Timing looks good. The majority of 650 DP's come with 67 pri. jets and either 73 or 76 secondary jets and also a 6.5" power valve and .028" squirters. I know you jetted up and I think your close looking at the plug pic. Not sure how much vacuum your producing with that cam, so i'll guess the PV is close enough to work well. My only thought at this point is you may be helped by a .031" squirter since it's a small carb on a fairly big plenum manifold?
