome. The only thing that I can think of is that the cam chain has jumped a tooth and my timing is now out. The ACCT hasn't been doing it's job properly, and the chain's been making plenty of noise, perhaps it was very loose. I've got an MCCT going on this week, and will ask for the timing to be checked while in the shop. Anyone got any ideas? I'm not familiar enough with the noise of pinging, and I can't hear much thanks to the pipe, but I could swear that there is a minor knocking audible from somewhere. Still starts and stops as easy as ever.
