Just wanted to get an idea of what clutching you guys are running with the 600 2012 pro 13.6 PAR head. Right now I'm running 56 stock weights, stock helix, red black secondary and almond blue polaris spring also dropped to a 19 tooth sprocket sled pulls strong but would like to see a few more rpms only pulling about 7800 bouncing to 8000 if I hit a track pulling a hill. Don't really want to drop any weight so wondering if a different spring combo would work better. Thanks for the help also really impress so far with the head saw 10 psi better at 8000 feet and sled jumps hard off the line will pull a stock 600 about 2 sled lengths also I'm riding at 8000 +
