    guess who's next for the 450r carb? now to decide how to hook it up. Can I use a 450r airboot and modify it to fit the 400ex air box or what?

    no just enlarge the stock one with a sanding flapper wheel. you need to do the intake to. also for fuel line just use 3/8 auto fuel line. put a sparkplug in one end to enlarge it to fit the very large 450r inlet. its a little big to the petcock but i used a hose clamp with no probs. you need to move the airbox up about 1/2" also.

    if the airbox is moved up a 1/2" then do I make a steel bracket so it stills connects to the back or what?

    some people say to take the rear bolt out push it up(forward) then put the bolt back in with a big washer to hold it. i tried this but it came loose. so i got one of those small torches and melted the plastic rear airbox bracket a little and bent it back. then i melted the tab a little to make the tab flat again and it works great. you can barley tell its modded.

    No, if you can leave the airbox open. Yes you will need a bigger main and a bigger pilot jet.
