I was Driving Xray NT1,
Axial Spec 1 .12 engine.
Team Orion 6 turbo Plug
0.32mm head shim ( used 4 x0.08 Axial Head shim)
Fuel Tornado 25%
Pipe HEC 6mm

I set the bottom needle on the rich side compare to last year after I have the Top needle set.

Temp at plug been 95 to 98C

Clutch, used all standard parts and setup from NT1 except the clutch spring was the Serpent long hard spring.

After I inspected the engine last night, the compression is just like before the race . No rebuild for at least 1 more gallon on the conrod.
