I think the 'wire brush resto' would be ok... when surface oxidation occurs, it protects the metal well as anything else, just as long as the engine isn't put away wet...
Well, the frame paint looks so nice, maybe you could paint a few pieces of the tin, the same color???
So a 'Wisconsin Robin' is not built by fuji heavy industries????
NOISE !
That's probably number 46 on my list of projects... a home-made muffler that is not HUGE and will do a good job without robbing too much power from the little engines.
For years, I rode motorcycles like they were stolen.
It was the loud noise that got people upset, first.
Then, it was difficult to run from enforcement with loud pipes!
lol
Yesterday, a chopped deuce coupe made a couple passes through the neighborhood. It had a built SBC in it, with straight pipes... WHY?
I'm sure the guy enjoyed the rumble, but no one else did.
...and he was goosing it! lol
There's really no reason not to have a quality muffler on a thirty thousand dollar hotrod !
I hope to try a larger diameter header tube, with header wrap, then a fabbed glass-pack with a pivot washer on the tail end inside the tail pipe.
A few weeks ago I gathered a bunch of stucco mat scraps from the res construction project, across the street. It should work well for fabbing a glass-pack.
Best
