Hey everyone! This is my first thread here on dirtrider and I have a few questions I'd liek to ask everyone. First off, I have a 1986 YZ80 2 stroke that my dad bought me when I was 13. Im now 18 so she's been in my possesion for a little while now. I need to ask about some performance mods becuase even though she's strong, its still only a 80 hulling my ass around. First off, I need to ask about exhaust. Mine was always loud and upon removing it, I found the metal gasket for the head to exhaust was broken. I bought a new one (10 bucks! and then i lost it and had to get another). After the new one, my exhaust hasnt fit right and doesnt want to bolt up without manhandling it. And then, the muffle doesnt want to stay on since its pulled weird, and theres an opening where they fit together. Any suggestions of a new setup?Thanks, Nic.
