Pearl green. Sharp! Can't wait to see more!

just went back thru this thread again! damn nice work. This a very cool project

Crankshaft is back from balancing. Marine Crankshaft inspected, magnafluxed, dynamic balanced the crank and micro polished the journals. $240.00 with one way shipping back home. I had wanted more exotic work, but Marine Crankshaft wasn't on board with going nuts. I can appreciate being told why and when I'm wrong, especially when it saves money. I have a windage tray/sloppage plate going in too.

here are some pics and the piston rod bobweight card.

They drilled the hell out of the weights. What % overbalance did they set it to?

I have no idea to be honest. sent them everything and told them what I was after and a wishlist including knife edging, polishing etc. Marine Crankshaft poo-pooed most of my ideas and only did what they though was needed. Probably saved me a good chunk of change too.

The crank still heavy. 20 lightening holes is like scraping a few cubes off of an iceberg.

If you add up all of the weights you get 1421 grams. Multiply that by 52% (a common balance factor for Guzzi engines) and you get 738.92 which is close to the 743.6 bob weight used. 52.3% gets you even closer - 743.18.

Engine is starting to go together. Here are pics of the Trankontinental clutch/flywheel assembly. The entire set up weighs 7.54 lbs.
If you look down into the motor, you can see the aluminum windage tray and the filter poking through it. Tom Hull machined an additional hole into the rear left side of the windage tray to ensure all of the oil drains back into the pan and doesn't pool on top when the bike is parked.

The engine is together. Squish is set at 44 thou, it may tighten up a tiny bit after it's gone through a few heat cycles and re-torqued. Piston and valve clearance is a none issue. I went with the mystery cam that came with the pile of parts I bought 10 years ago. It has slightly less lift than a P3 with a ton of duration. It should rev like a two stroke ( I'm hoping)

Nice job.

paint work almost done. looks a little dark in the pictures

Turin · « **Reply #106 on:** April 18, 2025, 01:46:33 AM »

Painted... number plates are being re-done. looked crappy. My painter added extra small flake with the big stuff. I'm waiting on the brake caliper brackets. and the seat pad. 90% there.

Ratso88 · « **Reply #107 on:** April 21, 2025, 08:45:28 AM »

Very nice!

Especially digging the metal flake

Really enjoying the pics & progress! Thanks for posting, Turin.

Turin · « **Reply #112 on:** May 23, 2025, 06:17:23 PM »

Here's a vid and pics. Almost done! I have to weigh this thing. It is incredibly light.

Turin · « **Reply #116 on:** May 23, 2025, 08:38:09 PM »

Thanks! it moved under it's won power for the first time today.
next steps
retorque the heads
adjust jetting
check the nuts and bolts
Shorten the clip-ons. I'm taking 2 inches off of each bar.

Then break in. I'm optimistically hoping for 80- 90 rear wheel ponies. It feels extremely light. I'm guessing 450 lbs. with a full tank.

Turin · « **Reply #117 on:** May 25, 2025, 12:38:05 AM »

flipped the tarrozzi clip-ons to bring them closer and shortened the bars on each side. The narrow tank makes the wide bars look wider than they are. The fork angle sits at 23.5 degrees. The leverage is needed. Installed lemans bar ends and one bar end mirror to keep things legal.

further tweaks to be done

Turin · « **Reply #118 on:** June 06, 2025, 12:22:15 AM »

Had my first test ride tonight. The bike feels very tall, even though it uses lemans 1000 forks and triples. Handling is alien and unguzzi like, part of that is the 23.5 degrees of rake and 2.34 inches of trail, and the rest may be due to the lack of weight. (I'm looking for a scale, will report back).
On the highway the motor is eerily smooth, almost like an 850. Not much engine braking to speak of. I won't be taking it past 6000 rpm for the first 1000 miles. After that, I'll give her the beans. It should make power to 9k. (I can hope). So far so good.

Great to hear about some road miles!
