Please talk to the people who have had engine seizures whilst running the KnN! In most cases it has been dirt. That issue can be reduced by a bit if one uses a foam wrap on the filter.

Stock replacement filters typically should not have this issue. But then again, is the cost/performance gain ratio justified ?

The major sign is when the rear wheel is moving sideways, it's time for a chnage. I have to get mine changed in the next service.

yes, I guess it's the second or 1st time I am getting this part changed. They don't actually do these greesing since the whole rear wheel needs to be taken off.

Cost/performance gain ratio is a tricky issue and a clever question praful
I'd say no, its expensive 2,750 Rs here in pune and it would cost more as mileage would go down by about 1-2 kmpl but on the other hand performance is better in a free-flow than a restricted foam flow...
Its a tradeoff, anyway no plans on buying this filter for the near future, the 8.50 Rs increase in petrol prices killed my enthusiasm for this damm filter

it in no way is justified.You pay some 2500/- odd bucks for what ? getting over heated engine and risk engine seizures ?
and assuming a teeny tiny increase in mileage(if any) ?
And whats in a small sound increase with no increase performance ? Trust me i have a very loud one(Race concept FFE, but that s a different story)

A FreeFlow Air Filter might let the engine to breathe in more freely , but then the fuel must also be adequately adjusted. Else itll run lean and the engine heating starts. So it again begs the queestion, is it worth it ?

actually even i hav seen that 220 in bsk probiking think it was red 220.

Ok folks, just had a chat with my trusted PBK supervisor.

The rear sprocket bearing is meant to last and will give up only if :-

1. Have been riding with punctured tyres
2. Is running over inflated air pressures
3. Regular greasing has not been done.

And I agree with his logic, because I tried real hard to recollect when all I have changed the rear bearing. So far been only twice.

And, the first instance it was definitely post the 35K kms mark and the next time was definitely around 60K mark. And now it wore out @ 87K kms. So I think it'd be safe to assume a life of 30-40K kms. If you haven't changed it in this much time, I think its best to replace it as preventive maintenance. It barely costs 90/- bux


@Krish: Huzee was talking about the stock replacement filter, which is not a conical filter. The risk of dust/tuning going kaput on that is fairly minimal, but then at some 2.5-2.7K the cost is not justified for minor gain in throttle response. I think air filter changes are only warranted when there have been other changes in the system which demand more air/fuel into it. Until then its a well balanced system and is best left untouched.

@Huzee: How much is the fuel hike actually impacting us?

Assuming the following :-

Bike Mileage - 35 Kmpl
Kms/Month - 1500
Fuel Rate - 74/Ltr

Monthly Expense -> 3172/-
Monthly Expense after 8 bux increase -> 3514

Net Difference -> 343/-

How do you spend on a movie ticket/CCD coffee/baskin robins ice cream/bottles of beer? Is it really that bad?

And Krish, bro you've been all highs about the FFE and stuff, and why all of a sudden you have a such a gripe?

You've mentioned it clearly that running either lean or rich cause heating issues, and it's even more evident in Fi considering, even a slight screw up in ECU leads to crazy bike response.

Being DTSi I think, and moreso you've been *all highs* about the FFE as long as you don't see the temperature indicator lit, you're all set.

No mate, I've personally changed my first set of rear sprocket with chain in my Victor at around 30k and trust me it lasted helluva a lot of whipping and it still had some life in it.

Now Rolon being the supplier of the chain for both, personally I reckon it's best to change the sprocket set after 15k depending on the wear and tear.

And 5k to 10k for the chain set, again depending on the usage. I am very sure, improper lubing, adjusting and driving the chain can lead to significantly reduced sprocket and chain life.

I've personally seen Bajaj 180 cc sprocket gone in just 10k Kms, but don't ask about the guy, that's a completely different story.

Lubing, tightening (to the correct slackness) too tight or too loose is all gonna adversely affect the life.

But then, you're right, it should last between 20k to 25k.

Cheers!

Not really. If the sprocket is sharp as saw,then it's time to change I guess, if it's flat and blunt, you still have long ways to go.

Now you should be knowing this antz, being the guy you are. Tightening, lubing and being prudent in understanding and avoiding unnecessary whiplash caused when the chain is getting loose.

Nice on emate, but notice a few point here.
I mentioned Free flow Air Filter and not Free flow Exhaust, as you know one is for breathing in air, and other is for breathing out the gases. So irts pretty much completely different deal.
So while breathing in(air filter) if you have more air and less fuel your running lean and heats up. Right ?
Now while breathing out(free flow exhaust) if you breathe out easier, all the residual gases easily exits the chamber, and not to mention the gases are very very hot, so making them go out faster makes it lesser chance for cooling down the engine. After the FFE mod i have never had any problem with over heat dissipation even at triple digit runs. And moreover the cooling is faster too.

Cheers mate

Chain Sprocket maintenance I obviously know. I was talking about the bearing.

Praful indeed was so quick, he even called up the PBK guys and asked them about the maintenance of why and when the bearing goes kaput.

P.S. Thank you, Praf.

Cheers!
VJ

Thanks for the update.

I know it is not much, but it is higher than earlier hikes. Earlier hikes were covered by avoiding a coffee at The Moto Cafe . But this time around, it is equivalent to 2 movie tickets . I mean I watched only 1 movie in last 1 month, how to watch -1 movies now .

Exactly Krish. Irrespective of whether it's FFE or free flow air filter, all things said and done correspond to one thing, suck in more air, and suck out more. And I clearly noticed your point bro.

If you look why I mentioned FI and go back a few pages, Praful has answered your same query in *huge chunks* regarding your query. No problem mate, as long as you are carburetted, you're on safer side.

Cheers!

Nope, I have actually been at PBK all day today. Have been Working from PBK today lol

Decided to have my PBK fellows open up the bearing and redo it again as I din't trust the other Bajaj place where I was forced to go yesterday

Agreed, But this has to happen once in a while. I remember something similar had happened in 2008 when fuel went up from 51 to 57 and in Shell it used to cost almost 65 then. Oh! What hue and cry!

Wait for the torrents to come out and watch it from home....lol..Just kidding bro.

LMFAO! Way to go mate, way to go!

Forgive me for the filler though!
