Fellow speed freaks, help me build a pair of speed Bees.

Also, you could get with Micro and check out his Killer bee I think he did all the mods apart from drilling the venturi. I could be wrong about that though.

Very good info in the bottom 2 documents there.

I like to polish the crankshaft. I don't know if it actually helps anything but it makes me feel good. I start out putting some three in one or light machine oil on some 400 wet dry sand paper and put the crank shaft in and use a clamp to lightly clamp the shaft in the paper so there is even friction and surface contact on the entire crank shaft and begin spinning the crank shaft. ONLY spin in one direction. Do this for about four minutes then switch to 800 grit then 1000 grit. You are only trying to remove any burs or surface imperfections. Make sure to thoroughly clean the crank shaft before reinstalling it. Put a drive plate and prop on it and it should spin freely with a dry fit.

Good luck and let us know if you think it actually helps or just sounds cool when you talk about polishing your crank (Sorry, I had to say it.)

Thanks Bob, and everyone else for the replies.
I've read all the papers and know all the parts. The polishing is one detail I was wondering about. I know the KB cranks are softer steel than standard Bee cranks(contrary to my best guess), so I'll be careful not to over-do it. This will be my Spring project, so right now I'm just formulating a plan and making a list.

I'll address piston fit when I get there.

Muchas gracias,
Rusty
