Is the z400 liquid cooled? How big is the carb? Is your Z cold blooded? Was there a noticeable increase in power after your engine broke in? Does it seem that your engine makes the most power right through the mid-range RPMs?

As to that last question, I'll elaborate; When I get on it, in third, or even fourth, at first there's just normal acceleration, then at what I'd guess is about 3000 RPM, it really comes on strong, usually spinning the tires if I'm in 2wd and on any kind of dirt surface. I can only compare it to the power band of a 2 stroke, but not nearly as pronounced. Just a lack of low-end torque, then it builds into tire-spinning horsepower. Kind of wacky.

 

1-yes
2-39.5mm
3-huh?
4-oh yes
5-more like everywhere

 

Sweet, thanks for the reply. I think after my warranty expires I need to find a Z400 carb!
Bigger exhaust too...

Eiger riders everywhere... read this thread!

 

If your getting a newb carb get an Edlebrock.They look ugly but they increase power big time according to a guy that works at my local dealership and flat tracks.He had one on his kfx.
