Keith is the inspiration for my ST 90 project. Ken Lambert has also contributed and the little ST 51 was just an experiment to see if I even wanted to proceed with the 90 project. The hardest part of that has easily been the hardened pin on the crankshaft. I've had so much fun with the little 51 that I'm getting anxious to get the 90 going. The Saito on gasoline is cool but I just love that two stroke howl.

Hope all is well out in Arizona and Happy Flying.
