Okies.....so may be dazzler is having a fuel screw, but it still needs to be 100% confirmed, I guess.

Dazzler has the fuel screw. Turning clockwise reduces fuel flow making the AF mix lean, turning anticlockwise increases fuel flow making the AF mix rich.

Please note that this will affect only the tuning for the pilot jet i.e. AF mixture upto about 3000 rpms or 1/4th accelerator twist.

FYI: Stock setting is 2 and 1/2 turns out from full close. Setting on my bike is 3 turns out from full close.

Thanks a ton, this is what I wanted to know.

Btw, I would be glad if you could also throw some light on the following issue -

Btw, today I inspected my front disc brake pads properly with a help of a small torch. I noticed that the inner pad (one which is closer to the wheel & away from brake piston) has worn out a lot compared to the outer pad.
Last time also when I changed my front disc pads (@ 25K odo) the inner pad had worn out completely while there was very little wear in the outer pad.
At that time my mechanic checked the brake pistons & made sure that both the brake pistons are moving freely.

So, what could be the reason behind this uneven front disc brake pads wear? What should I do now?

Actually I had read this post of your previously but did not say anything cause unfortunately I don't really know what can cause this kind of wear pattern. The only thing I can think of is different brake pad material but that is definitely an extremely unlikely reason so that's why I did not reply. Anyway I will keep an eye out and may be ask a few local mechanics and let you know if I get something concrete.

In the bike, the piston is located at one side of the caliper. When we apply the brake, pads of the side which has piston comes in contact with disc. Then as more pressure is applied the mounting moves which makes the other pads to come in contact. So this fraction of second is what causes one side pad to get worn. This is the reason why discs are known as floating discs. If you notice, the caliper is not solidly mounted but is mounted on rubber boots which slides the caliper causing the pad to touch and separate.

This happens if the floating Caliper is no longer floating but stuck.....you have to lube the stay stems to keep it in good condition...

Correct, but his inside pad is wearing off faster (if I understood correctly). That's the one which comes in contact later.

Correct, in my case inside pad (one which is away from brake piston & comes in contact later) is wearing out faster than the other pad (piston side pad).

Now I need to go for pad change very soon, so what precautions i should take so this uneven wear doesn't takes place again.

I guess the contact points (ref picture by divya sharan in previous page or below) may not greased properly which is not facilitating the release function properly thereby the pad constantly sticks to the disc.

This time when you replace the disc pads have the following checked;
1. Dust covers are in upbeat condition that does not allow dust to mix up with the grease
2. Ensure the caliper is not bent anywhere
3. Change the fluid/fluid pipe if necessary - even if the fluid pressure isn't appropriate the pads will not spring back to its position.

Okies.... so now, what I understood is that after releasing the brake lever the inner pad (one which is away from brake piston & comes in contact later) is somehow not getting released & keeps rubbing the disk for a while which is causing it to wear faster than the outer pad (one near to piston & comes in contact earlier)

So, for this I need to clean & lube the stay stems/contact points ( as shown in pic by divya sharan) along with fluid change & inspection of dust covers & caliper during this pad change.

Am I correct?

Note: My bike runs very freely on slopes (in neutral gear) even after repeated applications of front brakes. I mean I never felt any kinda resistance or drag in free rotation of front wheel.

Also, as per the explanation given by Divya Sharan, bike's piston side pad should have shown more wear than the inner pad. But, it's other way round in my case.

Never run downhill in neutral/with engine off.
Get your brake lines checked and bleed your brake lines again with fresh DOT4 oil (preferred) or DOT3 oil. Ensure that there are no air bubbles.
What you're facing is due to presence of air in brake lines.

Everybody installs tyres for riding purposes only

BTW, what is your 'riding purpose'???

Of course, I know how dangerous it is to run a bike downhill in neutral, I don't follow it as a practice, it was just for testing purpose.

So, now I will go for complete front disc brake overhaul with brake lines bleeding & will update on this here.
Thanks divya sharan, plasmabhai & petrolhead_chn for there inputs.

Btw. I am having a hard time sourcing the stock front disc pads at all honda svcs in my area (though I managed to source rear disc pads at a whooping mrp of Rs 865/- only which I may have to replace in next 2-3K kms or so, current odo 42.5K. More on that later).

I even tried for hero moto's hunk/extreme pads but no luck. They are not in stock currently, need to wait for 5-6 days at least. So what i want know is are there any better alternatives than the stock ones?

That seems correct, even I bought a set of rear disc pads for Rs.862/- day before yesterday, original Nissins are damn costly man..!! You can also go for RTR160 front disc pads as well. I think they are Rs180/- a pair but don't quote me on this, price might have increased/changed.

Not really sure if there are any other "BETTER" alternatives. Best thing will be a perfect bleed using new DOT4 fluid in brake lines with zero leakage. That will seriously improve your braking. The front brake pads from R15 are also from Nissins and so similarly costly but they are a better alternative without a doubt. However am not sure if they fit our dazzler's front KBX brakes.

Grr, Dazzy's and R15's Nissin pads cost only 860 odd? Damn man, ZMR's cost 1300 for front and 1250 for rear!

Ok, coming to alternatives - Apache RTR's pads. They're dirt cheap - 190 odd. Don't bite as much as OE pads. Life around 70% of OE.
Another option is Shriram Alpine brake pads. ShriRam Alpine Group

I got this info from [MENTION=32286]psr[/MENTION] sir. These are better than Apache's in terms of bite but less than OE. Prices are almost half w.r.t OE.
