Thanks guys. I don't really know this engine that well, but I do study the manual and there's some much info on-line

Cormanus, hopefully I've done a good enough job so the paint & other details hold up after putting some miles on it.

Couple of updates

Had done some of the polishing previously, broke out the wheels & rouge. Got my dust mask, goggles and gloves. Man, I really don't like doing this, but it does give my wife a good chuckle... . She claims I look like a raccoon or alien when I'm done.

Okay, onto the pics. The parts look way shinier than they are.


Starter stuff. Needed to be cleaned, painted & tested.

Engine updates

Won't be using the cable drive for the tachometer. Found a piece of scrap aluminum (scratched up, but will work). Machined it so it would fit in the bore of the tach housing.
More on this later.


Pistons being installed


Cylinder, timing chain, rollers & guide


Sometimes I wished I had three hands.
Timing chain was to kept up during assembly. Trick is to devise a way that is easy to "unhook" to keep adding parts.
Used a bungee cord, connected to the garage door rail, then a piece of wire to go between the cord and the chain.


Cylinder head & camshaft sprocket


The tach drive "plug" in place. There's a seal in the bore, which explains why the piece looked strange. I'll replace the screw with an Allen head later.


Pic of the camshaft (red stuff is assembly lube).
Valves adjusted, .002" Intake, .004" Exhaust


This is as far as I'll go until it's in the frame. My brother & his son are coming over for some welding. I'll see if I can bribe them.

Fantastic, Ray. I'm full of admiration.

That bike is going to be awesome when you get it finished. Thanks for the updates.

+1 you have quite the mechanical ability. I'm so jealous.

Excellent work! Very impressive

Beautiful job! Eager to see the finished bike.

Razor, A friend uses one of those vibrating vats full of walnut shells to clean all his odd shaped small parts. Pretty inexpensive at Harbor Freight. That might be a good replacement for the buffing you hate.

Thanks for your interest and comments.

Don't have a vibratory tumbler, but I know someone who does. Might have to try it out. Funny thing about walnut shells; tried them a while back in the cabinet, and didn't get the results I was looking for. Maybe the tumbler is the way to go. Thanks for the tip

Kinda neat what a bag of Fritos and drinks can do...
Brother helped me put the engine in the frame

Prep'd frame beforehand




Installed the starter


Much more to do. Approaching a couple of "milestones". Still need to fab a push rod for the clutch slave, and then there's the "body work & paint".

Thanks for your interest. I'll try to be prompt with updates.

Holy Master Fab Craftsman Batman!! This whole build blows me away. More photos please!!!
