So I did a Putty Run today with two other Netriders. One of the best bits is a section of road creatively called "The Ten Mile" - ten miles of twisty bits. It was so good, we turned around and went back so we got two more times through. At some stage, I noticed my speedo wasn't working and my engine light came on. I initially though the engine light could be on as the engine may have been a bit hot - air cooled bike working through the twisties maybe? I thought the speedo cable had probably come loose at the wheel and a quick look showed it had. No little cable bit on the end, so no more speedo. But the engine light remained on. I still thought temperature, but it didn't feel hot. After the lunch break it was on straight away. Maybe oil - but it wasn't leaking and hadn't been low before we left. The engine sounded like it was running normally, too. So maybe it was linked to the speedo (both happened at the same time) but why? The speedo on the V-Star is mechanical, no fancy-schmancy electronics. Anway, it turns out it is directly linked. Yamaha isn't too so-fist-er-cart-ed with the check engine light. It doesn't measure temperature, or oil levels. It measures whether the position of your throttle is ok for your speed. If not, the light comes on. Quite relieved really, only a $33 fix to replace the cable.
