You will be pleased with it.

Break in

Do not soften the clutch too much, if at all, motor must not lug.

With the motor preheated to 90 deg.C before starting.

Set just rich enough to not shift gear and run it as hard as you can.
Keep the temp above 80 C.

Keep running without a break and fuel every 3 minutes or so.
The motor will richen up as it settles in, just retune when it does
to just before gear shift point again and run hard.

Will prob take about 2 litres of fuel to get to race tune.

Should have a shiny band that is only between the 2 oil grooves on the piston when done.
