77 Maxi e50 with 65 cc airsal screams like a banshee at WOT and when I lay off the throttle. I mean like imagine Ted Nugent on acid. Bottom end has never been rebuilt and wondering if this is what is causing the noise. 10k miles on it.
I have another 77 with less than 300 miles on it, totally original and stock that I can barely here.
Should I expect the screamer to quiet down after rebuilding the bottom end?
