I'm a little confused on what this 15mm intake is going to get me. The bike came with a 12mm bing and what i thought must be a 12mm intake.
I measured the opening of the 15mm intake I got from 1977moped and it measures 15mm (round) exactly on the end that connects to the carb. The other end is rectangular and larger. (what that gets you? the case has a round hole)
The intake that came with the bike also measures 15mm on both ends and they both have round openings. I noticed there's a '14' raised in the casting. Don't know how I never noticed that before. So this must be a 14mm intake. Why it mesures to 15mm I dont know, The ID and the OD of the round holes look the same between the intakes.
I haven't had much time to fuck with this yet to be honest (remodeling house) but I'm gonna just try and use the old intake with the 14 written on it and put my new 15mm carb on it. I got this sweet looking paper/screen/chromed out air filter that I'm dying to see what it does for me.
