Went out last weekend and my "98" ZR 600 efi wouldn't power off the line like it should.Its a fuel problem!! New belt and plugs ,even changed plugs again and the same response.At5 grand going down the trail you hit it and it will pull the skis off the ground,but at a dead stop it like bogs down.Any info would be real helpful.Of by the way the other thing I did was took off the gastank and seat but the fuel lines are hooked up the right way.
