Talking rejet?

Hello all, I just completed a total rebuild of my motor with the first over sized piston. 0.50 mm over bringing my total displacement to 751.3 CC. I also have the V&H cruisers , however the baffles have burned up long ago. Now that everything is together and running I am a little lean. Do I need to rejet. If I do need to Rejet does anyone have recommendations as to jet size. I would not know where to start

You can just go up one size..so if you have stock a 132 main jet, go to a 134.

pilots are 38's I think so a 40 would be the next size up...but you might be able to use the 38's and just back out the enrichment screw (called tha air screw around here)

As you did not alter the intake, I think I would just leave it stock and check the plugs before changing jets.........

The plugs already show signs of running lean (very white) after only about 60 miles of riding. I think in the near future I am going to need to change the main jet to the next size up.

#135 I think is the next size(stock vn700) But I myself would go bigger than that #138 - #140. There not that hard to change jet change and are fairly cheap. I had to go to #140s in my 700 just to get to run on the top end with the cheap-ass fuel there throwing at us now days.
