800/1000cc Break In Procedure

[A126]

I bought a brand new 09 M1 SP this year, and the dealer I bought it from went through the whole break in procedure where the engine is running (while on a stand) and revving it up not exceeding 6000 rpm until it overheats and then repeating that step again. Then my buddy went and bought a brand new 09 M8 SP from a different dealer, and they never went through this procedure on his sled and never even mentioned it to him.

Is this something that only some dealers practice or is this something all dealers should be doing?

And is there any concerns that my buddy should have if he rides the sled without doing this procedure?

Thanks

You have a better dealer or they know him better. I always run them on a stand a couple of times and then let them cool all the way down. Then easy rides varying the throttle with short hard runs. After first tank of gas, fill it, and then ride it like you stole it.

The dealer is supposed to do that to the 800 also. When mey friend and I got our m8 last year the dealer didn't do that. Of course we didn't hear about the break in procedure until we had ran a few tanks of gas through them. Our sleds have been fine just breaking them in the old way with exttra oil in the gas. I think that the 1000 were more critical for the new break in procedure.

I bought a new M8 HCR and my dealer didn't know anything about that procedure either. I only found out through snowest. At most my sled has been started to get aboard my truck and then to my garage. Not sure what I should do to break it in.

The key on breaking any engine is not overheating the rings and taking the spring out of them. When a engine is new the cylinder has hone scratches and rings with uneven edges. As the engine breaks in the rings and the cylinder loose there rough edges and begin to match creating a awesome seal. Excessive load on break in can cause the rings to overheat allowing for vertical scratches to the cylinder. That why running unloaded on a stand varying the rpms is good because the engine in under a low load. After that you should not hold the engine at max rpms until you have a 100 miles or so. I was taught this at technical school the instructor made us look at a new piston ring under a microscope i was surprised how uneven the surface is on a new ring.

I have never ran any of mine on the stand. I pre-mix the first tank, and run it (trail only) varying the throttle constantly. No sustained throttle, and only short bursts to full. I do this for 100 miles, then run the hell out of it
