copemech Posted October 30, 2018 Report Share Posted October 30, 2018 I do not think so, as there are a lot of subtle changes. Go ahead and try so you can tell us! Quote Link to comment Share on other sites More sharing options...
pauls320 Posted October 30, 2018 Report Share Posted October 30, 2018 Pretty sure the position of the motor mounting bolts and swing arm pivot points are the same but the head support bracket may need to be customized as 125 and 270 barrels may be different height. Other than that , as cope mentioned there my be other issues...coolant hose routing , etc, 2011 was new style h20 pump if remember correctly...post some pics etc of your build for us Quote Link to comment Share on other sites More sharing options...
