Had a old school welder do a pipe same way.
Brazed it I guess, then plated it.
1978 yz250 pipe. Really thin metal

They had a good old welder there, but he was in out of town, a young dude did it...

That ground strap looks like one your free rang goats eat a can of brush on electrical tape and took a dump on your engine. 

But more important, who installed that highly enginered shop floor? must a been some of your new border jumping enginering students

I bought this 40's farm 5 years ago, maybe it's time to put some money on the garages ;-)

Ok, this is my final jetting with by pwn 35mm:

 

145/42, clip second from top,+5°.

 

Run goods, egt goods on a long hard pull.

 

With the new porting (125/195) the engine have more top, less bottom as espected. I can really feel the increase in power.

 

I also have to play with the clutch more. Last year, lp and +9 was giving me some bottom ;-)

 

Pretty satisfied with the setup, here, i use the shee like a rallye machine , so it fit perfectly.

 

Next built will be 5xx power valves.

Max egt, rpm and water temp after a long pull.

That engine is pulling fuel very efficiently and a strong signal, judging by the final jetting. Just my opinion but you may benefit across the board from bigger carbs . What needle are you running

I got a good wash and plugs reading, pull hard, you did a good job sir.

For shits and giggles I would try a d series needle if you get bored. You might pick up some bottom grunt under load .
