I am really fedup with the petrol tank design of gixxer.In rain water is getting filled in the tank cap and now due to resting holes formed in that cap .They have provided a pipe for these water to drain out but even the pipe also got closed due to ageing .Now water is getting filled inside the tank.I dont know what is the logic in this design.only gixxer is having this problm.
Now i had spent 1000 rps for cleaning tank. and carborator and the holes are temperorly closed.
And have to do this in future also.Dont tell me uSe tank covers, it is not a part of the bike.
This is realy a big headache.
