Well isnt that cute - now only if he had a clue

Think about this for 1 min.

Dismiss what the engineers have come up with for a "break in procedure".

Instead follow what your friend the motorcycle technician at yamaha said. Besides he knows more than the engineers that designed the engines...and the FEA programs, NVH tests...and saw the results of the stringent dyno and track testing that was done on the motors

And if it works on one mortor it must be the same for all of them, right!

 

I see some good rationale on both sides.

I've had 25+ bikes but only 3 were new. My first two were VERY gently broken in and the third, my first 98 SuperHawk, was harder but with temperature cycling. They all ran fine but I never put more than 16k on 'em so it didn't really matter! Unless you're a lifer like caffineracer with over 100k on his 98, then this is all somewhat acadmeic for a lot of riders.

Way back when as a high school senior, I worked as a mechanic's helper at a diesel shop. The chief mechanic regularly broke in detroit diesel V-12's which were both turbo AND supercharged with full throttle runs. These 2-stroke diesels were also mechanically fuel injected with 4valve heads. Pretty damn hi-tech for a diesel. Pretty damn heavy too. I could barely lift one end of a crank. After a cool down and valve clearance check, they were sent out to run 24/7 on drilling rigs.

 

Interesting. When I was a kid out of high school I got a job on an oil rig running air compressors powered by those V12 diesel engines you are describing. Those were big babies and you had to start them using a 5 hp. Briggs & Stratton.

 

So again...rationale is "the engineers said" but in reality when a person regularly assembles and races motors with redlines over 16K RPM, the motors broken in hard, 100% of them turn better figures, and most all of them live 30K mile track lives before a rebuild. Most of our street driven bikes don't even have 30K on them, let alone hard driven track bikes.

As I've said before...it's all for the sake of lawsuits.

But sure, the guy professionally building Yamaha race motors, his break-in procedure will be different than the guy whose building Honda motors...they're worlds different. Real world results bear no weight against that of what "an engineer says" in a home manual.

 

Basically, this is all just banter isn't it? There's this way, and there's that way (I think someone even talked about peeing on their bike after putting peanut butter on it?). We aren't talking about a high compression motor, or problems with blow-by in a racing pressure-packed cylinder. These motors are factory finished well enough that ring damage should be the least of your worries.

I guarantee you that Honda and Yamaha engineers (Maybe even Kawasaki, but you never know) know PLENTY about clearances, and that these motors should be ready to go race after mile 1. With that being said, the break-in procedure is just a matter of opinion.

Have you guys ever seen a Superhawk at the track smoking from ring deterioration? Prove to me it's a serious threat to my bike's health and I'll be all ears!

If you are going to abuse your motor, or at least run it at its limit right from the get-go, have at it. Very few of us get to enjoy our Hawks for 100k miles anyway, and your rings will seat just fine whichever method you use. I'm no engineer (wait a second...) but I say we just agree to disagree.

What cracked out Moron talked about pissing on their bike after putting peanut butter in the tank? I guess we see all types of freakin freaks on here....They can't all be as sane as us Loco....I mean I am no Mental Patient (oh wait).....

 

I know it's not even really a big deal...most people probably wouldn't even notice the 1-5 HP difference. And the results are mainly for racing purposes where you want to squeeze out the most performance possible. Trust me, anybody that has a track bike knows that tearing down a motor isn't something you want to do on a regular basis, so if it were utterly damaging to break-in the motor hard, I don't think most would....

My point is just that, if you're going to have a performance based platform, wouldn't you want to be able to squeeze the most out of it? I'm not gonna bag on you, or like you any less just because you broke in your motor gently....I'm just wondering why you wouldn't want to get the best possible figures out of it?

 

If I was in that situation where my SH just wasn't up to the challenge, I know exactly what I would do. I would sell it and buy an RC51.

Thanks for not "bagging on me" because I didn't redline my bike after getting it, I got mine with 12k on it, and it runs like a champ.

One can always figure out a way to add a few fractions of HP here and there (I doubt highly that's its in the 1-5 Range but I'm no ... ). It's just a matter of preference for me, and I'd say that most of the casual riders here would agree.

I'm not trying to start **** with you or anyone on this issue, because there's just no reason to get worked up over something so inconsequential in a bike's life. It's like circumcision, everyone's got an opinion.

 

We shouldn't operate on the assumption that ******* a new motor produces horsepower.

 

Although...it doesn't "produce" HP, it sure as hell doesn't subtract any...like I said, his real world results proved the hard broke-in motors threw better numbers. Everybody knows you can build two motors with the same exact parts and tolerances and stick them on dynos right after another, and one produce more power than the other. "Coincidently" all the hard broken in motors had higher figures...compression and leakdown tests all showed favor towards the hard run ones...coincidently of course... :wink:

Otherwise, I could care less how one person breaks in the motor compared to another, definitly not starting ****...just stating my opinion and brining my info to the table is all.

 

At least you're not peeing in peanut butter like some of the other VTR riders I ride with.

 

Dude, get it right, he said, putting peanut butter in the tank, and pissing on the bike.....G's ......Seen any suburbans on the track lately?
