I had the 350 version which led to buying a big 750 with chambers and cafe-racer fairing all blacked out, it was a fun ride.
However I used to frequently smoke cylinders on that until I got rid of the oil injection and just ran premix.
It got to the point on all of them that I would only fix the affected cylinder, the 350 version had 3 different bore sizes, but still wheelied like no other bike I ever had LOL
