Well I will be changing at first service..motul mineral
Many riders have done it at 200kms, some at 100 kms. So it's upto you. But the most important thing is to not to put Bajaj oil, totally not recommended

Your denial of 200NS's top speed figures, should be taken as a compliment. Also i'm not sure, how are you calculating the top speed of the bike, without taking in consideration plethora of other variables. CBR250, makes it's peak power at 8500RPM and reaches a speedo indicated top speed of 165KMPH. Secondly, the rev limiter in 200NS kicks in just before 11K RPM, with favorable conditions any 200NS is capable of crossing a speedo indicated 150KMPH without any drama (how stable the bike remains that's another topic).

IT DOES! NS has a rev limiter cutting in gradually just before 11000 RPM. And unlike Duke, the rev limiter is mild and does not hold you back for long.

Sure! What about your issues. any updates?

Thank God people are not comparing Top End Bikes with Low End Air-crafts

Top end bikes are capable of out running low end air crafts! If anybody has doubts let me know

Thanx for quick response.

The part in bold in your quote: It goes against my intuition. Thin oil should reduce idling rpm as it would reduce the friction in the internal parts. Also putting a 15W20 oil in NS reduced idling rpm in my bike as against what it had when it was running on 20W50. Please enlighten me on this.

As you say thin oil reduces friction of internals, so the parts can move freely..and hence all things being equal(only oil change) the engine can move easily and more than before......which is increase in RPM...
Your DTSi oil was actually thinner than the 15w50 you used, hence reduction in RPM,with new 15w50 oil

hi... everyone... after my first service of 790 kms i took my pulsar 200ns to highway towards 180km up and down in that travel i seen the bike hit top speed of 120 km/hr @8000 rpm regarding it i call'd to the pulsar service man that too he is my friend told me that we limit the engine speed to 7,500 in first service later after two service it can capable of going apeed anything in 9500rpm i'm bit confused in it can anyone help me out my mileage is 35kmpl 5.50 ltr for 190 kms is that good mileage ?

Your friend in the service center is just fooling around or is ignorant. There is no such thing as "Limiting the engine speed" for the first few services. If he does that, he is violating the law by fiddling around your bike & not informing you about the limited speed, when you purchased the bike.

All that apart, probably the AFR tuning is needed and also the engine is not yet completely free revving. So dont worry about the speed, but check if your engine revs freely till 10,500 (but i suggest you do this only after second service). If the revving is free & unrestrictive but the speed is low, then raise your concern.

OK now I am really confused.

1. DTSi is 20W50 right?? then it is suppose to be thicker than a 15W50 oil. Its thick at cold temperatures while at hot temperatures both should be behaving almost the same.

2. Regarding RPM, well if the power produced by engine is constant say, then reduction in internal friction (that is reduction in work it needs to do just to overcome the friction i.e reduction in required torque in other words.) should increase rpm.

POWER = TORQUE * RPM ........... so when Power remains constant, reduction in torque is compensated by increase in RPM.

(One question , do the engine keep producing same power even if the internal friction is reduced?? I think YES..It really depends on the AFR)

So if 1 and 2 are correct then when i put 15W50 in my engine, keeping all other parameters constant, I should be seeing increse in RPM right?? On contrary RPM actually decreased by about 200.

All my NS friends -
My Father got ourselves a New Car (XUV 5oo) yesterday. Since this is a Biking forum, so will not go into details, but just a Small teaser of the Beast along with my Darling DESTINY.

PS -It is absolutely a co-incidence that I'm putting up this post at a time when there have been an ongoing Bike vs Cars discussion going on. This post is just meant to share the good news, and my love/preference stays with MY Destiny.. (any given day)

Congrats on the XUV...

BTW if anyone is interested in reading about my first day ride when i did 760 kms from Mumbai to Hampi on my NS, please head click below:

Prologue and Day 1

On other news Lets put the biker vs Driver thing into permanent rest.... :P
I, the biker, promise that i will not spoil the sanctity of the 200NS thread with such OTs in future.
Apologies, that I started this, I should have PMed the fellow biker rather than posting here...

Don't change the oil now. Let it run for another 100kms or more before you change to Bajaj DTSi/Castrol/Motul. Reason, The oil that came with the bike, helps in engine in the initial time for getting used to the running conditions and all the parts <I forgot the exact word>. 300~500kms would be the ideal time when one should change the oil for the first time.

@Regarding Brake Lever Issue (someone had asked)

I tested an RTR today with the same issue just that it was little grave. Generally this is caused due to an excess of air packets getting caught up in the pipe. It is dangerous and can cause the brakes to jump into action and cause tyre locks while on long rides. Also the amount of pressure applied on the lever would cause the brakes to bite madly unnecessarily causing tyre locks.

Got my clutch adjusted to bike moves forward at half clutch release rather than at the very end like it was before. Now thick traffic doesnt hurt hand

Anyone with Blue NS. I want to get rim tapes done but confused about the color. BLUE or SILVER or WHITE

I'd say white. Check mine!

Btw nobody told me if it's alright to redline the bike while my odo still reads 900 km.

Looks HAWT n Sexy!!
Refrain from redlining till 2k kms atleast if you want a smooth engine in the long run.

600kms or first servicing - 4k RPM
1500kms or 2nd oil change - 6k RPM
1800kms - 8k RPM
2200kms or 3rd oil change - Go ahead and enjoy!

Always remember, you dint buy the bike to ripp it from the start. You bought it so that you can rip it afterwards. The afterward period starts post 2.2k

Remember, do not rip at at every opportunity thrown at you. You want to rev it, rev it gradually. You will enjoy the bike till it lasts! Count on my word.

Sorry if my post is not clear, which might have confused you.
The DTSI oil had been thin or had become thinner and hence you had a higher idle RPM
Your new 15w50 oil being new still maintains the viscosity and is thicker than the DTSi oil..hence lower RPM. Do not adjust Idle and see the Idle RPM after about 200 Kms of running...
Your surmise of thinner oil giving relatively higher RPM idle is Correct.
Like I said observe idle RPM after the next 200+ kms .

**matteyakhil** · 09-25-2012, 11:02 PM

hi guys am on 1400kms on odo using dtsi engine oil still thinking to switch to motol shall i go for semi syntethic or mineral oil also tell me where can i get them in hyd

"AFR Tuning" ? what is that mean can u tell me how it can be done.... ? my bike revving till 10,500 rpm .... how about the mileage.... 35 is that ok..... for the bike.......?
