I do have a ported head by xpr, xpr cam and ti ex valves, with xpr vortex ecu in my crf450r 2017 engine…really easy to use and plenty of power everywhere….pulls much more stronger than my stock crf450r 2022……With my 2022 I will start with a xpr vortex ecu…..Chad makes really friendly power with those engines….is you have the budget go ahead, you will enjoy!!
