with a different sub frame the one on the z looks like it will be able to do this allows easy access to alot of parts on the quad also makes easiers to clean

air mod

this is not a 400ex ari boot it is a 250r filter and uni outer wearer i was using this det-up on my 250r,s for the last 2 years this is what we ran on lonestar no-link chassis when i was tearing down my z i noticed how small and the crappy way the air filter hooked up and tired this it all most looks like its made for the z

tie rods

heres the pics of all things that i found last lite has the tear down process is allmost complete tie rods off of 250r will bolt up you have to use the whole rod with ends, 88 250r hubs will bolt right on the z the rotors are just a little bigger, the steering stem bolt at the bottom ia just is about 3/4 longer on the z, and yes 250r a-arms will bolt right up to the z you will need to make some small spacers see pics. i forgot to check the bll joints will check later, new air box set-up, and the front bumper mounts are very close you could make a alum bumper like ac bumper fit right on the z with little tweaking of the bumper, brakelines off the 250r work on the z more will follow air scoops,flip-up rr fenders,gussets,battey cable quick disconnect,head lite replacment hood,

done with the tear down

took alittle longer than i thought it would heres the last of the tear down pics next off to the sandblaster then to the cad machine to make gussets. and start tearing down that motor to make some more h.p. just a few things that i would recomend to do , make sure to use good sockets and wrenches man they use alot of locktite on these suzuki, get some neverseize on that swing-arm bolt a.s.a.p or you will be buying a new bolt, man those 4 stroke motors are heavy .
