alright that sounds good then... im pretty sure i fugured out where its coming from.. the tailshaft is on too big a lean and the uni joints are abit lose. its in the shop now going for blueplate. needs a couple of things. 3" blocks need to be replaced with 2".. few wires need tidying. a few oil leaks and small things. and needs a cover over the surge tank in the tray.. then it should all be legal and ready for a thrashing haha... thanks for your help boys
