Yes all clay, it is the double single that was easy with the 4.1 is now three singles and I am now loosing time, I can hear the slipper gripping and not buzzing up. It is no where near lifting the front wheels. Diff is tight , I don't normally ask for help but I am a bit lost with this one. I thought my gearing might be the problem but I will re check my slipper again, thanks for the help
