While waiting for a call back from Tubeworks tech thought I would pick the brains of the 'in the know' on this site. Second ride with IRP and clutch mod when clutch became very sluggish reengaging afer downshift coming into down hill corner. Applying power to soon would result in slipping clutch and high RPM's causing a very hard engagement. If I would wait for the green slip indicator light to go out all was good. Also if i would downshift in the corner AFTER applying power it worked properly. Start off's as well as all up shifts work perfectly. Thanks for any ideas!
