Bump the timing up some. 32 total leaves you some room to go up in the initial and stil be OK on the total.
a 750 DP comes with 72/80 jetting. You are way under that now. I would like to see what it does with the stock jets as I bet you have the idle mix screws way out right now, and might even have the idle speed set high. Resetting the timing should help that some.
