     Whodom |
I finally picked up my new Ulysses Wednesday night. Sat down to read the owner's manual in detail last night (yes, I'm an engineer). As I read through the break-in RPM limit recommendations, I thought "I know this isn't as restrictive as the break-in limits I've seen mentioned on Badweb." I just went to Buell.com; the 06 Ulysses manual is accessible on-line there. Basically it says keep the engine below 2500 RPM at all times during the first 50 miles and don't lug it. From 50 miles to 500 miles, don't exceed 3000 RPM or 55 MPH, and try to vary the RPM. My 07 manual says to keep the engine below 4000 RPM during the first 50 miles and below 5000 RPM from 50 miles to 500. After 500 miles, rev to your heart's content. Wow, that's a pretty big difference. Seems like the 07 recommendations are MUCH more reasonable and easily maintained while still riding the bike pretty hard to help the rings seat. Anybody else notice the change? | ||

Motoman pretty much except for the oil change at 50 miles recommended by the motoman. | ||

That's not "motoman" at all, EG, although it is a huge improvement over the old procedure. Keeping that engine below 2500 rpm is almost impossible. | ||

Actually the motoman method doesn't say rev the living poop out of it at all. It does say use lots of throttle. Now with this new rpm limit it is doable just like motoman says. I guess Buell noticed a lot of oil using Ulys. I broke mine in hard and I did a 5000 mile trip this summer and guess what. I didn't add a bit of oil the whole trip and that was 2 up also. | ||

Dang - I feel like I wasted a week of my life. *sigh* | ||

That's what I was thinking. I haven't had many new engines to break in, but I always remember what the owner's manual on the 1971 Plymouth Satellite my Dad had said: "Brief periods of wide-open-throttle acceleration, within the limits of the law, will contribute to a good break-in." Oh yea, the "limits of the law" part is optional.  | ||

Thats about how I broke in my '06. The '06 method was way to easy on the motor in my opinion. David | ||

The "motoman" method is a pretty specific procedure involving intervals of hard acceleration and deceleration, up to full throttle. I don't believe the new break-in specs mention any such thing. All they did was raise the maximum revs. For the "motoman" method to work (if you believe the hype), the hard accel and decel is crucial. So while the new reccomendation may more easily facilitate the "motoman" method, it is in no way an adoption of the method. And unless I've missed something, there's not been any conclusive evidence linking break-in method and oil usage. | ||

Way to go Buell! That has been an issue that has bothered me ever since purchasing my first Buell back in 1998. How do you NOT lug a Buell and also keep it below 2500 rpm? It is tough to do. Thanks for advising us of the new wear-in procedure Hugh! This most likely should be retroactive for any prior rear models too, no? | ||

Just a question: What does it hurt to do a Motoman type break in? | ||

What does it hurt to do a Motoman type break in? The argument against Motoman is that it seems to go against what most manufacturers recommend for breaking in their engines. You know "The people that designed these engines set these recommendations; who is this Motoman dude anyway?" A Motoman break-in would clearly violate the recommendations of the 2006 Buell owner's manual, so technically you could void your warranty if there was some way for the dealer to prove you regularly exceeded the recommended RPM limits. I think it's possible to more-or-less do the Motoman method within the limits of the 07 recommended RPM limits. I've seen a significant number of people claim good results from using this method to break their engines in (good power, low or no oil consumption, etc.), and I haven't yet seen one post say that using Motoman hosed up their engine. | ||

#3 Drive slowly and avoid fast starts at wide open throttle until the engine has warmed up. Warmed up! Loading the engine(not lugging) to cause the rings to seat by the combustion pressure on the back side of the rings forcing them into the cylinder walls. When I used to build racing engines(a very long time ago) ring drag was measured, as too much was considered not a good thing in a high performance engine. The engine would go from the build room, to the dyno, and it was loaded (big time) after it was up to operating temperature. Once everything is up to operating temperature, not a whole lot goes on, the bearings don't break in, the cam doesn't break in(though the critical time for a cam is cranking and not starting) there is nothing left but the rings. | ||

Is there any difference between the 2006 and 2007 engine? | ||

Heads have different part numbers, but no one is sure why yet I believe. | ||

Oil pump is different with increased scavenging capacity. | ||
