Out of a gun.
Only if it's prepped and ready to shoot
Plenty of time spent on it Jim, but not much progress will do an update tomorrow when I get some pics.Thanks Mick. Any progress on yours since your road trip?
Can't. I made my V block fixture to fit Lycoming cranks and cams.... it won't close down enough to fit the inner journals. Here's how I did it.Jim, check your crank runout with the middle bearings on V-blocks...

Worst reading I got at any given point was about a half a thou...
Yeah, what we call stretch is actually wear on the pins and the holes. The links themselves don't actually stretch.Jim, just wonderin, someone once told me chains do not stretch, they wear. If you wear .002 off the pin that goes through the roller on a chain and that chain is 104 links long then the chain would be .208 inches longer, if .004 was worn off each pin the chain would be .416 inches longer, but if you measure the distance from center point to center point on the fixed pins the distance will be the same as a new chain, what do you think?
You mean like this...I wonder if there's room between the cylinders for a gear train that would eliminate the cam chain entirely?
Yup. Although I was thinking something a little less Rube Goldbergesque.... something, maybe a little more drop-in. But I think you'd have to replace the sprockets on the cam and crank with more conventional gears. A valid concept, perhaps, but a re-invention of the wheel. And we know they are round.... Better to pursue the tensioners on both sides idea, or better still....leave it alone.You mean like this...
JRP has a gear driven cam VFR750F Honda, all those gears make noticeable whirring noise.I seem to remember that Honda sold a performance bike some years ago that had a gear driven camshaft.
It was pretty complex and hard to work on from what I remember.
