I got a new cdi.havent put i in.I replaced the lines,redid the plug wires adjust the low needles to factory.Then ran it..still a bog...Seems the cylinders feel hot to the touch..sometimes to hot to keep my hand on it...I took out the thermostat and tryed it..The ran slight warm.If the guys that redid my engine put the carbs back on in the wrong order,would that make this bog.I notice in the man, the jetting is different mag end ,cen,and pto .I havnt check that..
