I just got the WERKS GT engine after wanting one for some time. Both my Mernen Mugen JX21 and my REDS engine's, after faithful service have both passed away. :-(
So now...... are we still putting an extra 0.1mm shim on the head when running the WERKS engine's? (25 & 30% nitro)
I had heard some time ago that the engine run's so much better that way?
Regard's
