Thought the four-stroke wouldn't win the hearts and minds of motocross riders? Think again. The Yamaha YZ-F is starting to turn heads in the two-stroke world. Don't think for a minute that the only difference is the fuel composition. There are a few new tricks to learn, but as they say, the best place to start is at the beginning - starting the beast. The key might take a bit of conscious effort because in the two-stroke world you do something instinctively: goose the throttle. That will get you into trouble on a four-stroke. Don't-do-it! Instead, heed the process... Make sure the tranny is in neutral. Then make sure the gas cock is open and open the choke. Now you want to load the compression. Do this by slowly kicking it until you feel it come to a hard spot. If you try to kick it hard you'll suddenly gain a painful new respect for four-strokes. Now engage the compression release and ease down on the kick starter just a hair until the piston just past top dead center (1 to 2 inches in most cases). Let the kick starter rise back up to the original position. Now disengage the compression release. You're ready to crank it up now by a full smooth stroke on the kick starter. If you've done everything right, this baby should be humming. If not, start over. Practice makes perfect. Is the YZ-F's engine already warmed up? Not a problem, use the same procedure, making sure that you use the hot start button. Remember to push it back in once the engine starting is successful. Is the YZ-F's engine very cold? You might need to just give the throttle a tiny bump. Why? Just to give it a taste of fuel in the top of the stroke. This is the only time you are safely allowed to do this. After you and the YZ-F become best friends, this will be instinctual. Keep your eye on your YZ-F. An unscrupulous competitor might just compromise you by giving your throttle a healthy twist. Good luck starting it after that! Finally... follow these tips to the tee and your YZ-F will start faithfully every time. It just goes to prove that you don't have to have the overhead of an electric starter to ride a four-stroke.
