Vacuum leak ??(whistling noise)problems after valve adjustment by factory mechanics. Ever since I had a Yamaha dealer adjust my valves and put on 2 new tires, I get a whistling noise(driving me nuts) at around 20 mph to around 40 mph.They replaced front brakes and said all was well, but the problem still exists.The noise also sounds like it could be something scraping on a brake disk or drum, that's why they changed the front brakes .

Hi, Wallace if you take your bike to a dealer for a specific issue that costs outrageous amounts of money only to have the same problem 2 days later your situation is not unique unfortunately and it is a double-edged sword. First, you suffer the emotional stress and frustration of spending all your hard earned "Drachma" and your bike does not get fixed. Second, comes the realization that not only are the technicians incompetent but also the service manager for not doing anything about it, this isn't rocket science, it's a glorified lawn mower engine with extra cylinders and carburetors sometimes. You need to put an end to all the double talk, dancing around the issue, and a "we don't care attitude", but how you ask, very simple you exercise the "nuclear option" go back to the dealer and ask to speak to the owner or general manager if the owner is not there, then with a straight face and polite voice you ask him/her if they can provide you with the name and contact phone number of the person at your brand motorcycle headquarters in your country that can recommend a repair facility that will fix your bike because your local dealer either can not or will not. I guarantee you that is all the grease you need to get someone to light a fire under the proper persons rear end to resolve your issue "toot sweet"
