I just wanted to report something I figured out about kickstarting my Shovelhead that might help someone else.
This is my first kick-only bike, and I don’t have any experience with kickstarting. So far, starting it has been hit or miss and mostly random. Sometimes it would start in one kick; other times not. I wasn’t sure about things like when to turn on the gas, when to twist the throttle, how many priming kicks, etc.
So, I sat down and started thinking about exactly what I was trying to do. This is what I figured out, and it works on one kick now. (Obviously, timing and carb tuning has to be dialed in first)
I turn on the fuel, twist the throttle 3 times to squirt fuel into the intake, no enrichener , throttle 1/4 open, and give it two good priming kicks (ignition off) to suck the air fuel mix into the cylinder. Then, turn on the ignition, one more twist of the throttle, enrichener half way, throttle 1/4 open, one good kick and it starts.
I think what I was doing wrong was that I wasn’t twisting the throttle before my priming kicks. I thought the purpose of the priming kicks was for oil pumping. When I went to start it, there wasn’t hardly any fuel in the cylinder to get compressed. When I went to start it (ignition on), I was bringing it up onto the compression stroke, then twisting the throttle, and then kicking it. So, there wasn’t any fuel getting compressed. At the time I was twisting the throttle, the intake valve was already closed. The trick was to use the priming kicks to get the air-fuel mixture sucked in before I brought it up to the compression stroke and turned on the ignition.
I realize that for many of you, I probably just stated the obvious, but maybe it will help a kickstarting noob like me.
