Yes, a 7mm will work but must be done carefully and correctly. We will not do a 10mm crank on stock cylinders any more because they just suck compared to the cub motors from lack of transfer volume/flow. ie, you can't feed it very well. They also suffer big time from port timing being way out of the bubble for optimal performance. In our opinion, the 7mm is the largest sensible crank for the stock cylinders.
