WR400/yz426 motard questions

Hi all - I'm new to this. Have just aquired a yz426 motor which was in a trx 250 laeger frame - swopped it for my trx 330 kit motor -

mods are 444 wiseco 13:1 comp piston and gas-flowed head.

can get a wr400 for a good price.

I want to use it for motard racing and for the road.

Which gearbox will be the best suited? and which ignition - I can run total loss lights if the YZ is better.

What other mods can be done for more horsepower - rest of the class are 520ktm's and VOR's.

Has anyone tried fuel injection?

will then put together what is left and sell that motor (400)

cheers

John :thumbsup:
