Vapor lock man, happens commonly. Just open and close the lid and it should be normal again. Pretty common issue, not only on P200NS but on all the petrol bikes. Also check the vent holes on the lid, they may be clogged.

Hmm, if its vapour lock, wouldn't the stuttering still be there even if I switch to reserve. The stuttering stops when I switch to reserve.

Thanks a ton man, but when you have to brake from 80kmph to 12-14 kmph then you cant accelerate at 4th right?? you have to atleast come to 2nd gear to do that.

So if you see busy traffic ahead and anticipate joywalkers and other retarded cagers, downshift to 4th. Be vigilant on the road and always expect the unexpected, that's the only way to ride safely in India.

My understanding is the reserve petcock intake is submerged in petrol all the times, as it is shorter, so switching to reserve eliminates the problem. That's the reason this does not occur when the tank is full, as the main petcock intake has a lot of fuel over it building up more pressure. That's why the bike acts the same way when you are running out of fuel and hitting the reserve.
Next time it happens, try opening the lid as I suggested, this will prove if it's vapor lock or any other problem.

first one- i am planning a trip to Kerala on 28th of dec, and trip is about 1500-1600 kms. I have only done frst service of my bike at 550kms. Should i get it services and change oil to Motul 5100 or should i return from trip and then go for the servicing and oil change??? as of now my bike is running good with 42-45 kmpl with 70-80kmph on city roads.

second question- How long can i stretch my NS without stopping on a highway trip?? I mean its a liquid cooled so how far can i go without taking a stop?? i heard on p150 one should not go beyond 100km in a single stretch. So at what interval should i keep stopping to keep my engine safe n sound?? (Sound plays major role here, i dont want my undwerbelly baby to sound rude to me )

And now the gear lever problm, when i downshift fast, it gets struck or sumtyms it gets totally free and moves like nothing is attached to it. But when i press clutch and start downshifting slowly it works fine. But problem is that in case of hard braking i dont have enough time to downshift slowly and got into scenarios where i was standing in middle of the road with speeding traffic on the highway cause i had to slow down because a car took urgent brake and as cant downshift so had to stand still and then downshift as i was stuck in 5th gear and my speed was too low to pickup frm there. But SVC people say its meant to be downshifted this way only and my gearbox is perfectly fine. Dunno what to do, i am in chennai and dont even know their language.

Still if that doesn't help then you may need to get the petrolT replaced as the main petrol intake area may be clogged with something whereas the reserve intake may be in good condition.

Try blip downshifting to have more precise downshifts. There are N number of videos on youtube which teach you exactly how to. Even Ducatis have this downshift problem so don't worry about it blip downshifting is the way to go.

Ah! blipping the throttle reminds me of my early riding days on the RX135, NS does seem to have some 2-stroke characteristics after all.

Almost. Tall gearing takes some of that away. It's so smooth and composed in building up revs. Doesn't go noisy and hooliganistic like the duke 200.

Hi All,

I've clocked 510km on my 200NS,

First 200km or so I did gearshifts on or around 3k rpm and kept the bike below 55km/h and then gradually increased gearshifts to 4-5k rpm and not exceeded 75 km/h till now.

Things I'd like to have done is change oil at 250 odd km's - now that the bike is due for 1st service can I switch to Motul 5100 or better stick with Bajaj DTSi?

Also, I'd like to change oil again at around 800-850 kms - again Motul 5100 or Bajaj DTSi

Pardon my ignorance if this has been discussed already - awaiting replies !


Cheers
