I've rebuilt a bunch of puchs and motobecanes, and now I'm ready to modify one. My goal is to get one of my motobecanes up to at least 40 mph, but I want it to be quiet.
My choice is between a 25 mph 50L and a 30 mph 50V. Both are running well, and both are completely stock. I also have, but yet to put on, the dellorto 16.16 SHA AV7 party pack from treats. Just looking at the air intake, I'm guessing it will be louder than the stock gurtners.
I've looked at the tuning spreadsheet, but there's nothing about volume. Suggestions?
