Hay guys, got a 2000 shee, boost bottle, fmf fattys and powercores. Just did a top end rebuild wsm internals, cylinders done through F.A.S.T. Fresh rubuild on carbs, jetting at 280. Elevation at 1000ft, 32:1 mix. It runs fine with full power but spits oil out of exhaust, is my jetting to rich? whats the problem here?
