If it is then I should go for a teeth change in the front because in this case I wouldnt have to change my chain which though has done 23k but the mech says it is fine.

Apart from this any other pro and con between changing the front sprocket or rear sprocket.
Sorry for late reply. I missed the thread.

You said, 1 teeth change in front sprocket = 3 teeth changes in the rear sprocket.
Yes, It is exactly equal, ONLY if your Final Drive (Rear Spr. Teeth/ Front Spr. Teeth) = 3.
For example, in a 14/42 teeth setup.

For all other Indian setups, it is "Approximately" 3, many times. For Example, in HH ZMA, it is 14/40, which comes out to be 2.85...

Yes, you can go for a Front sprocket change to see a good difference. 23,000 kms? Well, I hope you must have changed the "chain lock" once, when it was at about 10k-15k... If not changed, do so now.

Still, Changing front spr. also reduces the costs involved, and again, Chain can be adjusted at most times.

However, expert racers and other enthusiasts prefer changing Rear Sprocket, because it gives them more choice and freedom. In other words, it allows them to make "minute" changes...

As far as possible, You should choose a similar hardness material in all Chains and Sprockets. That's because, a Softer Sprocket will wear out itself quickly, while harder one will wear out/ damage the chain...

No, There are no other major Pro's and Con's, except the ones I mentioned above.

Try using the new P220 DTSi's Rear Sprocket. I'm 90% sure it works... It has a 36 teeth setup, which will help in cruising.
