Thanks for the welcome Gents.
The engine hasn't even clocked up an hour yet, so I've been keeping the trips short and rev's not too high. She runs OK once warmed up. Seems to miss time at high revs but haven't had it up that high long enough to know for sure.
I'll post up some pics as soon as I can find the blasted digi cam! ...especially my creative lower frame mounting point... stoopid extra large oval frame caused me some grief!
