Hot starting is best aided by two things:

  • A properly jetted carb
  • A familiarity with your bike and an understanding of what it needs when starting hot.

On the first point, the important part is the pilot circuit. A lot of people run way too big a pilot so as to be able to snap the throttle open like a goon instead of learning to roll it, or to make every trace of decel backfire go away. The pilot jet helps throttle response, but if you have a real problem with that, the pilot is not the way to fix it. Likewise, assuming your exhaust is sealed of any significant air leaks, a little decel popping sometimes is an indication that you're jetted about right at idle. Interestingly, a pilot that's just a bit lean will help prevent stalling when the throttle is closed suddenly.

On the second, you just need some time to understand when the bike is likely to respond to the hot start lever, when it will start better if the throttle is cracked open a little rather than fully closed, how to clear a flood condition, and when it will start more easily without the hot start. Seat time, understanding engines, and being observant will do that. It's rare that I can't get mine moving again after 4 kicks. The main thing is not to make it more work than it is.


+1, familiarity with the bike will help make starting much less trouble than many make it up to be. One thing I will ad is after stalling my 2008 will have a tendency to start easier in neutral versus in gear.

With mileage, I can get anywhere from 25-40 mpg depending on the terrain and the speed I'm riding at. My last race with a speed average of just under 20 mph I averaged about 30 mph, and the terrain with intermediate/hard dirt with a bit of soft dirt/sand wash.

That's very definitely true of mine, too.

it will kick over easier, and faster. even with the clutch in, you're still getting some drag from the plates.

Well, I made the plunge. There's an 09 YZ450F sitting in my garage now where my KTM 250XCW used to sit.
