How many miles and what sort of revs should run at on a rebored and rebuilt crank 4L0 motor.
Cheers.

Heat cycle it at least 6 times Run it 'til it's warm .. let it cool down to ambient temp.. then repeat. Before riding it
Pistons need heat cycling to relieve mfg stresses .
Or you just wail on it... then wonder why it makes odd noises or why it's not as quick as you'd hoped :-)

Some load on the engine is important - limit the revs but not the throttle so much. Rings need some pressure obove them to get them bedded in
