I am so excited to show this picture to you, the R12 exhaust and the headers arrived back from Jet Hot today, spectacular!
No discoloration from the heat.
Thanks,
Shane
I just read in BMW Motorcycle Magazine that a guy bought these same R12 repros from Poland and had big overheating issues with them. His actually went on an R12, but that was the same displacement as your R75, albeit with a much smaller carbs and compression ratio
If you want to check it it's on p.72:
"The engine started normally, but within minutes, overheated so much that the chrome on the pipes burned. Greve finally discovered how to stop it: The Polish reproduction pipes had too many baffles. A few hits with a heavy rod through the mufflers gave the old girl air to breathe."
May want to have Josh check it out
