Thanks for your comments.
When I got the bike, the muffler was already gutted and it was already re-jetted; I do not know what size jets are in it.
The air filter is a “Pancake Air Filter Triumph / BSA - center mount” $29.00 + $5.05 shipping, from ebay seller lowbrowcustoms. It was hard to mount so I should have gotten an offset mount instead of center mount.
I modified the exhaust by cutting the lower muffler after the back cylinder pipe junction, cutting the top muffler at 10 ¾ inches, and then joining the two together, so I no longer use the middle section of the muffler assembly – which reduces weight by 4.6 lbs plus I left off the rear chrome non-functional pipe which weighs 1.0 lb.
The performance and gas mileage seems about the same, but the sound was not as good as the stock muffler (gutted) - and it was louder.
I doubled the size of the aftermarket baffle and it improved the tone (not just the loudness) to where I don’t mind it, but it still seems to sound “harder” than the stock muffler, whereas the stock gutted muffler assembly had a smoother, more powerful, more pleasant sound - at 65 to 70, the sound reminded me of a Moto Guzzi.
It still sounds “good” – but the stock muffler sounded better.
I will probably try a bigger muffler, and see if I can get it to sound better.
