After so many years of modifying machines that didn't suit my needs, or my expectations, dropping thousands of dollars for parts and machine work, spending countless hours tuning and tweaking I have found its not worth it.
I had a 300EX, I didn't want a 400EX, I wanted to be different.
Four Stroke Tech fully built 352CC Big Bore Stroker
Custom Axis Shocks
and a whole boat load of other parts.
Do you know what I had? A machine that was a beast, was faster and more powerful than a 400EX. But, a 400EX with a pipe, jet kit, air filter, and a few other tweaks was almost there. A 416, 440, ect would run me over and I was maxed out on power. Not nearly as reliable and had cooling issues and other problems.
Moral of the story if you Pioneer doesn't meet your expectations or have enough power, sell it and buy something that does. There are better machines than a Pioneer out there for not a whole lot more money. Not saying the Pioneer doesn't make some people happy, but those expecting a power house super SXS, well you are gonna have a bad time.
