Im putting a yz426 motor in a ex frame,300ex that is right now.Im waiting on the oil cooler,i just wanted to do something different,instead of the 400ex frame.;)

for me it costed $270 to get the frame moded and the mounts made and the extention of the kicker.

a radiator cost $50

for me my motor costed 1300 with elec/header and pipe/carb/

you can use your 400ex throtle.

the stock oil tank works.

muffler needs to be moded. I also had to shorten mine.

The muffler has to be moded. I just twisted my muffler sideways and hose clamped it to the frame.

My radiator is zip tied on.

Yeah not fully dun yet;)

i added teh 400ex oil cooler for added cooling.

muffler. Its tight against the plastic

Not bad 5 star...looks like a fun project, the machine looks awesome! So would you say it was worth it? Also any other little mods need to be made?
