A buddy of mine just called me up on his way to work and while riding his bike it started shaking severely and he exited and pulled over to check. He noticed some smoke and unscrewed his oil cap and smoke was coming out. He tried starting it again and it would not start. His bike is new, 2006 GS500. He took it in for the 600 mile service and they told him not to bring it back until 4000mi. He has 3400 miles on it now and this happens. In reading I've heard that the GS500 is notorious for burning oil but this bad? Well I'm on my way to pick him up and the bike but I thought I would throw this out to see if anybody else knows of or has had this same problem. The dealership and service guys are going to get a mouthfull today.
