whoa!! my query has gone for a heated debate!! i think each person will have their own input and i appreciate everyone's effort to making it clear the reason i asked it because it was not mentioned anywhere in the manual...so had some doubtson run in (i previously read about run in here few pages back), later i found the dealership had ripped 3-4 pages from the manual anyway thanks guys for your inputs cheers!

Yes, each person will have a different opinion but all of them can't be correct. I hope you got to know which run-in you should follow from all the so called 'heated' debates.

And the silver lining is 'Next time onwards,everyone will read the manual before asking questions'
Although I wonder why on earth your dealer would rip those 3/4 pages ?

Anyone can u clarify on this???

Machining of internal engine parts didnt achieve exact tolerances earlier when technology was not that advanced. Its now different a story altogether, hence even if you ride at say 6000 RPM during run in, it wont be making any harm. Its as simple as that.

I think what you are experiencing is because you have a pillion the weight increases and you have to rev the engine a bit for it to pull from being stationary/slow. This happens with engines that are rev happy (unlike royal enfields) and not torquey. But I think yes unless you are going down the slope or are in a momentum already your bike would rev more at a lesser speed if it has a pillion/heavy pillion. So I suggest you keep your run-in limited in reference to the rpm's and not the speed if you ride with a pillion a lot.
For example: Eshan weighs 100 kgs and Kuntal weighs 30 kgs. At a particular rpm eshans bike runs at 127 kmph while kuntals bike runs at 140kmph at the same rpm.
The above is not purely theoretical but was experienced by us on a ride.

I broke in MotoMans way. Took my bike to 125kmph / full throttle and ripped it very hard when the ODO was 20kms or so. And then i put minarel oil @100kms and changed it for 1st service only.

Like Somen explained, there is 2 methods you have for engine break in, manual & motomans. and obviously the end result will be different with each other.

i broke in motomans, my friend broke in traditional.
now@ 10k on odo (both bikes, and even before) mine has far more grunt, his bike is too smooth, the two bikes sound very very different.
his bike is smooth hence has a feeling of revving easy and being easy to ride. where as mine has a wild feeling, it sound very louder over 5k rpm and pulls very nice.
i think the major noticeable difference is only this much.

We pulled some drags but no one had any advantages, it was neck to neck.

the main difference is the feel, @ 5k rpm my bike feels like it has lots of power in store and the throttle response/feel is very torquey where are his ride even having the same power, it doesn't feel so.

Any of you broke in the manual way can test my bike and you will feel the difference, (i am saying its different, not better. ) and the choice is owners.


And do you think even if Yamaha finds out that Motomans way is better, would they print it on the Manual. ? NO... its too dangerous considering the owner/buyer is new to the bike.

And even if they print, a lot of people will not buy this bike just because they cant break in.

Not everyone who is buying an r15 need the motomans method.
Its upto your requirements,
I have shared my result, if anyone else had broke in this way, please share the result.

Re: Yamaha YZF-R15 version 2.0

So you broke in using the motoman's way and you got a rough and noisy engine
Most people love smooth fast revving engine, maybe thats why Yamaha recommends 'soft break in'

Grunt isn't noise .
Maybe you should try electric bikes then, smooth and silent

you must ride my bike and see the difference, trust me, you'll love mine more.

Re: Yamaha YZF-R15 version 2.0

No, in your case I said grunt = vibration. Noisy= you said after 5k its louder.
Btw I love loud exhaust but not a vibey engine

UNBELIEVABLE.. you guys are wore than media these days..
Dude... you read it as you want. you understand as you want, you break in as you want.

An when did grunt become vibration ? he he...
and also loudness inst noise.
@ busy traffic, the place is noisy (hope its clear, the place is noisy not my bike above 5k ) and @ a Metal concert its loud..... (please note its not my bike that making the sound )

"Promote what you love instead of bashing what you hate." just now i saw this. UNBELIEVABLE..

Chillax both of you...Its just a discussion, not a war.

Btw Christo which bike do you own? i hope you know there is a huge difference between R15V2 and a Fazer150!

Re: Yamaha YZF-R15 version 2.0

I think you're wrong there. Same RPM and same gear = equal speed regardless of the weight. The only possible thing is that the machine with more weight takes more time to get there that's it.

Re: Yamaha YZF-R15 version 2.0

Chill bro, got nothing against your ride
Even after hard break in your ride doesn't have any real advantage(only feel) over the bike that done a soft break in.
Btw I never said what you did is 'wrong' or 'bad'.
Peace :beer:

Edit: I converted your 'grunt' into 'vibey' because after riding r15 the apache felt it had more 'grunt'. In reality ..not really, all that vibration makes people (at lest me) think that way.

In strict theory what you say may be true. But we aren't talking about theory and science, are we?. In practical riding scenarios where there are inclinations and pillions; a rider if he tries to maintain the same speed in all conditions he is bound to exceed the run in rpms at more than a handfull times. Unless again you expect him to be a swami who is patient enough to not raise rpm and continue to drag at the slow speed and low rpm till the speed to be followed is reached. Try to get the context of my reply to him in regard to his query on run in.
