    Pleasantly surprised...(KFX450R)
    I was a little skeptical getting this. I wavered back and forth for a while, and finally decided to go for it. I have the FMF Power Core 4 slip-on, K&N filter and well ventilated airbox lid, and felt it ran pretty good for having no motor work done. After installing the programmer, I took it out on a deserted paved road near my house and blew through the gears in a hurry. I knew it felt faster, but wasn't sure just how much. The next day, I took it out to a riding area that I go to once or twice a week, so I know what my machine can do on pretty much all the trails. It is full of moderately steep hillclimbs, drainage berms and lots of winding sections that allow you to use varying throttle the entire ride. I could really feel the difference from the last time riding there. Undeniably quicker through the gears, better torque, and simply more overall power throughout the RPM range. The only small problem was when I first started the machine after install, it would not idle without the "choke" knob pulled out. I figured out that I needed to turn up the idle screw quite a bit higher than it was set without the controller. Now it idles normally, and starts about the same as it did. Can't wait to hit the Saint Anthony dunes as soon as I can to see how much better I can climb Chokecherry...right now, I can pull 3rd gear all the way, but speed has slowed nearly enough by the top to almost need 2nd. Hopefully I can keep 3rd pulling hard all the way to the top now!

    Huge improvement!
    I bought this to help out with the terrible bottom end torque of the injected yfz450s. With the air box lid off and the core out of the factory exhaust, it made it a different machine. Best money I've spent on a bolt on part!

    Woke up my Honda 700XX
    Why didn't I do this years ago, this thing is easy to install, great instructions that were specific to my bike but the print is a little small for my old eyes. They even have colored pictures using your exact bike. Easy to program and in each different program mode one can make quick adjustments in the field for any load or throttle position as needed depending on the mods that you have on your bike. Completely eliminated the idle to full throttle hesitation that all OEM 700XX's have, fuel economy went down but it was never good anyway, guess I need to get a desert tank for it next. Good product for a fair price with a 2 year manufacturer warranty. the only thing I was disappointed with was there was no sticker-yes no sticker.
