Cheers guys, I think it's time to wrap a wet towel round my own head and jist send the bikes head to Norman White and get an insert made. A would like to go to the NOC red bull ring rally on this bike and there's no point in chancing it on a big run. I'll speak to him today and see if he can do it. The fact that it's came out twice does not fill me with confidence.
As for your comment Steve, down for a pound.....yer right!
Chaztuna, spark eroding the timesert , tried to get info from wurth the timesert suppliers ,they were poor and uninterested in the problem. I still would like to find a course for the missing bits on the 'cert as they are almost identical!
