cheers.

^^^ Aniket - Make a low tone ruckus, talk firmly with ASC to speak with HMSI engineer & you WILL be able to replace the radiator under warranty.

Guys, anyone installed iridium spark plugs..? I need the exact version of it. And also k&n filter suitable for CBR. My friend wants to install them, so pls tell me the best options...

Pls share us the reason & benefits as why an iridium plug is preffered.

@aargee-
Could you please help me understand the difference between a noisy and a rough engine. I cannot seem to decide what behaviour mine exhibits.

Also, I do not know how to identify tappet noise.

Rough engine - When you accelerate, you tend to feel the engine is slightly beginning at the stage of stress no matter what speed it is, but certainly not higher the speed, higher the stress type. The sheer smoothness of C250R is lost. When you change the oil, you get back the smoothness.

Noisy engine - No stress, nothing, just the engine sounds a little loud.

This is worst, but would sound something like this...

I don't think it's either of the two.. Engine obviously sounds stressed at higher speeds, and is also pretty noisy above 8k, but that is to be expected from a single cylinder. Also, I get FE of about 22 km/l, but that might be due to the fact that I'm kind of rev-happy.

I'll keep an ear out for tappet noise the next time I go for a ride.

Thanks for the helpful reply.

Too less; but if you REV every single ride you take it out, then the FE MAY be low; I usually rev after the engine is warm, but not more than 6-7K RPM at every gear. Even with that I get 29.xx

You don't need to; you WILL hear the additional noise even when the engine is running idle. I'd say don't rev past 8-8.5K RPM & you won't hear tappet noises or experience engine issues for quite longer periods.

Iridium IX Outstanding acceleration, high fuel efficiency and durability. Ultimate design, technology and performance.

**aargee** · 09-26-2011, 11:21 PM

^^^ That's fantastic; now, pls share us by how many percent we can expect a performance gain on using iridium plug on C250R over the stock one? And what would be ratio of the performance gain to the price of iridium plug?

@trustvishwas had advised me to rev a lot for around 800 kms, in order to open up the throttle. Got about 200 km left out of that. Once that's done with, I hope I won't be revving so much (unless I'm too used to it by then).

Many thanks for the advise given by Vishwas ji. It's opened up the throttle a lot, but engine doesn't feel as smooth as it used to earlier. Don't get me wrong, I'm completely fine with that. A little loss of smoothness for the amazing throttle response I get now.
Someone many pages back, had said that I should change oil filter after I'm done with this 'second break in'. If it's required, I don't mind doing that.

As if I have used it.

It would be obviously better than stock one...

For Example, since you don't understand things easily --

Normal Plugs are - Normal Intel Pentium 4

Iridum IX plugs are - 2nd Generation i7

Change engine oil + filter & things will be back to normal

Its not second or third break in, just change the oil filter, if its affordable with every oil change (may not require after 10-12K on ODO)

And this is for Shubi - Don't break your head further, I'm aware of what an Iridium plug is & what it can do. FYI, C250R stock spark plug is NGK SIMR8A9 & its a Iridium plug. So unless you've lots of money & not knowing what to do, you can go ahead & replace the stock iridium plug with AM iridium plug

I can understand your pain! There are vibrations in mine as well, but not that noticeable. I guess they have made this bike to be ridden in cities only..wax it up...cut through traffic...maybe have a photo-shoot or two

Out of 8k, 6k have been on tours...I am still waiting for the the tag "sports tourer" to justify itself!

Folks, you guys are scaring me. My R15 would be gone in a day or two & have already made a booking and the bike should arrive in 2-3 weeks. I would be making the payment, if & only if the filters & shims are available. But what am I supposed to do w/o a bike? The issues being reported aren't exactly blown out of proportion.

Originally posted by darkknight View Post

atleast you are getting the shims.it's been over a month here without them.but no tappet noise in mine but killer vibes

disc pad I guess are manufatured in remote parts of africa as with other honda spares so not their fault that it takes foreover for materials to be arranged.
my svc went ahead & enquired all hero bikes pads & even checked to see if they fit

the clutch lever nut fell off in the middle of the road (probably due to vibrations) & I had to go to hero for it since honda doesn't keep those either
all in all my frustrations have given way to amusement but dunno how long am gonna continue with this bullshit

I dont think you want to know the exact gain. Are you trying for some show off, man? I thought aargee was a man who knew something about bikes and so related things. If you want to know the exact gain, why dont you put it yourself(on your bike) and see it..? Riding CBR for a 10k doesnt mean you know everything about it.. or its a pain in the ***. Many do change their stock plugs and air filters. Its a personal choice. I asked if anyone has used a better spark plug or k&n filter, so that I can easily get that one. Have you got Piles or something? Cant sit quiet? If you dont know anything(which you pretend) or you think you know too much is a very bad habit. There are many other cbr owners here who can speak. When asked about spark plugs, blah blah blah ... is not the answer. I think you are the owner of Honda itself. Sir, you know everything and I think you are not from this planet... Good Night bro..

Its about time somebody noticed this...! And responded...!

@aargee...take the criticism in a positive way. Its only gonna make the forum more member-friendly.
