I understood that the 1125R came from the factory with Syn3 in the oil sump or am I wrong? |

IIRC that was a rumor about the SYN3 from the factory. 18 months ago there was a thread on this subject and a reliable source stated that Dino oil was in all 1125 engines.
After my 6,000 mile oil change, I went to the SYN3.
FWIW, I changed my oil at 50 miles, 300, 600 and 2500. I just feel that clean oil and filters in the "formative miles" is the cheapest insurance for a healthy and long lived engine.

Yep, I agree on frequent oil changes during the first couple of thousand miles and have just dumped the oil and filter at 100 miles, replacing this with an Buell filter and Syn3 - thinking that Syn3 was the same as the original oil I was replacing - hope I have done the right thing here. |

Hmm, engine braking vs engine break. Are they different? The SAE paper say brake, the link says break. I interpret engine braking to mean engine decel.

Boltrider, the SAE paper spells it "break-in" when talking about the first hours of engine operation. Where it uses "brake" it is when talking about brake mean effective pressure. To put it simply, that is the pressure produced inside the cylinder as measured using a dynamometer. |

Dentguy - thanks for the link I feel at lot better after having read the doc - cheers and safe riding |

I looked up Break-in for my 06 cbr1000 and it said for the first 300 miles no full throttle and that was about it. The Buell has a whole page of rules for Break-in. Both bikes were ran very easy during Break-in and don't seem to use oil and run fine. The cbr has 20,000 miles now and the Buell has 3,500. |

Don't slow down now, actually speed it up and you will be surprised at how good they run after they are completely broken in. I felt a noticeable improvement after 5k miles.

For those of you who believe the "by the book" method is the best way to run in an engine (the phrase I prefer), consider this.
Each Buell rolled off the assembly line is put on a dyno and run WIDE OPEN through all the gears. I've seen it in person. I saw them take bike after bike RIGHT off the line and run the ever lovin' pi$$ out of it.
Another thing to consider is the legal aspect. If the factory endorsed the Motoman procedure, and someone crashed their bike doing an aggressive run in, the lawyers would have a field day.
Motoman doesn't endorse abusing the bike, or riding around at redline for miles on end. It's a varied approach. Use the entire rev range, and allow the engine to compression brake back down.
It all makes sense to me, however, puttering around lugging a new engine doesn't make any sense to me. |

A conversation I had with the service manager when I bought my BMW:
me: "How do I break it in?"
SM: "What do you mean? Just ride it"
me: "But aren't there specific cautions?"
SM: "Yeah. Don't lug it and don't redline it for a couple of hundred miles."
me: "ok"
End of that conversation |

break in a engine on a dyno didnt come from that guy. and u will do damage to ur rings called micro welding if u flog ur motor(this doesnt mean proper breakin on a dyno). now u got a engine 25 percent down on power. its been widly documented by engine builders.
excessive engine heat is a killer to new engines. |

jmr1283,
I don't understand your post. An air cooled engine regularly runs above 225 degrees. ref: http://www.type2.com/dakhlia/overheating.html. As long as long as you don't let the motor get that hot (read "water cooled"), then you probably don't have a problem. btw, I broke mine in according to motoman, changing the oil to Castrol GTX at 100 miles. while I kept it below 6500 rpm, I usually tried to pin the throttle as much as possible and tried to keep a heavy (>200#) passenger on the bike as often as I could. Changed the oil at 2k miles to mobil1 for twins. I'll bet you a dollar my bike is a strong as any. Motoman rules! |

okay do u know what the engine is running for temp on the 1125... most air cooled dont put out this power so lets put it into a percentage of work load. our water cooled would produce much less being air cooled, becuase u cant expect it to have such high power with out problems(or longevity). so since it is allowed to push more power u think that it does run the same temp. hah i laugh! it doesnt run the same temp.

I found this discussion on the Lawrence Livermore Research Laboratory website:https://www.llnl.gov/str/Westbrook.html
"One major project of the (Lawrence Livermore) research groups modeled flame quenching at engine walls. In the cylinder of an automobile engine, a flame ignited by a spark propagates through an air-fuel mixture and toward the cylinder walls and piston. Modeling results seemed to support that traditional view ... that fuel (is) trapped in the cold boundary layer at the wall. Later research confirmed that unreacted fuel in the piston ring crevices is actually the primary source of unburned hydrocarbon emissions." |

this is a pic of the break in for mine. the odometer rolled over to mile #2 during this wheelie...
isnt that how you are supposed to do it? |

nicely done rice. I had similiar moments with similiar milage during the breakin. |
