I have recently rebuilt a Broken Innova that I acquired and as it had the silencer adaptor but no silencer I purchased a male fitting 1/2" UNF Silencer.
I does not fit - wrong thread
My other Innova that has the original adaptor and silencer is at my secure lock-up and I can't get there for a few days so I can't make a comparison
I have always taken it for granted that these old aftermarket adaptore were 1/2" UNF
My Question is - what is the thread on the old aluminium silencer adaptors?
Thanks in confusion
