How Do Rings Bed In?

[imdying]

But...but...it ain't got the "doof, doof"...I am (and probably always will be) a Vtwin girl.

It is a v twin... just not a ghey diesel one

And a SV1K boring???? wash your mouth with soap, young man

Compared to an RGV, it is... sorry

Ok then, if you say so...Mind you, with my riding proficiency, anything going faster than 130 k/hr is exciting

I am so easy to please.......when it comes to bikes of course!

So I guess someone who would hit the rev limiter on a brand new bike would not be doing it any favours then?
How much damage could it actually do?

PS: not that I would do it, but I saw this woman do it to a brand new CBR600 at the Cold Kiwi and hated her for it! Cos I want her bike, maybe...

Materials and manufacturing tolerances have improved a lot, what works for a cast iron bore doesn't nescessarily work for a modern hard chrome bore with a mirror-like finish from the factory.

If you look long enough you'll get a full set of conflicting advice from a range of genuine experts. I tend towards this guy's thinking. Mostly. Unless I don't agree with that bit...

Hmmm, ok thanks for that...

I shall get the in-house engineer to have a read up and make my mind up for me on this!

[vifferman]

Thanks Vifferman, I know I can always count on you for knowledge...

Oh - you were probably misled by my removal of the "and that's what I think.. or something.. or not... dunno really..." signature line.

I just make stuff up.

But...but...it ain't got the "doof, doof"...I am (and probably always will be) a Vtwin girl.

Yeah, y'get that.
It started for me when I first saw/heard the original Ducati 750SS, then was really rammed home when I first heard a 916 with Termignonis, and having owned a v-twin, I now know what it's all about.
Must get me another one, one time...

A V4 is a case of "close, but no cigar..."

Yes... there is that.
I guess the rings still need to bed in a bit, and the engine parts go through a few heat cycles. But a pressed-in nicasil bore isn't going to change appreciably in the first 50,000 km or so...

Nuh uh, I don't buy it...but nice try El Humblo!

Exactly...there is just a magic about the sound of it, the way the engine braking power assists, the rumbling of that engine under the rider, the way it just howls out of corners...

'scuse me, I think I need a moment here...

You get a similar flat drone from the V4 - I like employing "excessive or unnecessary acceleration" just so I can decelerate excessively to hear that noise.
But the howl at >8000 rpm when the Satantune's got the spud out lifts the hairs on the back of your neck in a way a v-twin doesn't.

[Ocean1]

...the way the engine braking power assists...

Smatter of fact I could do with a bunch less assistance there, tad too exciting occasionally.

Suppose I could refrain from stomping it down two gears way too late also...

What he says seems to make a lot of sense... when you consider that brand new bikes get thrashed to the limits on a press launch without blowing up, you've certainly gotta wonder just how bad using the bike's full potential can be - as has already been said, it's more to run-in the rider.

I got to admit *sorry, hang on, 1098 going past my work...*
, that i did enjoy the sound of your bike that time you rode past me.

But yeah, I definitely play with the acceleration and deceleration of my bike, just to enjoy the sound, especially in a tunnel...

Actually, I suspect some of the more outrageously extended requirements are intended soley to minimise warrantee claims.

For me, with a modern road engine it’s enough to avoid the top 10% of the rev range and don’t lurk at the same rev’s or load too long.

It's like a whole new riding experience, isn't it?

Not that I am that experienced, but a few people I spoke to told me they were a bit shocked at the difference when riding a Vtwin for the first time.

Ya got to be gentle...make her purr instead of bark til you've got her tamed...Or so I'm told!

And how long did it take you to break her in? Or did you apply the rules of that guy you gave us the link to?

Sorry for going:

You need a set of my custom and highly illegal twin open megaphones on that little VTR.

Like these that I prepared earlier

I thought it was pretty awesome just revvin it wild in the driveway, but the first time I shut the throttle at 11 grand ohhh....

A v-twin with these would just be da bomb, and probably much louder than one!

Warning, these exhausts render the noise dampening effects of earplugs to levels were the earplugs need earplugs!

Back on topic , this issue has got to be the one where you'll here the most difference in terms of opinions.
A highly respected mechnic once told me about running in a race bike at the track from brand new. Two practice sessions, no lugging , no thrashing, changed the oil, full race pace from there and it was the fastest of all of the bikes in that team.
Then the rider rolled it into a little ball!

I didn't, she was "pre-loved".

But yes, as I said I've used that general principle for longer than he's been publicising it. I am a tad more concious of oil temp with a new engine though, some are easy to overheat for a while...
