NM51,
I got this Offy From Langdon. It does appear that some grinding work took place in the plug area and that a roset welding bead is in place. If zinc is the exact same color as aluminum then I'll call Langdon and ask.
By the way, what are the two 1/2 inch taped holes in the Fentons? For heat to the carbs?
So you took a 4" hand grinder and made the changes? What was the disk made of? Can this be had at Home Depot or Loews?
I should take a picture of the bellcrank clearance.
I've put myself on the list for Patrick's SS exhaust system. Living close to the salt air coast sounds like a good idea. But I've never heard their sound. Has anyone here?
The waiting list is 30-90 days. I waited over 3 months just for the new spring set from Patrick's.
