guys i am looking forward to modify my 2004 model pulsar 150cc dtsfi. the bike is running in a good condition but feels its an old model considering the current pulsars.

planning to do some mods in looks and aslo in perfomances.

the mods in my mind will be like this
1. mono shocks ( which model will it be? how much it costs in blore market? )
2. bigger types - front & rear ( which size will be good and which brand ? )
3. changing rear end to new one ( will it be a direct fit & cost pls )
4. Adding a perfomance air filter ( will brand and the cost )
5. three pcs handle bar ( brand if anyone knows )
6. some perfomance mods in engine
7. free flow exaust -not very noisy ( pls suggest )
8. great paint job with less graphics
9. rear disc brakes (optional)

i would like to know how much it will cost for these above mentioned mods.
guys please help me out ( blore market will be close for to do the shoppings )
