yz hybrid kickstart and oil ?

[atvfreak400]

does anyone know if a yz250 or 125 kicker will fit on a yz426? I just want something a little shorter so I don't have to trim my fenders so much, and how much oil should I try to get to fit in my oil tank, I got to make my own and I'am very limited for space[using 450r rad in 400ex] any help would be great

I cut and reweld mine, works great with the decompression cam
I believe the yz250 will fit.
My oil tank holds 2.75 quarts.

how will I know when I have enough oil or do you just put as much oil in as you can or can you get to much ? What do you think about using the 400ex oil cooler.
