[QUOTE="yamafitter, post: 949232, member: 15141"] I have never heard of anyone burning pistons or valves from high speed runs with the FJR so I doubt that the bikes are running lean at WOT. I am thinking one would need a flowbench and a spare head to figure out if any performance gains can be made by altering the exhaust and intake ports. Too expensive IMHO. UselessPickles has done the most work of anyone I know of on the forum with tweaking mapping and dnyo runs so I would shoot him a PM with your question. [/QUOTE]
