Cool Running

[Zed]

There is a lot of talk out there about how best to run in a new bike! I would appreciate feedback from those who have had the pleasure of purchasing a brand new bike and running it in- what has worked for you?

Personally I have only bought one brand new bike, a CBR900RR fireblade in '95, and I ran it in by the book...the first 2000kms were very boring! My approach on the next new bike I get will be to ride it like I normally would (giving it death at times ) but not redlining it straightaway! I am a firm believer that the more you work a bike the better it goes, regular maintenance & orderly riding practices taken into consideration.

Only ever had one new bike,Suzuki GS850G.
Ran it in just like I rode it,Don't let it labour an don't cane it.
First oil change at 100km an after that as per the book.

Check it out for some alternative views on running in, look at #9. Plenty of evidence to support ideas.

Even big 4-stroke race bikes I've had, including a turbo, I've always followed more or less his ideas and never had a problem. A friend has a 8L blown drag car. From new the motor is warmed up then cooled before retorqueing the heads. The next time it's started is to race. It does 9000rpm through the gears and over a season the leakdown just gets better and better. Never a problem with bores/pistons or bearings on the bikes or car. Even on my little 2-stroke bike it seems to be fine, round the kart track anyway.

Thanks, that method sounds logical.

Hi Zed,

Racing spannerman over in Taupo told me to do this:-

- Don't let it idle too long.
- Don't let it warm up for more than about 90 secs (different for particularly cold mornings).
- Don't rev the nuts off it (I interpreted this as 'don't redline it').
- Don't labour it.

Apart from that he said ride it straight out of the crate like ya gonna ride it (which is also open to interpretation). Just give it good bursts of acceleration and deceleration to produce those high pressures to achieve good component mating between rings and cylinder walls and therefore good compressions.

Nice bike Zed. Enjoy brudder!

not quite sure why you wouldn't let it warm up really well anyway tho? I wait till its up to 50' before trundling off (and 65 at least before opening the tap much). certainly warm up is crucial to preventing engine wear (and thats something that all parties agree on)

zed... i'm guessing yours is an ex-demo? could well mean it has been babied a bit by test riders (CBR's being a decent tourer and all) so it probably needs a damn good hiding to get the compression up in a big hurry! (if not, what the heck... its a good excuse if ever there was one!)

Nah, I was told that it was sold brand new to a 19yr old whose parents made him bring it back...he clocked up around 1600kms on it.

And as for a good hiding...well...already done sir! twice That spurt out at Pukekohe last Friday transformed me a tad! I wish I had the CBR then...

[Coldkiwi]

hehe, glad you enjoyed it. Puke is much more enjoyable with a stable but nimble front end and I imagine the CBR should give you more of that over the zx6R.

poor kid having to bring it back tho. he would've been over the moon to ride one of those I'm sure

It is usually better to warm any vehicle up by driving it nice and calmly until it is warm, so therefore letting it warm for no more than 90secs and then ride down the road nicely for a bit should have it warmed up in about 5min or less. Thats if its not to cold out there.

I might seem like a dick asking this but i cant quite make my mind up completely on wut u mean by Labouring so please explain.

Thanks

"Labouring" is the term used to describe a good honest days work. Something you wouldn't know too much about I'll bet.

Or, to describe over loading the engine. Such as trying to ride your ZXR up the Wainui hill in 6th gear at 50kph.

[riffer]

Nah you're not a dick.

Labouring is when you are using too high a gear for the speed you are doing ie the revs are too low and you are using too much throttle - you know - it sounds really "laboured". You might also get chain snatch too when this happens.

[mangell6]

With the FZed1 I read the book then applied the uncommonsense approach as outined by many above. I ran it past the rev limit that the manufacturer rec'd and then back down again, did not hold the revs above the rec'd limit for long. I did not 'cane' the machine until 1600kms and then it was all on

Chevrolet did lots of very careful tests on a lot of cars over a lot of miles to try and determine the best option re warming engines. Half got the get in and drive away treatment, the other half got warmed up before moving. Engines were stripped and measured and no differance was measureable.

I had an oil temp gauge on a modified Z1 and even after warming it up and then riding off at a fairly brisk pace it still took about 10Kms for the oil to get close to operating temp. The engine felt warm/hot well before then. Based on that, even those who warm their engines before driving off don't allow enough time for the really important bit to get warm. Plus Chevrolet found no benefit, which is not to say you should fire it up and redline it down the road immediately, that wasn't what they tested.

If the CBR's already done 1,600 km's, talk of running in seems moot.
Just ride normally.

My concern is that it hasn't been run in properly and may never perform to its full potential? :sneaky2:

Hearing others views about running in new bikes was my main intention when I started this thread.
