SOURCE: Clutch slipping while cold, when warm/hot, it operates great.

I have a 2000 Vulcan Nomad FI & had a very similar problem. In fact, it's a very common problem with these bikes. I fixed it by replacing the Clutch Spring. (As Described here: http://www.gadgetjq.com/clutch_spring_replacement.htm

It cost me $40 and 3 hours of time with an impact wrench.

SOURCE: wont run...

Any water in the gas? Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. Any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Get a fresh set of stock NGK spark plugs. Clean or replace the air filter. You seem to be pretty thorough in what you have done, but since plugs and filter weren't mentioned I had to ask.

Assuming you are getting air, gas and spark, and the timing is correct then it should run. Right? Not necessarily. Can the bike breathe? If pressure cant get out of the tailpipe the bike won't run. Mufflers can sometimes collapse internally. This restricts the flow of burned gasses. causing backpressure. If nothing goes out of the cylinder then nothing goes in.

Try removing the exhaust pipes. Now see if it will run. Get back to me because I would like to know what you find.

Sounds like you have a fuel delivery problem. First check to see if there is a inline filter from the fuel tank to the carburators that is partially plugged. If not, you will have to remove the fuel valve from the fuel tank and clean the screens on the fuel pick-up tubes. The only other thing that would cause a fuel delivery problem would be the vacuum line from the carburators to the fuel valve has a split causing insufficient vacuum to open the fuel valve.

SOURCE: Bike wont kick start or idle , it will coast

first drain the carby, then set your air mixture screw 2 turns out, from the fully turned in position. The starting proceedure is as follows, when the engine is COLD, turn on fuel, pull on the choke fully, and kick the engine over. DO NOT use any throttle, when the engine is cold, and the choke is on. Remember Choke on, NO throttle.
When warm, no choke, and a little throttle when kicking.
