In big words or small, that was what you told me, wasn't it?

I just don't understand how a problem such as that simply goes away without doing anything to rectify it.

Hi,does anyone know what is the ARAI claimed fuel efficiency of CBR?

I dont think there is any ARAI claimed mileage for CBR

damn service guys damaged my bike's radiator fins while cleaning the bike.i always clean with vertical motions of brush...these guys just cleaned it like any other bike part!scrap off left and right!all my trouble of cleaning them with care gone in drain.

on my first service they damaged my bike's dashboard.i got it replaced.now when i give it for washing,they damage the radiator fins!
but will they give a replacement?! i'm just too tired of all the arguments with them.i just want me and my bike in peace!

how much does the bent fins affect the cooling ability?most of the bikes' radiator fins get damged over time,dont they?
and instead of talking to the service centre guys should i call up the dealer instead?
problem is that they did not even charge me anything,so i dont have any receipt as proof?!

Some bent fins won't cause trouble.

UPDATE : Visited the ASC today.Talked with the manager.He said that it is a common problem with all CBRs and that the radiator fins get bent whenever they clean them.He has forwarded the issue to HMSI (i guess he was indirectly stating that the quality of the radiator is poor).
He assured me that the bike wont have any problems whatsoever with the bent fins and that if i'm still in doubt he can just manually repair them for me.I asked him to do that.Left my bike with the ASC.Lets see how much difference manual repairing can make.

cheers.

Wrong!!! It shows how ineffecient, incompetent & illiterate they are w.r.t servicing a C250R!!! Be it even N250R, the radiator fins get bent with pressure wash & they need to do it carefully.

Forwarded the complaint to HMSI is 101% eye wash; if they did that, HMSI will fire back at them asking is that they way HMSI taught their technician.

Manually fixing is what he just did to pacify you, so that you don't make noise with HMSI for the dealer's mistake.

@all concerned about the radiator fin

just because the fins are bent on outside does not mean they are of poor quality.
fins are not meant to be rigid or thick for that matter. A thicker fin will have less heat transfer and will not serve the purpose.
Frankly it does not matter at all if the fins get bent on outside.
There is no loss of performance.

But isn't it true that the fins only guide air through the radiator for proper cooling. Fins getting bend may not have a major effect on overall cooling as still at speed quite a lot of airflow will take place through the radiator. But definitely a radiator with bend fins will not be as effective as one with all fins in shape.

But whatever, the point still remains why the hell they damage due to not taking proper precaution while washing n servicing......
By the way I am also a victim of bend fins during my first service and for me too they straightened them manually.

@techfreak

sorry i dont know how to use your reply as reference as I am new to xbhp.

you got it all wrong my friend. The fins does not guide the air to move through radiator. It is the fin which carries heat from your coolant and the air which comes in contact with your fin take the heat away. So that is how the coolant cools down.
Ofcourse bent fins will not ideally behave as unbent fins but this is real life situation and it is expected that the fins will bent over time.
And as far as the temperature guage points in the right direction no need to worry because the engine will never heat up due this minimal bent fins.

I do agree to what you say, my point is this bend fins should not be due to someones negligence and carelessness or even ignorance.
Thats my point. Especially by people who are supposed to be trained on the machine and are responsible to maintain it.

**aargee** · 09-29-2011, 03:17 PM

Damaged or bent over fins can restrict air flow allowing hot coolant to pass through without dissipating enough heat.

@einzel - Is the above right or incorrect?

And if anyone thinks bent fins are fine, then, I'd personally request you to make a noise with HMSI and ASC; reason being that, HMSI has taught their ASC to wash the bike properly, a little laziness & easy go of us will affect people like us who love our machine more than anything & we too will be taken for granted. Its like saying, there's no issue if the rear grab rails are broken; yes no issues, the bike can still clock whatever speeds it can, but, is that acceptable?

@techfreak - +1 on the last point

1) RVM bolts
2) The rubber which is fitted between swing arm and chain

Let me know if these parts are available at any SVC centre.I will pay the courier charges

Useless thread i guess

You mean the post or the thread

So far this thread is rated 4.4/5 average, not sure how this is useless.

Hope you know you've to pester hard with your/other ASC's in your town/city to get the parts

the answer would be yes and no
As i said it would definitely affect the air flow but efficiency of the radiator would decrease by less than 2% which is negligible.
Again I am telling this to all of you just to sooth you, I understand your feeling, the heart always aches even if there is a single scratch on our beloved bike. I want you to know that it is not as serious as it looks thats it.

But ofcourse that does not mean this should happen because of the negligence of the labourers at the service center. Even I will be pissed off.

By the way arrgee I have been following your tourer posts and I must say that was an extremely nice road trip "fournteen days where......"
