Start with the Carb tuning, Air Filter and Free flow exhaust.

Also Contact Joel and other big Tuners for Racing Camshaft, Bolt on Kit, Racing Springs etc

Simple Trade your bike for a Higher Capacity bike, >P135

Do not try any rough stuff on your Platina, you will simply rotate things in circular motion and get irreversibly inserted vertical,

"I mean Screwed"

loved that one

No performance modifications possible for a Platina. Check the carburettor, replace spark plugs and air filter. You might notice some change in the mileage.

try tuning the carb n maybe changing the filter too might do the job, but you might not notice the power changes

mod does not mean screwing your bike.
I asked what are the possibilities ?
if its not possible thats ok.
mainly I am missing my 150cc and 225cc bikes here.

you probably need to tune the carb. You can do it yourself if you have some experience otherwise, get it done by an expert. Also change the oil and air filters and engine oil. You'll surely notice a difference in performance both in terms of power and FE.
Cheers!

Power & mileage are somewhat proportional. more power with good mileage? Try carb tuning. You can also try taller gearing.

Is free flow exhaust available for all bikes?If yes,then that!

can opt for an direct air filter ( K&N) dont go for cheap ones which are available @ rs. 500 they will screw your pistons with dirty air as i did in my bike.
a free flow silencer , i have seen a platina with free flow and it was roaring somewhat better ,

tune your carbs but dont overflow it with fuel as ehen its rich it gives crispy throttle responce but it just effects the spark plugs.

One more cheap trick is changing sporkets. dont know how that can affect your engine . experts may clear this point.

by dropping 1-2 teeths in rear sporket will increse your top end speed at the cost of pick up. and adding 1 teeth in front sporket will add you some more pick up but at the cost of top end speed.
issues may be speedo may not show your accurate speed , however it is 125cc but dont compare it with other 125cc s as its bore & stroke is lesser and with a small engine performance mods will not be that effective.

Dont mind for some negative points as i also suffer from performance mod incapability as i have Discover 100 ( 94.3 cc bike) .

now I am happy with its performance.its in stock condition ..
As I am a tourer it enough for me.
I have done even 900kms & 1200kms long rides with it in a day..
Just need to take some special care while long rides..
Have a plan to ride down to kolkata,waiting for a long weekend..
