Nice tuner!

Install on my Yamaha Stratoliner was very easy, took less than 30 minutes. Luckily the tuner for my bike uses a 6 pin connector and not the injector connectors- so many seem to have a problem. Operation and tuning is easy. No PC needed and you can tune any time you want, even on the fly if you were to mount it where you can operate it while riding. That's not happening with a power commander! My bike runs much smoother and crisper now, throttle modulation is smooth and predictable. Fueling is much improved over stock. I have owned this tuner for about a month now and no regrets. Its exactly what my bike needed. *IMPORTANT* The Wiseco instructions for my bike are generic and not bike specific and neglect to tell you to disconnect the 02 sensor, which you SHOULD do. The Dobeck Performance web site (they make this tuner for Wiseco) is MUCH better for install and tuning info.

The moose kit was a pretty simple straight forward rebuild kit. Whoever had the bike before us had jacked up the jets and this kit brought it back to stock and had all the necessary seals and assorted goodies to complete the rebuild. It's a kit so if you don't have the skills with tools, why you're looking at stuff like this is a mystery but simple, great fit.

Before I bought this I was hesitant if it really worked. I installed the quickshot 3 on my '05 yz450f and it's amazing the difference! It starts up hot or cold with 2 to 3 kicks, idels smoother, still has a very slight bog when I pin it, but it almost seems to completely eliminate it and I definitely feel a difference with low end! The QS3 with a tuned carb makes a huge difference in the feel of the bike! It's worth buying!
