Engine break in methods after rebuild. Opinions on this method.

[jimmy-turbo]

ive used this technique of thrashing it in on every bike engine ive built  and after picking up my new engine two days ago (t2 vert )have been applying bits of it to the running in procedure (mainly due to me not knowing if the combustion gasses pushed the apex seals against the rotor housing like the piston rings get). EVERY bike engine ive stripped after a rebuild has had the piston rings bed in faster and look a lot cleaner. Blow by on the two strokes was reduced near the exhaust ports considerably.

i spent the first couple of hundred miles running it in under load but about two thirds revs and after 500m gonna change the oil and thrash it :Giggle
