YES!
With just the needle shim, the free flow stock air mod, a re-jet of the carb, and drilling holes, I got my GZ250 on the Los Angeles Freeway today up to 80 Mph (More like 78-79Mph.).
Yes, it is possible, and no, I havent even done the freeflow exaust yet. I plan on putting a large K&N filter on it, finding a perfect free-flow pipe, getting a custom made jet-kit from The Motorcycle Doctor in Torrance, and drilling out the carb a bit more making the jet larger. As well, I am going to add a 16 sprocket front disc, and add a better rear tire.
I want to put in a hotter cam, and then have it tuned once more on the machine.
I have no doubt that this machine will reach 85Mhp easy after these mods. And get this, .. its not even broken in yet ...
I love this bike.
