I rarely post here, but don't let the name fool you, I do own a Banshee. I run a small shop out of my home and encountered a problem with an '02 Banshee that belongs to a friend of mine. There are some mods on this quad but I don't think they'll have a bearing on this issue. This quad has always been a little tough to start in cold weather, but once she started everything was good. The quad came to me to replace the clutch, do some suspension work, and freshen the top end. A new set of pistons and rings brought compression right back where it should be, there where no other mods or changes made during this rebuild. Now, here is the problem. Temperatures around here have been bouncing all over the place, from 20 degrees to 60 degrees. If the temps drop under 45 degrees, the quad refuses to start. I have drained the bowls and tank, put in fresh gas, ran a check on the stator, and bumped the pilot jets up from 25's to 30's. None of this has helped if the temperature falls below 45. If it is above 45, it runs just a tad rich at idle and just above idle with the 30 pilot jets installed. Using a heat gun, I started by warming the CDI, then the coil, then the plugs. Still no help. I then aimed the heat gun towards the air filter, giving it just a little warm air. As soon as the motor gets a shot of that warm air, the quad will start on one kick and idle perfectly. It just doesn't seem like a jetting issue to me, since it does run just a little rich above 45 degrees. One other thing that I have noticed consistently, when the temps are below 45, the quad will usually fire for a split second on the first two kicks, then nothing. Any help would be greatly appreciated.
