looking good, probably have to play with the balance factor of the crank or counter balancer to find what feels best in your chassis dynamics along with crank balance factor/piston weight setup

What year crank is in that motor, I know some year cranks do not have the counterweight exactly 180 degrees from the rod pin.  I have a factory 86 crank that when it sits in it the cases it rolls the crank pin to about the 1:00 position where my other cranks both cr500 and 250r, the cranks will sit at the 12:00 position


The crank and cylinder were just some parts I had on the shelf. It's a 85 rotating assy. I bored it to 90mm. Cylinder is bone stock unported with a 39 pwk carb and the pipe is on CT made me for my first Cr500 conversion back in the late 80's.  I think right now I have two much weight in the balancer.  For now I will run it like it is and see what scatters first. I have about an hour on the bike now. So far no bolts have come loose. That's a first and when you ride it, it doesn't feel like you were holding onto a live 220 line.

Would be interesting how a crank with the counterweight 180degrees from the connecting rod  I would bet that 85 crank is like my 86 which is not exactly 180

the way you were kicking it does not at all look like you were kicking a cr500 engine

they kick reverse, and break your foot if you stomp them like that,

im talking about the first video

It was at a local race it runs good but had a clutch actuator prob and it was creeping.  Very slick set up though !

Without the decomp valve I can't kick it over.  It starts pretty easy if a big guy kicks it.

Decomp valves are a life saver i hear, im a big guy and i wont kick my 86 without at least thick soled work boots and even then i have to roll it over to tdc then kick it like im trying to break it. And by roll it over i mean stand on it till the compression seeps the piston over
i cannot imagine the beast of a man that could start it on the side of a muddy hill after a hangup in a race

i forgot you done a bunch of work inside the cases with the balancer and what not and there may be more going on there than meets the eye

Fixed the acuator arm doesn't creep forward anymore and seems to be holding up nice now.
