iansoutham Posted May 18, 2016 Share Posted May 18, 2016 All you need is the cap and rotor arm from a non-injection version with the Bosch cap. Had it on all my old xr3i models. The power drops off around 5000rpm if you leave it in. Doesn't work well if you have a cam that is working until over 6000 rpm having a restrictor like that.

My system is bosch. I have loads of new caps which will work with the arm. Just making sure I'm safe using it. Quote Link to comment Share on other sites More sharing options...
