Start time!

Back from the first ride in the rain (this is the Pacific Northwet).  Rain cleared later and did a 65 mile ride. Needs some fettling, but it's getting there.

Thanks guys.  Yes the engine is quieter than it was.  Today solved the idle/progression mixture problem by making (ahem!) a new carb needle.  Idles sweetly now. 

I'd over tightened the suspension so it was a rough ride.  It's getting there.

Today has been too rainy for me...

OK - big problem.  It smokes way more than it should.  Smoke so bad I pulled the top end off to see if I'd broken a ring or failed to seat a pin clip. 

Someone scarred the ring lands when drilling oil holes in the ring grooves.  For each hole in the skirt there is shallow trough feeding oil past the scraper ring.  Any ideas on how to fix this???

Doh! Short of a replacement piston, maybe machine the groove wider and fit a wider ring? Just "spitballing".

That's what I was thinking, but who cuts ring grooves any more?

My two bits is a new piston and rings.

I would be reluctant to try wider rings, getting the gap / clearance / gas pressure correct to seal the rings is close to rocket science. My Morini 500 had custom rings fit from some kind of fork lift engine, previous owner meant well but the machining of the piston grooves / bigger rings resulted in 80 ~ 85 psi per cylinder. The rings fit the cylinder but the gap / clearance etc was all wrong. I had to get LA Sleeve to resleeve the cylinders and fit stock pistons and rings.
I read an article in Classic Bike Guide by Richard Rosenthal on the subject and it left me of the opinion that stock designs of pistons and rings is critical to good running.

Thanks Canuck!  The cylinder has already been sleeved and it is a standard bore running a new Falcone 4-ring piston. Problem is someone carelessly modified the piston.

I've polished the ring lands and it smokes much less - but still more than normal.  About like a 2-stroke :evil: 
If it won't bed in I'll be buying another piston...

Now to get an exhaust system and some decals.

Nice fix and clever use of a template to hold the sand paper!

That's a great build Earl. Who did you get to do the painting? Was it someone in the Coleville area?

Thanks JD.  (BTW my name's Shawn, Earl is my father)
Painting was done by a guy in Whatcom County that does it in his spare time.  He used to have a body and paint shop, but now mostly paints bike projects.  Pinstriping was done by a guy in the Seattle area - Dunn autographics.  https://www.dunnautographics.com/  Both did a great job.

Thanks Shawn, sorry about the name mix-up. Whatcom is just south of me. When I get a little more ready for painting an old bike I have I will maybe get hold of you and get the painters' name. No pin striping involved.

Perfect - I'm down in Bellingham.  Hope to meet you some time soon.  His name is Kevin and has an old airhead and some other funky things - mostly Japanese.  He's finishing up a Honda 305 Dream for himself now.

Finally got the correct decals (https://classictransfers.co.uk/) and put on a new exhaust so took some glamour shots.  Now I'm afraid to ride it!   :rolleyes:

This is why someone like you needs to have this bike rather than someone like me who would have had no idea how to even start, much less finish, such a project.

Thanks guys.  It's not perfect, and it still has some hiccups but getting there.  I couldn't have done it without the help of people on here - esp. Patrick, Charlie, Canuck and encouragement from all of you.  There are many helpful people on the Guzzi Single Cyl. forum too https://groups.google.com/forum/?hl=en#!forum/guzzi-singles

This is why someone like you needs to have this bike...

I like fixing things but it was just about beyond me!  I have learned a LOT!

A guy in our vintage club is a professional photographer-artist and asked to take some pictures of the GTV.




He uses a digital SLR to set up composition and lighting for the real shots with his large format B&W film camera.  So here's one of his "preliminary low res" test shots.  Wow!




He's got a great collection of motorcycle engine shots and lots more on his website: https://www.johnolsenphoto.com/

OK - crazy thing.  At some time in the distant past, my GTV had the original 1937 engine pulled out and replaced with a 1948 engine.  Probably in North Africa by the wind abraded silica sand jammed into the engine and suspension.  The engines are the same except the '37 has a 2 exhaust port cylinder head.  The only remnant of the original engine is flywheel #34542.  (why didn't that get replaced???)   The '48 engine number is 77314 - a difference of almost 43,000.   

Does the original engine still exist??? 

An internet friend was rebuilding a Falcone that had a crankcase with a broken lug.  It was an old GTV crankcase.  He bought a correct Falcone case for it - constant mesh gears, 1 piece crank, no broken lug etc.  So I asked, what was the GTV case number?  34571 - only 28 500cc engines from mine!  Maybe just a few days apart on the factory floor!  I just had to buy it.

It arrived last week:

     


It's not a perfect match, but it sure is close!
