Average RPM 7500. Lowest used RPM, 4500.
Total hours on motor are under 60. Just hit 2100 miles.
The iron and aluminium content concerns me.
Checked valves yesterday and they were all perfectly at the loose end of spec. Yamaha specs checking them at 600 miles. I checked them at 2k. Will check them again at 10k.
Thoughts on results?
