@i.ahmed smaller tweaks like adjusting carb, making powerful ignition, putting better plug using better fuel (in combo with STPs) will do some improvment in accelration but given a heavy bulky bike it will not be able to tip lighter vehicles.
If you downsize the rear rim to 17' will make a huge gallop in intial acelration as engine will be rotating less mass (tested better performance on omer85 bike) above all tweaks including the smaller rim were applied and bike started to accelerate head to head with CG in smaller strips.
but If you really want to make it a class apart then for the given body weight at least a 200cc engine does the justice and that is not recomended given that your bike is brand new already, so its like ruining all the money.
