Don't worry... you can continue the factory break in procedure by any
route you choose... the key is high revs... you see at the factory
they have already run the engine at high rpms to help seat the rings...
they are not thrashing your engine... you're doing what your engine
requires... The purpose of high rpms is initial seating of the piston
rings to the cylinder walls. The run is conducted at full power
because that is where greatest B.M.E.P. (Brake Mean Effective
Pressure) occurs and a high B.M.E.P. is necessary for good piston ring
break-in.
How do you know if break is done??? take a compression test... if your
engine shows factory compression then break in is complete... if your
engine shows less than factory compression then more break in is
require...
I lived in Japan for 3 years and I made the pilgrimage to every Honda
factory on the Island... They would build a bike in 12 minutes then
run it to red line on the rollers like you see in my pic... it's not bike
abuse but its needed to seat the rings in accordence with the engineers and designers...
12 minutes to red line... Mamamatsu Factory...
