It’s running great now. Tightened up the motor mounts and messed around with some jets. The rattling is actually a broken piece of the baffle inside the exhaust shaking around like crazy. Either I’ll get a friend to cut it and weld a new one on or replace the pipe. Still should probably pull apart that variator and find out why the weight arms don’t move so well. I personally think it’s variating appropriately, but I worry about one weight’s hinge being stiffer than the other’s, causing an imbalance/ extra vibrations. This thing rips super hard! My Instagram is snclvn if you want to see a little clip of it running.
