Be patient... Not a lot of supporters here like to jump to a NEW member. I would start with the CPS in the cam nose cone.. See if there is brown goo dripping out and down the wiring... Do you have a FSM???

I thought the 1999 RK's had the Twin Cam engine?
What carb is it running and other modifications have been made to the bike?
I'd manually check the ignition timing to be sure it's not too retarded. Then look at the plugs to see if it looks like a lean condition based on plug color. If they looks like it's running lean, check for intake leaks and then carb or fuel starvation problems. If it's really lean, you should notice other running problems as well, like hesitation before fully warmed up, fast idle speed etc.
If you choke it after it dies, does it start and run for a little while? An when it starts to act like it's "hot" are there any other running problems, like sluggish throttle response, surging, pinging etc?
