2021 155 axys 850 with boondocks agility kit. Starts and sounds fine on idle. WOT only gets to about 6300 rpm and stays there. I have swapped plugs, checked crack pressure on the boondocks, power valves seem to slide in and out smoothly, primary clutch disassembled and inspected, no lights on the dash, not sure what to try next. Is the rpm a limp mode even if there is no light on the dash? Any help appreciated. Thanks.
