Thanks for the info
That was really quick reply

Edit: One more question, Is it possible to fit P200 chain/sprocket in ZMA?

With what purpose do you want to install a chain/sprocket with lower tooth..?

If your purpose is to increase the top end of the bike....then you can do that in the existing chain only...

I'm not 100% sure about this, I think Joel or someone who's done tinkering around with a ZMA will be able to answer this. But I think its a straight fit.

But we warned, the 40T sprocket is just right for this bike, anything smaller will make this loose huge amounts of torque...you will be loosing more than gaining anything.

if you want to increase the top end of the bike cut down one or two tooths of the rear sprocket.................
that'll affect the acceleration but will give you a higher top speed........

**Akshay.** · 11-09-2008, 09:13 AM

Reducing teeth in rear sprocket wont give any top speed gains since 5 th gear of zma is already tall and the bike doesnot have much torque to rev beyond 8K in 5th gear.Smaller rear sprocket will give a relaxed crusing speed but you may lose on top end.
Dont try sprocketing unless you have some good engine mods.

Today changed the engine oil to Castrol Power 1 Racing. The 10w40 fully synthetic blend from Castrol. Immediate feel is smoother gear shifts, lets see how it fairs after a fw kms. Got the can from BikeWorld (Name has changed i guess

) Rs. 725.

Basic reason is I wanted to go for O-ring type chain to avoid Chain covers.
Is there any other chain/sprocket available O-ring type that I can fin on my ZMA??

Then simply ditch the chain cover. With out the cover the chain may like wear out only 3-4k kms earlier. Anyway ZMA chain sprocket set is now like 700 bux only. It may not be good idea to alter the sprockets for this purpose at least.

Ya we know that the 5th gear in the ZMA is tall enough but.....reducing the tooth in the rear sprocket....it wud helping in more of a cruising speed and to some extent it would also increase the top end merely due to the fact that not much power would be required to pull the wheel bcoz of the short sprocket so it can easily cruise at high rpms and get a good top end...

well, no offences meant in the post....just what i know i shared....and hove some experience as it has already been done on one of myu frnds bike...

Well if you don't want the chain cover then just remove it why are you altering the chain size... !!

Not sure if the chain length is enough, but you can run the O-Ring chain over the zma sprockets. the Pitch is compatible, but I'm not really sure if its long enough.

+1 to what Praveen said, and if you take good care of the chain like cleaning/lubing every 300kms then it surely will last you long enough.

The stock ZMA is not making enough torque to take the downsize of 2 teeth, you will just not enough power to pull the bike as it used to originally pull...moreover the speed that you think might achieve will also not be possible due to sluggishness.....

Thanks guys for the reply.

I have already removed the chain cover. I know the O-ring chain good for open type that is why I thought of going for that. I am happy to go with HH OEM products as always.

**Jonak** · 11-13-2008, 03:54 AM

Can any1 tell me what should be the ideal rpm when the engine is idle in cold condition??? I own a ZMA R, its 2 months old and done only 900 km...
The user's manual says it should be 1400+/-100 (ie, between 1300-1500) but the HH service center mechanic said i should keep it at 1100 rpm.... Im confused...plzzz help me out......
