Interested to know when you would class an engine as being run. My new 380 VRX has done 3500km, and although I have put my foot down, I have kept the rev's below 3500rpm. Now want to see how it goes getting up to 6000rpm.

1K or 2 should be enuf for running in, now u should be able to stretch its legs:think:

apparently running in you should actually get it up to 6000 or sumthin. i think asylum and some others mentioned it somewhere...

Running your engine in for the first 200 - 500kms will determine how long and how much power it will produce.

Running it lazily (without revving it out to almost redline) will sometimes guarantee a longer life but less kw's.

These days the first few hundred k's should be driven aggresively, almost to redline. This enables you to get a nice tight seal for your pistons.

You should not be using the top end gears as this labours the engine. Always change your gears to keep the engine revving differently.

All the above is for the first 200ish km's..

me and a mate bought identicle bikes. I ran mine in carefully, did everything right and he flogged the piss out of his from day 1. His makes 10kw more on the same dyno. If you're not going to keep it for 10yrs and 300 000kms why do you care. Go on give it a flogging and do you're self a favour.

a mate of mine recently bought a new bike and was advised (when cruising/travelling a distance) to rather than just let it hover, just every now and then change down a gear, then change up every now and then ... really use the entire rev range

Im not too sure if this application can be used for cars, but i cant see why not
