[Resolved]  Yamaha Fz 16 — Alloy wheel and Handle bar Colour and Oil problem

i m Gaurav Choudhari from Amravati, Maharashtra. I purchased Yamaha FZ16 on dated 24/10/2008 From Tajshri Motors Nandwan, Nagpur. But the day i drove it to my home its front disk is making some kind of noise. And 2-3 days after 1st servicing which only include washing and Engine oil change i found that the black color of front alloy wheel is removed at the corners of wheel and also handle bar color is vanishing. now the alloy is looking like, it is painted from some local painter.and when i complaint this issue to the service provider they say me that " Ab yeh To gaddi hain, 2-4 mahine main toh color niklega hi. isme main kuch nahi kar sakta. " Means its a vehicle there is no guarantee of color.i cant do any thing in this matter. and also there is leakage of oil from Engine. But the shop owner says u must applied some chemical to it or some sort of acid. they are not interested in solving my problem rather they are telling me that its ur mistake. I m Engineer by profession n i know that what care should be taken while maintaining the Bike.Now can anybudy help me out of this matter ?? what should i do??
