Installed a Thunderslide kit on my '97 Sportster 1200C. Jetted to 180 high speed and 45 slow.
Idle mixture is a little over two turns out.
I finally got out on the highway today and it has a miss at the high end of the rpm before shifiting and while cruising at 57 mph or higher. Seems like a surge at times. Will add a SC breather kit this week. Idle mixture is a little over two turns out.
