Bought a used 2010 summit x. Can not get more than 7650 rpm ( under load or with track suspended) hits 7600 then starts a very faint miss. ( not clutching ) new gas, plugs, and cleaned rave valves, and checked compresion (147 & 148 after market heads, not sure what make. Need help! Could it be faulty rev limiter or? Thanks
