No, I don't think that will fit. Even sprockets with similar fitments, like 4 holes, might not fit each other!

Fitment is just a measurement. For example, P200, Karizma & 220 have bigger chain and sprockets, you can't fit them to Pulsar 150 ... despite same fitment.

I'm sorry, The list has only K4-100, Challenger and King...

1. Well, your new UG4 has a final reduction setup of 14/39 ... But, I'm unsure about which chain/sprocket "size" it is ... One common size is P220/ 200/ ZMA size ... and the other is a smaller size of P150 UG3 / P180 UG3/ etc...

2. So basically, you want to overgear it? That means a bigger front sprocket, or a smaller rear sprocket is what you need now.

If it is Normal same Size, Pulsar 180 UG3's front sprocket (15 teeth) will do the job.
If it if Larger Size, then you can use Rear Sprocket (37 teeth) of Pulsar 220 (old DTS-Fi) ...

In either case, you shouldn't change the chain, as its 1-2 links change and chain can be adjusted to this much change,

3. Yes, any change to overall gearing affects mileage. In this case, you'll get more mileage provided the same riding style as before.

In this matter, keep looking here, as I might provide updates on which sprocket fits it.

Sprocket for ZMA

HI!!

I have a Zma which is slightly modded, like K&N, free flow exhaust, Iridium plugs, bigger jet.

I want to increase the top speed.

I guess a 2 tooth decrease in the rear sprocket should be enough.
Please suggest. Also I read in this post that P200 has a rear 38 sprocket and Zma has 40 and they both are direct fit. SO should I go for P200 Rear sprocket??

What can be the other options and which will be best??

The gearing would become very tall, as reducing the same you would then need to OVER-REVV each gear,and the initial would suffer a lot in Double,forget it!

Thanks man!! BUt I do feel that the power produced is actually not being put on the road. How about a teeth change then in the rear sprocket??

Put some more Input,and clarify the things more,it would help in getting a clear view..

My bike used to touch 140. Now after the iridiums it is not. The bike needs to be tuned that can be one reason but I have felt that it runs out of breath at 135. The initial pick is awesome as many a times at loose surfaces i have experienced a wheelspin.
My driving style is also like driving at higher rpms. I want to convert these rpms in kmph which are not getting converted. Also because of my driving style in search of speed a find the engine to be revved higher for long durations.

I can compromise a bit on intial as I think my bike has enough initial grunt that even after 1,2 teech change in the rear sprocket it should be good enough in pick up terms and the top speed would increase because of sprocket change.

Its just that I have not done it, so I was asking that would a P200 rear spocket good for my bike??

yea P200 has 39T in rear

Why don't you try for P220's rear one which has a 38T
or if you need more then the latest p220 DTS-i has 36T.
Mind you, top end will increase, on the other hand the initial acceleration will decrease.

May be the tuning of the bike is not upto the mark. Can this be possible from your side??

Err....P200 has a 38T and P220 has a 37T rear sprockets.

Are you sure about the new P220 having a 36T?? Coz the mech the PBK here was saying the sprockets have not been changed!

For all members:-->

P220 DTSi UG2 --> 36 teeth

P220 DTS Fi Old :--> 37 teeth

P200 Old :--> 38 teeth

Karizma :--> 40 teeth

P180 New :--> 39 teeth, Chain pitch I think maybe .520. Not sure though.

---
@ Rachitkdogra: See, 3 teeth changed on rear sprocket does NOT severely affect the gearing, even on a STOCK bike. I have done that, Trust me!
But, since your bike is modified, I say you should go for 37 teeth mentioned above...

So, go ahead and fit it in your bike. I know its ZMA and has a longer 5th, but its better performing than stock.

??? Were there 2 versions of the Fi launched? Please clarify. And identify your sources.

The P220 has always had 37T. The P200 has always had 38T.

Are you sure about the P220 Dts-i having a 36T rear??

OT: Dude, did you loose some teeth recently? Just asked coz your cheeks appear kindda sunken.

My bad..

P200 38T
P220 DTSFI 37T

P220 DTSI 36T(Aparajit and I went to PBK in delhi and observed the sprockets, it was written 36T )

Fantastic, this is real good news!

@praful: it's the time to change my sprockets of P200.

What you suggest.
A 37T old one or 36T , newer one??

Any pros and cons and will 36T make the gears taller?

Rohit,Reducing the teeth's by two is always good for the chain and its revolutionary nature,however it also needs to be simultaneously compensated by the ration of the front sprocket as it is the one that runs along with it..
One sprocket reduction would do much harm and to the new chain set and the chain roller's would get cut or damaged soon..

I wud advise a complete change of the Chain Set along with front sprocket,rear and the chain.

Or do not do anything like what LP did with his Discover, he had changed only the rear to 42,it created a problem.
and the front 16-39 as rear, Again a problem..

Pls do not perform any such kind of stunts with BIke like he did..
You know him.. Don't You..

Now every thing is running fine with his De-sprockted 125CC, Have you ridden it..

i think when we were painting your rear rim
