Haven,t chopped it yet, went down to a 125 main and put the filter back in again. A t least its rideable now though still not there yet. Will drill the air box lid and see how that goes. Have a set of 122.5 mains but dont know about tryin them. Havent chopped it yet cos it of how poor it was running so now its gettin there, soon. By the way already replaced the float valves.
