I don't like running the starter that long so I try to kick it as much as I can to start. Like I said this is after a complete rebuild and I am still working out the bugs nothing serious just little things.

The website that "wired George" runs has information about a relay modification that will also improve the combustion process in your engine by bypassing the corrosion in the wiring.
His website with the diagrams and parts is www.wgcarbs.com
He also runs a carb rebuilding service for motorcycles out of Texas and does wonderful things to the carbs.

I have also gone through the entire wiring harness and replaced any questionable wires or connectors. She runs great after starting. I just don't understand why its hard to start.

For four cycle engines to run/operate you need 1.Fuel 2.Air 3.Compression and 4.Ignition. Any one of these four go missing and it will not operate.

When cranking with choke on, do not touch the throttle. The choke circuit is designed to operate with the throttle slides in the full down position.
Would also use strobe-type timing light to check ignition timing and proper operation of the advancer as rpm is varied.
Good Luck!

In order to start the bike I have to give some throttle or it will just keep cranking. Spark is good. I am going to clearance the shims again to see if I missed something. Any ideas are greatly appreciated.
I also vacuum tested each carb, they are all set equally. I starting to wonder if my cylinders are leaking too much?

1) Measure the voltage across the battery terminals.
2) Measure the voltabe across the battery (-) terminal and the Coil (+) input.
3) What are the readings?
This will tell you what your ignition wire, connector and switch losses are.
Best of success.

Carb enrichener circuit may have blockage and need cleaning.
