So Croft was a mixed meeting for us as a team, the X7 giving up wasn't part of the plan, Keiths RD making lots of noise by the end of the weekend was a concern meanwhile the Maxton ran really well for me. Having stripped the X7 motor, it is clear to see the failure mechanism which was poor quality pistons/piston manufacturing. The ring pegs have either broken or pushed in, allowing the rings to spin and fail in the ports.
The barrels have been sent back for investigation along with the pistons, and also will need reboring. While that is being done we are preparing a spare top end for the bike that we didn't have available at Croft. We have the option of a lower spec tune to drop on as a back-up or even a set of totally standard barrels that will do for getting Dad out there in an emergency. The X7 bottom end has since been stripped, washed out and fortunately is fine so will be going back together with a fresh top end for Cadwell Park in June.

The Maxton top end will be taken off for a check over and I have some small changes to make to the rear suspension which I think will help the handling further. Keith has a job on to strip his motor this coming weekend to find out what the noise is and we will need to work quick to get that back together if it needs particular attention.
Nigel had left Croft with a small to-do list which he (through excitement after the weekend) had done and dusted by the tuesday night - so the K4 is sitting ready to go for Cadwell with some changes made for bit more top speed and also new longer rear shocks.
All I'm going to say is that its lucky we love 2-Strokes....!!
