I had my dealer do my 600 mile service, paid the $200.00 or so and have regretted not doing it myself. Shifting felt a bit funny leaving the dealer, I thought maybe I was just feeling it different due to having new boots on for the first ride. As I went a few more miles shifting from 2-3 and 3-4 became difficult and sometimes required 2 or 3 tugs on the shifter. I got the bike home and checked it over, no leaks or any other obvious things wrong. The next morning when I shifted it into first the bike stalled. The clutch refused to dis-engage with cold oil in the trans. Left it parked in the garage and took the truck. That afternoon I looked a bit closer and realized the oil in the engine smelled more like gear oil than motor oil. Draining it verified that the tech put the wrong oil in the engine. 75w gear oil in a crankcase and transmission is not good! In 60 miles of driving the gear oil was in bad shape. Fresh oil and filter and my shifting is back close to normal again. I am waiting for a call back from the service manager. Unless there is a warrenty issue I doubt Yamaha techs will ever touch my bike again. :angry:
