oh forgot about the carb springs,these muthers are huge,the 44's,pull the spring's out of the carbs and CUT 2-3 coils off the length.Makes it way easier on the thumb.

99 was ZX chassis, the steering stem is stronger. On the S-chassis sleds, they bend right at the upper bushing to the handlebar mount. When you Pull on the bars, all the force goes to the upper bushing. The steering stem is Hollow. After my 3rd stem, I cut the top plate off my stem, and shoved in a piece of solid stock as far as I could, then welded the top plate back on. this stiffened it up HUGE. I now have a 8" riser and No bending whatsoever. Added maybe 2Lb

there was a zx in 99, but the 670 was never in the zx chassis stock...
unless i didn't read enough of the previous posts..i'm sorry.


setback the skid, d/r for a 2" lug.
get the bars where you feel comfy.

Yup, your right. For some reason I thought there was some 670 ZX's in 99. I HAVE seen 670's in ZX chassis, but they musta been transplants then.
