400ex yz400f hybrid

[lainracing]

Need to know what intake manifold to use on a 400ex frame. the motor is a yz400f conv. to a 426- I think that the cross bar that the rear shock bolts to will be a issue. Its what goes to the motor to the carb. can anybody help???

i used duck tape and aluminum cans

you cant be serious can you? thats only about the dumbest thing i have ever heard...even from you, blue450yo

im told big radiator hose but i tried and it dont bend.

You need to notch the frame and take that triangle suport out for the tube to fit. Then you need to add suport cause from notching makes it realy week.

Its still a tight fit after notching the frame.

Easiest thing to do is cut the frame and build a bridge. I think thats what its called?
