No buddy, DONT do that. There is a reason that FS is not recommended during the break-in. It will glaze the cylinder walls, and your bike will never break-in properly.
Going for SS oil is OK, but FS is seriously not Recommended.

NS - 18.3 Nm @ 8000 rpm
220f - 19.12 @ 7000 rpm
ZMR- 18.35 N m @ 6000 rpm

Not too much of a diff there.. so dint mention it !

Isn't the difference in 6000 and 8000 rpm significant?? I was impressed actually when I saw NS gives that kind of torque @8000.

yeah and NS' power is also at the top end so it is way better than those two at higher rpms

Damn this torque and bhp thing. i could never understand them. For a poor man like me it like - jitna zyada hai utna hi accha hai.

So what how much power (bhp) does each of these bike deliver at those RPMs i think it is here that makes all the difference.

If possible somebody please do a drag race with Karizma and 220 and post it here to clear the doubts of all who are still skeptical .

Two things are to be looked at: peak torque value and how wide the torque band is. There are two kinds. One is which gives high torque for narrow rpm band (graph of torque vs rpm would be like a mountain peak). The other would be the one which gives moderate torque but over a wider band of rpm (graph of torque vs rpm would be like a plateau in this case)

Same for power, how much peak power it gives and how wide is power band. Power curve is little complicated as it is product of torque and rpm.

To say anything about a bike you need to see both the power curve as well as torque curve. This is because power is function of torque and rpm.

By side effect I meant what could happen at low Idle RPM setting. And yes there is definitely something wrong with it!




1.8k is a little too much as per the specification in the manual. But then every bike has its own behavior! I'd say, set it as per your requirement!




I have this problem too. There is a lag in the engine response. The main problem here is that you feel like your bike is about to stall when you try to escape a corner by accelerating hard. IMO, this is a confidence killer.




Even I did the same. I have a Karizma and a Pulsar 200NS now. It was a windy day, on a drag race between both my bikes. my Karizma took initial lead. But then I was able to overtake it and go off with my P200NS. I kept the lead till 120km/hr and then the Karizma just went off as its got a fairing and so aerodynamic. The top speed of my pulsar touched was 125 and the Karizma 138. And yes My Karizma has a K&N air filter tuned for max performance.





I have written one a couple of posts back. As of now that is the only solution for random increase in Idling. As per the delay in the throttle response even I am speechless. To get over this, I tried reducing the accelerator free play. It is very minimal now but still there.

Putting the CF on radiator shrouds was Rohan's idea!

In this pictures I have not applied any polish anywhere, just normal washing. Infact in the morning Rohan saw my bike in pathetic condition.
Thanks for the idea Rohan, for the shrouds!

There's a huge difference in Power to weight ratio of ZMR/Karizma. Also even with more torque, NS beats 220/ZMR/Karizma hands down. The acceleration of NS is superb.

arey i was talking simply about torque...that too low end...not outright performance... Karizma is known for the pulling power and the torque even at the leanest possible AFR setting..... Other than that the ns can beat the hell out a karizma anyday
@all: the problems faced in the bike are odd and funny... Hope bajaj rectifies them soon and offer the changes to existing owners free of cost...

Thanks for the replays guys

yes, the idle speed is low. At the time of cold-start, engine goes off if I leave the throttle in the initial stage, but later its works normally


is it !!!
there is no trouble apart from
1) At the time of cold-start, engine goes off if I leave the throttle in the initial stage, but later its works normally
2) it start to move-on on 1st gear only when it reaches the 2.7K to 3K

and one BIG advantage of my bike condition is, my friends could not able to ride it as engine goes off

And coming back to lean mixture: I heard that, lean mixture cause engine heat problem and hence it lead to damage in the piston rings and so on... (correct me if I am wrong). so as i said earlier, my RPM is set to 1000 (by default from day 1), and when i give choke it raises to 3000.
NOW the question is: do i need to change the CO% screw or idle screw? (anyways am not going to touch any of those screws. but if i know something about it, i can say SVC guy to do as i needed)

Damn this torque and bhp thing. i could never understand them. For a poor man like me it like - jitna zyada hai utna hi accha hai.
