This engine drive gear sucks it only take a certain chain I’ve tried filing it down for this chain . No such luck . I ordered it plus some other stuff. It’s been nice in 50 the last two days I’m chomping to ride it but can’t. Soon it will be done. Looks good too . I’ll take pictures when done.
I've come across those, almost like they were made with a worn die. Like only the cheapest chain fits, but breaks easy, the good chain skips every other or every third tooth.
