All I have to say is "if you have a LTZ400 or KFX and want to beat a modified YFZ then get a Yoshimura Kit". Doug Gust's LTZ450 was faster than Kory Ellis's Alba YFZ450. Doug's LTZ out pulled Korys YFZ going up Mt. Saint Helens @ the GNC. Kory admits that Doug's LTZ450 was faster and had more power than his YFZ. So LTZ and KFX owners don't worry, Yoshimura is your answer. The same kit on Doug's quad runs about $2,900.00 (piston, clutch kit, stroked crank, porting and valve job, 39 or 41mm FCR, cams and ignition).

 

Aint it a pain that you have to put 3k ito a bike to beat a quad that you can buy new for only 1300 more msrp than the z???

 

Like Ellis's Quad is BONE STOCK off the showroom floor. Think about it, do the math, not that far off.

 

Yeah no ****!! Them zuki engines can be more potent than most think and most just like to eat-up the Hype!!!

[b]RPM[,/b] Kory's bike wasn't stock. I am just saying that for those who already have a LTZ or KFX, that there is still hope. I paid $6,000.00 out the door for my KFX400; my buddy paid $8,250.00 for his YFZ. Now that 2,250 more than my KFX. IF I take $2,250 and dump it into my KFX, the KFX will be faster than the stock YFZ.

 

CHECK PLEASE!!!!......We have a winner!!

 

I have a 440 with head work and cams and the 41mm carb and it beats the yfz in a drag race. Big deal but I dident spend 3g on it either. there are other motor kits that are the same as the yoshi and will make it come to life. I am very happy with how my quad rides and runs. I like the yfz and thought about it for a second quad but its not comfordable to me and I really dont care for the overall ergonimics of the machine. There is an a$$ for every seat and I chose mine I just needed to modify the motor to get what I wanted out of it. I really dont care who beats who in a drag and Dont care if Im faster or slower when it comes down to it on the mx course when im racing I just have to be the better rider and if im better on my quad then you on your faster quad guess what im going to win.

 

this might be a stupid question but i'm always confused when you guys say LTZ450, i know what you guys mean when you say it, but puting a yoshi on a Z considers it to be a 450 now?

 

I think they mean that the z450 as in the big bore kitted z400. Suzuki is going to come out with a ltz450 i think.

 

yes they mean when you put a 450 kit in it its now a 450. The 440 kit is the way to go. IT actually puts down more power.
