Keep up the good work Ray.

I really didn't expect much after my OS being resized but i have to say that i was so impressed by the performance of the engine and would like to know how many times i can resize it?
I broke it in using 6-10 tanks of fuel, had a 3 day race with it and still get a noticeable pinch on top when i remove the plug and turn it...this is a sign of a good break in and excellent fitting.
Thanks again.

Will be sending my Tecnopower in for resizing soon.
