I asked about this a while ago and Captmoto posted a link to another thread showing of a few other people who had the problem and all got sloved under warrenty.

I too have had both my engine cases corrode badly around some areas + my wheels (espically the front) are corroding but i dont know if my dealer will be happy to change anything as they wouldnt even change a wheel bearing under warrenty even though i had only bought the bike about 6 months before hand!!!

+ the people who work in my local yammy dealer just arent interested in anything other than selling new people bikes. Once youve bought one thats it no more interest in you.
