Convert your GZ250 into a 346cc!!!

First off all - I'll give ya a tip - don't ever drill Jets anymore. Many people on this board, including myself tried this at firstm and its just plain dumb.

There are jets for everything , drilling might save you a few bucks, but can cause more damage than help....

The engine in the GZ is from the DR250S (dual-purpose bike). I'm sure there are all kind of stuff that can be found to fit this engine, since it's a smaller version of the DR350 , which had a huge aftermarket possibilities. U don't wanna get to "pipey" cause you want to keep it reliable. I know a Suzuki expert that will definitely have some opinion in that matter. There's many other area's to improve in the chassis, so don't worry about it.

Oh but wait, ... I found one answer here.
Power? More power you say?

I am having mine done in a few weeks. Im ordering the parts, and having my own mechanic drop it all in.
Ill have some photos for the process, and I also found a way to extend the fork, found beautiful whitewall tires, found the PERFECT K&N setup, and a way to increase the rear tire size a bit.

These mods, along with a new OEM sprocket, a hotter cam, a z bar, braided hoses, having my engine case dipped in chrome, a chrome battery box mounted, side plate holder, seamless contoured seat, custom grips, fork stabilizer, Euro hand controls, mini tach, tons of white (hidden) LED lights in the frame, custom pipes with mini mufflers wrapped in black, .. man. Its all coming. This is going to be a show bike for sure.

If only I could find someone to help me cut the front fender properly. NATE?!
