Rich AFR = good performance, low FE, low vibs, higher chances of higher carbon setting in the combustion chamber

Lean AFR = lower performance, higher FE, higher vibs.

Now, m not concerned about the performance here and not even about the FE. So now the equation stays at

Rich = low vibs but higher carbon settlement
Low= higher vibs

Am not good at articulating this question but here it goes

I am worried that the higher vibs at a leaner mixture will damage my engine in some way in the long run but at the other end am also worried that the carbon settlement at richer mixture will also damage it in the long run. So what is better or rather lesser damaging, high vibs lean mix, or low vibs but higher carbon content richer mix

Okay.. a well balanced mixture is ideal.. a lean mixture damages the engine far more than a rich mixture. Cleaning carbon is a piece of cake.. on a lean mixture, you're engine won't last to have carbon deposits.

Is tuning is a must???
be kept with stock... as I do
correct mixture...
will give you good FE & power

Hello everyone! I have acquired an unused Eurogrip tire which is stock rear on the P200NS. I also happen to not need this tire ATM so am selling it off.

If you own a P200NS or know someone who does or would like to try this tire on your bike do send me an e-mail on [email protected].
The tire is 130/70-17 Tubeless so the profile will most likely be very round if you don't own a P200NS but this doesn't cause any problems AFAIK.
Not so good grip when cold but amazing when warmed up (as it is with most tires).

I stay in Mumbai but the tire is in Pune so if you live in either of the two, ping me if you have any questions. Price on request.

Tires aren't meant for shelves so spread the word!

But it doesn't necessarily need to be that way. Just make sure you get the RPM feel and your instincts will automatically follow.

My instincts go "wheeee!!" when I hear the sound of the throttle blipping and the resulting growl after the downshift,but immediately after that my brain goes like this

for subjecting my shiny new bike's gearbox to such brutality.

If you're not familiar with the AFR tuning process,I'd suggest you have the svc guys set the CO setting within 2-2.5 %. Best of both worlds.

If you really love "grunt" why don't you do some cornering up hill, that way you squeeze most of the juice out of the bike's engine, and you'll be even more all smiles.

1) I am poor.
2) I am still poor after tying the first point.
3) Law entrance prep..
4) Not much hills around bhubaneswar with well laid out tarmac to enable cornering.
4)Still poor.

The "krrrrrr" sound from the console is killing my riding experience. Arggggh! Any new tips guys, the svc guys have no clue about it.
I have added a lot of rubber pads around the speedometer area already.

Do a visual check with bike running and just touch base with parts, to see it really helps. By applying pressure on certain areas where that sound is coming, you get an idea as to what can be done. It's either something is touching some other parts or something is loose, or something's loose, fallen and vibrating.

guys am having a prob with the fuel indicator
last friday i got my bikes delivery, showroom guy said that there is 1 litre petrol in the bike, he said go and refill it now just to be safe.
i just put 100rs petrol and reached home. later i filled 500rs more fuel. in 2 days i filled 200rs fuel and again 100rs.
so total of 900rs spent on petrol which sums up to 12 litres of petrol
delivery time odo reading was 10km, now its 350kms.
my question is that when ever am riding now, the fuel bar is empty and after 2 mins of riding it comes to 2 bars or 1 bar.
am following run in period and not taking it above 4k rpm in each gear.
the fuel knob is kept ON, if the petrol from main fuel tank is over, will the bikes engine go off ? or will it run in reserve ? or i have to turn the knob to reserve ?
i feel the fuel knob is faulty, i want to know how many more kms i can ride without refilling more fuel ?
kindly help

First try measuring the fuel efficiency by using the Tankful-to-tankful method and see if the fuel gauge is still showing the error. If it does,it's probably the fuel vapour sensor that's faulty. Get it checked or replaced by the svc personnel.

This problem is almost a given in most P200 NS even worse in 200 NS than the earlier Pulsars, and a case in point was just few pages back. If you keep your fuel tap in mains (not rerserve) and the bike stops. You still have more usable 3 liters left, which can be used (after the bike stops in main that is) turn it to reserve and use the avlbl fuel.

Now if you directly keep the cock in reserve and the bike keeps running till the reserve fuel gets used up, then there is no chance to get your bike started. You have to refill your fuel tank.

It's always a good practice to keep your fuel cock in mains. No matter what the gauge displays, always trust your fuel cock as a guide to actually judge your actual mileage and fuel efficiency.

@Aytas sss, blackthorn
thanks for clarifing that about rev match downshift ! I've been doing that alot since past 2 weeks and am getting fond of it. It's just that downshifts are super smooth with this method, you don't feel the pulling force in low gears like you do normally. and the sound is just orgasmic. When riding it feels like you're meant to downshift in that manner (cause someone here on xbhp also stated this) But I had no idea this isn't a healthy practice for the engine.. I thought bike engines are built strong enough to handle this. What kind of wear and tear are talking about here ?
So basically no matter how fun it is, I should stop this practice for the sake of my bike's engine ? and tolerate the normal thud noised downshifts ? :s

who told you that 'blip' downshift was bad for the bike/engine/gearbox ??? when you do the rev match correctly (without locking up the wheels etc..) it is perfectly ok and infact better than just rolling off the throttle and going thud thud thud downshift!!
what you have been doing until now (rev match and downshift) is perfectly ok, so keep practicing and perfect it.

I have been doing this almost ever since i started riding a geared motorbike and picked up this method on my own after a few months of riding (call it a 'eureka' discovery).. it just felt right and smooth. and have ever since been doing this on all the bikes i have owned/ridden without any issues. only much much later on did i realize that this was what was called 'rev matching downshift' (unfortunately i did not have the internet penetration back in the late 90's - early 2000's to learn much about this method)

to all those involved in the prev few posts on this 'blip downshift' discussion:

Read this article Throttle Blipping for Downshifts and this http://www.motorcycleforum.com/showthread.php?t=93609 - you may learn a thing or two and improve your technique.

Small correction, its about 2.4-2.5 ltr in reserve. I have checked it many many time. From reserve to dry tank method..:P

@all,
I find the p200NS digital fuel indicator good enough. In my passion its a little better. But i guess its just about as better as it can get.

Recently got fork oil + springs changed(as told to me by SVC, don't believe them much though).... THe SVC manager is saying its absolutely normal..... :@ what is irritating is for everything they say its normal even though they themselves know its not.... they just dont want to acceot it... :@

Any suggestions on this? I am still facing this issue, had left the bike for one whole day at SVC and according to them they have replaced fork oil and springs, but i am still getting the issue. They have asked me to again leave the bike. I am f***** tired of visiting SVC every 2-3 weekends, why cant these idiots work properly.

Also the front brake losing its bite issue, which i had mentioned few weeks back, got the brake pads changed as they had worn out. But still the front brake doesn't seem to improve as it was when the bike was new. Any suggestions here too?
