          There could be a problem with the iginition coil or the alternator.
          This prolem is something to electricals of the bike.How old is the bike.Try to change the rectifier/alternator it should cost you Rs. 350-500 at the most and may solve your problem...

              First get some bigger jets both pilots and main before plonking in a K&N with stock jets and K&N your engine will get seized, its better you shift to stock filter in rainy season, there is no other way of making a K&N waterproof filter.

                To get a K&N installed its a hell of a job,left alone the bigger jets.
                You will first get rid of the entire air-filter box which also hold the battery.Then you need to fabricate a box to hold the battery.

                It is better u get a UNI filter which in rain,dusty or any condition is very effective....However,this is not solving your current problem....
