I know this has been discussed on the forum before and i remember reading somewhere that Ninja service manual suggests replacing the radiator if more than 20% fins are bent.

I had sent my bike for the service,pressure wash led to bent fins,i reported the issue to them,they asked me to come back and they would fix it.
This is what i got back after the repair


I see 40% fins bent here and i am concerned how serious it is,i haven't had any overheating issues by now,so i am wondering if i should-
1)Ask the ASC for a radiator replacement( one person in pune got replacement as earlier told by trustvishwas)
2)Get on with DIY with a radiator fin comb/pliers(BTW where do i find it)
3)See some AC repair centre if they can do a better job with the fins.
4)Leave it like that and forget about it as it wont affect the cooling and wont have any long run leak issues??

Anyways i am shooting a mail to the honda customercare email...I am not expecting a reply from them....So it would be great if you guys suggest me with any option from the above.

I'm confused ; why would you want to report your Ninja's radiator being bent to Honda customer care? Or are you talking about CBR 250R? If its C250R, then why would you want to compare N250R's service manual? Should you be looking into C250R's owner's manual

@nsengg - Thanks a lot mate Appreciate your help

Please note that I had quoted workshop manual and owner's manual.

Oh my Apologies aargee sir,if you are confused you should go though the post once again then....I thought CBR ownership makes it obvious that i am a CBR owner or do i need to mention it in my every post?
AND with Ninja i am just making a comparison(e.g. If its with ninja its should be the same for the cbr)
I hope you get what i am trying to say

Yes sir i remember you making the post,would be great if you could comment on my post with the radiator pic.

Saar...you mentioned N250R's manual!!! Wondering why you're comparing the manual of N250R with C250R. OTOH, would the manual of Boxer 150 & Pulsar 150 be the same?

!!! N250R does 160 Kmph, wonder if C250R does that; N250R yields not more than 25-26 Kmpl if ridden at 120 Kmph, wonder if C250R yields anything in similar or lesser; N250R has a run in period stating RPM limits, wonder if C250R has any such thing on RPM limits. Where's the similarity other than both of them belong to sportsbike & 250cc & sold world wide?

I got it, but NEVER ever compare (or rather confuse) between the manual of one bike over another.

Anyway, let's come to the point - the fins getting bent, if I were you...just make soft ruckus with ASC (since its their mistake) & get the grill replaced under warranty; never settle to get the issue fixed (do this only if you've lot of time)

Meanwhile, take a short ride for about 200-300 Kms (if not keep the speeds in 3 digits & make a 100 Kms run with very less breaks) & keep a tab on the temp guage; at no point, remember, at no ever point, the bars should go beyond 3 & should remain only at 3. If that were the case, then you're safe.

If you want fun, make a short run & keep visiting the ASC, keep making noises (very politely ofcourse, Ji will teach you how ) for new grill under warranty; if they insist you to test for increase in engine temperature, never argue on those terms, simply state, you're not happy esp when the bike is new & keep pestering them for a new one.

Hi docx,

Why not follow ALL of your options in their own separate threads?! Try all the options concurrently and the one which works best would be the area to concentrate on.

About Serial 4, it would definitely affect the cooling, especially on an engine as high tech sensitive and short-stroke as the CeeBee's.

Thanks for the reply, will keep your info handy.

Don't tell me you believed those!!! Question time...
- Were they Indian or Thai makes (hope you know the power & valve differences)
- We don't know yet if they use power box or stock (though claiming stock); I too witnessed 172, but clearly states they used power box.

@Icemang - buddy; no offense meant.

Edit - Just noticed, @doc_x - no appologies needed; peace

I think Sanketh says he has done 171.....lets ask him if he has a Thai made model or Stock Indian.BTW ive myself done upto 157.

Ya and the difference is just of 0.6bhp.

Like I said before, it depends on the gradient; try doing on the same road on the other direction, you may not be able to do 157 again. Rider's weight also does matter here. Try shifting to 6th at 120 & see what's the top speed you get

Apart from Sanketh, someone else also did 171; IIRC its between Salem-K'Giri & I'm pretty confident the gradient works favourable towards K'Giri + he had less fuel. Pls go back few pages where there were hell a lot of discussion on increasing speed beyond 140.

1 Bhp

Even I am having such a radiator (nearly 25% bent) for a long time now, due to the same pressure wash . Still now I have not faced any heating issues, but i fear during soaring summer heat and extreme riding this would show it effects. I tried fixing it myself but could only fix slightly bent fins not the ones completely bent. I hope fixing it with patience will work. Any how much does a new one costs any idea?

And can anyone from here suggest a good mat black aerosol spray if you had tried? I find the mat finish on engine and frame chipping in few spots. And how would it be if i finish the wheels mat black , has anyone tried already ?

Best place to ask

Is Honda indeed coming up with HRC colors for the 250?
