Ray, Gents

After I did receive the data from Ray of the ST56 I do have make two pictures to look at and to show you how I look to the differences:
1 the ball bearers VECO 45 and ST 56
2 the K & B 45 Torpedo "Super Sucker"

It is possible that the K & B 45 also has a better internal breathing because of the better compression ratio of the crankcase.

When the power is enough of the K & B 45, the less weight, more stabile fuel/air ratio and the less fuelconsumption of the K & B could be the biggest profits.
Because of the light weight of the Taurus I think the K & B 45 was the best for the idea of Ed ,as constant speed as possible.

Still waiting for comment on my post 229
