Thanks for your help and advice, running in was a breeze and would have been totally wrong with the tuning,
No worries. Glad it's all working for you

The new 2072 rocks on the GX and the Pro series motors. I think someone else mentioned this a couple of pages back - we had a problem with a couplle of pipes from one batch with the springs pulling through the holes, which seemed to be drilled a little close to the edge of the flange. Also the springs are very short and a tight fit. If you think the holes are a little close to the edge, just use a slightly longer spring.
We only found this on two pipes out of a maybe 20. Also, if you have one of the new low-profile style bodies you will need to apply some aluminum tape to the underside where the pipe sits. Because of the larger volume chamber on the 2072 it will contact on the low profile bodies on most models. But a small bubble in the paint work is worth it for the performance gain.
