So when I got my Puch Newport, I'd ride it around and it was fine - but when I'd get about 28 or so this deafening rattle buzz weird noise would come roaring out of the engine. I posted on here a few times and nobody could figure out what it was.
I thought what the hell... I'll put a new kit on it - maybe it's the piston. So I just finished installing my Athena kit, and I'm driving it around the neighborhood trying to slowly break it in. And low and behold - when I hit 28 REEAAAAANNNGHHHHHH. It's really a horrible horrible noise. What could be causing it?!?!
