I'd check for vacuum leaks between the carbs and the heads, I'm having the same kinda problem along with a dirty carb. Check your rubber sealing parts for dry rot, cracks, rips, or pinholes. Also check your intakes from the carb to the heads for pinholes at the welds maybe. Check that your clamps are tightened down good. Are the carbs clean? Could be your Filters/velocity stacks are leaning your mixture out too much if the bikes not jetted for them.
Hope it helps -
Ok so my carbs are clean and floats are functioning properly most of the rubber is brand new on it and from what im reading in my bible I think is either some sort of ignition issue or a timing issue. Was going to buy a compression gauge tomorrow just to see where im at and go from there.Comment

The Cycle-X twin carb set up you have is the culprit. Because the intake manifolds are uneven you'll always be running rich & lean on two cylinders. They're a fucking bitch to tune properly! I know because I've been dealing with the issue for a while now and opted to buy some OEM round top carbs and will be putting those on soon. Do a search on the honda chopper site and you'll see countless threads about the same issue. Your compression needs to be solid as fuck for the bike to run somewhat decent with the twin carb set up as well.Comment
