Ok guys and gals need help

About 4 weeks ago I got caught in a downpour and was caught in it for about an hour :'(

Ever since my SV650 (forgot to mention I was riding it at the time :) has developed starting problems, it's ok when it's going but it seems to take numerouse attempts.

I've checked the plugs and it's been to the Bridewells garage at Etcelhampton to have the chain and sprockets renewed, they thought it could be something to do with the cut off switch, when it's played about with the bike starts. They've tried changing the unit but it was still the same :'(

Any ideas ?

:-* ;D
