Adding another toy to the toy box. I just picked up a 1986 lt250r with a fresh bottom end and am putting it back together. In the process I found, after the new swing are pivot bearing went in the small crack in the casting where the bearings are. Looking for opinions on fixing and repacement swing arms. I understand that the '86 don't have the best swing arm. Also looking for opinions on exhaust. Right now I am just looking to replace the DG muffler but eventually when the $$ is there I want to do a pipe too. Who out there is making good stuff for these bikes? I have been told buy last owner that it has been bored .30 over and ported. Also what is the mix ratio as I am used to my Polaris Scrambler that is injected.

Thanks,
Kevin
