The really perverted one amongst us
The XZ550 is a 70 degree V-twin. Both pistons go up and down nearly together, balanced with a balancer shaft and fire 290 degrees apart. The bike is wasted spark on each cylinder independently, and carbureted.
Is there any reason why I shouldn't rotate the cams 180 degrees on one cylinder. My thinking is it would still detonate relative to TDC but only 70 degrees apart instead of 290 degrees. Then the power strokes would be nearly together. It might not sound quite like a single but certainly different - more like a Harley perhaps.
Is that the same as re-phasing? Perhaps re-phase is not quite the word for it, as I think this usually refers to making the pistons go up and down out of sequence rather than all together.
Regardless of the term is this a good / bad idea? Is my thinking sound?
