dude, Its not the same for everyone. Atleast for me & Rohitmundra. mine also has done 22k kms and still the sprocket and the chain of my 200 is healthy as seen by me and also Pro-Biking people Sometimes u cant find a reason for it...! Just have to take it!

Well, i am sure it surely depends upon the lubricating intervals and yes how much city and highway rides you are doing on it.
Usually i have seen people who goes for a long rides often, ripes it often..tends to get the chain loosened more quickly...causing a need of frequent lubrication and in the case of missing the interval...shorting the life of chain - sprocket.

Agreed, but mine clocks 600-700m kms a week but not to forget, i lube the chain regularly once in two weeks, maybe that care would have resulted in that extra life of the chain & sprockets!!

Its all about taking care of your chain, lubricating it at regular intervals(500kms)

gear oil has no side effects infact its recommended by Bajaj only in the manual and it comes on the cheaper side too as compared to chain sprays. only the negetive point- the oil sprinkles on the mags, but that can be cleaned.

I never got the logic of people spending so much on chain sprays for chains which costs around 1.5K only! And it is not like chain sprays extend the life of chains dramatically by twice or more. Gear oil does just fine! Atleast you are not using burnt engine oil!

I said "the bike does rev all the way to it's ~11K redline" not beyond, i don't think the bike revs more than 11k

That is news to me because AFAIK, Bajaj never had a plan for performance kits, there were talks about TVS coming out with it's performance kits but that too is yet to see the light of the day

Re-jet is a must if you are going in for free flow filters, because the standard jets are just not enough to let in the excess of air taken in by the filter, therefore the fuel mixture becomes excessively rich choking the bike and heating it, also cold starts would become a problem and performance would drop instead of increasing, the stock jets on our bikes are 110 size, therefore you have to up-jet to bigger ones.

Iridium plugs are available on NGK's, the Iridium NGK for the 200 is "CR9EIX", you can also check out this site and find the respective plugs for any bike here >> NGK Partfinder Catalogues

As per the manual it specifies us to use an SAE90 gear oil for the drive chain, refer page no. 20

The chain may cost only 1.5k but a ill-maintained chain can screw up your gear-box too, a well oiled chain can not only protect your drive-chain but also the gears and ensure the life of your gearbox too, not only that it'll ensure better and smoother gear-shifts. And the reason for opting for spray instead of gear oil is because spray is a lot thinner and sticks better to the chain and sprocket than the gear-oil which is thick and messy, and the gear-oil will not last as long as an chain spray. I had overused my spray once by nearly 250kms and it still held good

You got it opposite! Rejetting increases the flow of the fuel. Custom air filter increases air flow which leans out the mixture. To undo this, we use bigger jets. And excessively rich fuel mixture does not heat up a bike - excessively lean fuel mixture does that!

And regarding chain lubes, gearbox may be affected but not much if you keep the chain slack proper. And what I meant was that gear oil is also equally good. Use of chain spray is not really justified!

I agree to this, as i was not satisfied with the chain sprays during my early days in my 200 which will last for a very less time and also the chain spray tends to make the chain & the sprocket dry after a rain and i've experienced this a lot of times which gives out screeching noises. After switching over to 90 grade gear oil, the chain and the transmission had become butter smooth and also tends to stay for a longer time and also is not as expensive as the sprays. The only disadvantage in gear oil is that it leaves residues of oil in the rear alloys which can be cleaned easily.

Aw god damn it not again!! OK, Less air=Lean mixture; More air=Rich mixture, Cool thanks for the heads up man

I think you got it wrong again, More air (result) = Lean Mixture and Less Air (result) = Rich Mixture. So when you put a K&N in stock there's more air going to engine on stock condition hence lean mixture, with the more air you upjet, that's to compensate, now you also add more fuel, balancing the mixture. But the fuel consumption is higher!

+1 , u r right man,

LOL!

ELD, bro, I think you are overworked.

This is what you had said.

Free Flow air filter increases air flow which increases air:fuel mixture (becomes lean).
ReJetting will increase fuel flow negating the above effect.

i din understand wat re-jetting is!!
how is it done???
my first bike!!

Guys i just got saved from a freaking fall .....i hit the pothole hard at 80+....No bends or cracks on rims . !! f**k man i got really scared that my bike might have taken the beating...its awesome as usual...and i was not wearing a helmet too....i regretted a lot later though !

My frndz captured it too !! http://www.youtube.com/watch?v=HnndywIon4g
