A flickery problem

Hi

I just noticed something new

I was stopped at some traffic lights I had put my indicators on to turn and I sat there idling then I look down and the indicator was off.. so I put it on again and watched it... and it like came on and off like normal then after about 2 or 3 flashes it started flashing slower.. then eventually it went off and didnt come back on.. so I put it on again... but this time kept the revs up alittle and there was no problem

I thought it might be battery but I have no problems starting the bike

I have been riding abit more then usual in the rain.. (stupid auckland winter weather) could the rain have caused this problem?

thanks

 

Ill try adjusting the idle.. strange thing is... I just noticed it doing it lately like in the last 2 or 3 weeks not often maybe once a week
