Just thought I'd share this. Just got this bike on the road for a good friend who has been working on it for the last couple of years. The engine was an "unknown" as it was supposedly done by Hieden Tuning about 20 years ago and never run. Well, holy shit, DOES IT EVER RUN! I have worked on and owned Yamaha's famous 650 twins for the past 33 years or so and have never ridden one with this much raw power. A gorgeous machine and what a blast to ride!
