[Resolved]  Honda Unicorn — problem in riding bike while raining

hi,
my unicorn is a 2007 model, from the very first rainy day itself i have problem riding my bike.
It stops running when thier is either rain or water logging in the roads. I have complained several times to
the authorities (marikar honda Trivandrum).
they have not yet figured out whats the real problem is, pls some one find an answer for this problem.
