Turns out I was missing a few parts that will certainly make my life tuning, much easier...
Throttle cable adjusters were missing (PO had duct tape as a substitute), as were sleeves unique to the R69s that go into the heads, through the carb flange isolator gasket doohickeys, as well as washers that go on top of the floats...

Just for giggles I ordered new air bleed screws and lock nuts, too.

While waiting for the box of goodies to arrive, I thought I would diagnose whether or not differential timing was an issue since one cylinder was running hotter than the other. Short answer is that timing is so close between cylinders I couldn't measure the difference.

I think I just have carb issues that will be oh so much easier to sort out with a few simple parts...

First ride coming soon!

After the first 20 miles on my fresh R69s rebuild I am sure of 2 things. First, this bike is awesome. Having rebuilt this without ever having ridden a /2, I was giddy with excitement having finally getting her out of the shop under her own power. Problem is, the weak link in the whole mix was the machine work on the cylinders. She smokes. Way too much to just be rings not seated yet. White smoke, increasing under acceleration. Heads were done by Memphis Motor Werks and I am sure perfect. 20 miles was enough to foul the plugs with oil. Bike is resting in the safe haven of a local Triumph shop and coming home later today. I am disappointed; but, I am sure this is just one more lesson. The process has taught me much so far. Time to learn how to measure cylinder / piston tolerances.

More as the story unfolds...

When I was rebuilding my R50/2, most folks recommended I send my cylinders and new pistons/rings out to the folks at Bore Tech. They know they're business, and the newly honed and painted cylinders came back perfect match to the new pistons/rings. The price for the work was reasonable, too.

Thanks,
I am getting the same advice from several sources, and depending on what I find when the cylinders come off, they may be on their way to Bore-Tech soon. I am anxious to get the bike home and start investigating... The Triumph guys have speculated perhaps not enough assembly lube resulting in galling at start-up.

We'll see.

carb leaking

seems to me if gas is leaking from the air screw the float may be bad or sticking and flooding the cylinder. remove float and shake, if sloshy sounding replace with a known good one.

WOW! How did I miss this thread?

Beautiful job. Very very nice.

Oh, and don't forget to put the timing plug back in there.

The older I get the better those look, and that's a fine example.
