If jetting is not causing your issues after the easy stuff/plug fuel cutout switch damage wiring etc maybe refit the stock flywheel ignition to see how it runs
Did u do the kipps bolt mod and set the kipps valve correctly ?

Thanks Dave I was thinking the same thing about the stock ignition setup. I did do the kips bolt mod and am fairly certain that it's all working correctly.

So I moved the needle clip up into the second spot and the bike starts a ton easier. I had the timing back at .080 btc and it felt flat on top so I advanced back to .087. Top seems good now and bottom isn't teriable. The biggest problem now is that the bike surges like crazy. I turned down the idle but it doesn't seem to help. I was thinking about switching the pc pipe for a fatty to move the power down a bit. I'm wondering if I soupd move the needle clip back down and jet down accordingly. Are their advantages to doing it that way? Any idea on the surging? Everything is new no air leaks.
Thanks.
Pmcg:
After some re reading looks like the surging may be caused if I'm lean? I think I'm going to order a bunch of smaller jets and swap em out tying to keep the needle on the 3rd clip. Any suggestions from the experts?

Ok, that is the last version from 96-04
I'd go 52 165 clip in the 3rd position.
It might still be fat but better to go in small increments.
What you are looking for is your air screw to be set at 1.5 turns out and running good.
And, you want it so that when you let off the gas, the engine winds down quickly.
Be sure to make adjustments with a warm engine.
And then, watch your plug color.

Thanks Blaster! I ordered a 165 and a 162 and a 52 and a 50. I feel like I'm getting close and its nice to have eliminated the electric system.
