Stock for stock, the predator is quicker and faster. I rode a piped Z shortly after I got my Polaris. The Z is a great machine, but the Z that I rode, didnt have nearly the power of the polaris or my Honda.
I raced a piped and jetted Z400 up Comp Hill and Sand Mountain and got him by TWELVE lengths...
Then yesterday, I raced a Z400 with the full Yosh 453cc kit. First time, it was all I could do just to tie him, but after a few more times practicing my launch and getting the whoops down, I was able to beat him by 2-3 lengths. Rider weight difference was about 80 lbs, though (his weight over mine).
robg i all so raced z400 with 453 kit hotter cams yoshi cdi box and was tite race. i could get him most of the time thats before i put the air force kit on i will get him good next time. and i tide a fellow on a predator that had ported head and running on alchol. alchol a big deal around hear, not for me i like out running them boys on alchol makes um mad.
my dumb ass friend has a z with pipe and jet kit, he only thinks hes beating me, but as soon as i hit 3rd gear then he realizes his z is eating my exhaust. consistantly he could take me out of the hole, but thats all, unles i missed all 4 gears he didn have a chance. one race he even jumped the light and i still caught his ass and went around
i am a first time rider
and i had my pred for less than a week.
And my buddy has a z, he's always been a little cocky
so we raced on pavement and he took me until about 3rd gear
then i blew by him
And he even tried drafting behind me, which worked until he pulled back out into the wind
And his z would just drop back 2-3 lengths behind me
he drafted three or four times before he just gave up
it was hillarious.
i have a z with lots of mods as seen below, and i still tear it up with my pred. with my dad riding it, i beat him by 3-5 lenghts depending on my launch. OH, he weighs 80 pounds less than me! my z really runs good too. i raced a guy with a 450 z and beat him by 2 lenghts, but i rode the guys quad before we raced and didnt think it was as bad as a 450 should be. i think he may have only done a bore kit and nothing else (cams, valves, port and polish).
