Hello
It happened very quickly , about 7500 -8000 rpm in fourth going up horsepower hill. Sudden loud noise and immediate loss of power .
I think that a valve or valves failed, causing the piston to disintegrate and get caught up in the crank and damage the engine case.
The bike had less than. 10,000 miles and was set up on a dyno with a power commander 3. Fueling was perfect. I have performed meticulous maintenance
Schedules.
A new engine will be acquired and fitted during the autumn/winter.
Will be back next year racing.
All the best
Gus
