They vary mostly in the wear speed, propensity to fracture or fool. Other than that, a spark is a spark.

Hi Bill...still working on it.

I've replaced the 6 Sealed Bearings. Since putting the Trans in place I'm finding other problems during re-assembly of the bike. Needed new 52x2mm O-Rings for the Throttle Bodies, a new Snap-Ring for the Drive-shaft Coupling to Trans Output Shaft...I might find more little problems. It has 70k miles now. Hopefully I get it going sometime next month.

Yes a "spark is a spark" but Flamefront Propagation is everything to a large bore engine. This is why Twin-Spark is so good.

A very good book to read about combustion is:
C. F. Taylor, The Internal-Combustion Engine in Theory and Practice, The M.I.T.
Press, 1985

The orings in the tbodies were leaking eh... That would explain the the rough idle and clanking tranny. :)

The extra power obviously has to do with the pyramidical shape,,,, SmileWavy
