My 450R carb installation

[r-exrider0003]

yeah i'd probably buy one if the price wasnt too bad... just got my 450 carb a week ago, and i havent even tried putting it on yet...

Those interested in an adapter, PM me I still have a couple left.

Remember:
They are intended to be a press fit onto the carb side and solve two issues when putting a 450R carb on the 400EX, first is the airboot size, the adapter makes fitting the airboot (air filter side) easier. The second thing they solve is the length. With the adapter you will not have to move the stock airbox location!

how much are you selling the adaptors for?

For you guys looking to do the swap get yourself one of zrpilots adapters. It will look totally stock, like honda designed a 42mm carb to on there. I got one and it only took maybe 3 hours from start to finish. I fired it up on the first try and havent touched a thing. I thought it was a little big but its not, it will have awesome throttle response and this is on a stock bore engine.

Glad it worked good for you!!!

The price for the adapter is $45 shipped any where in the lower 48.

what do the adaptors look like and actually hook from 1 thing to another. I thought there wasnt really any problems with bolting the carb up?

they eliminate the problem of trying to stretch and heat the intake boot to fit the 450 carb.

Look on the first few pages. The pictures show what they look like installed.


And Exrider434 is right, the adapter helps accomplish two things:

1) Eliminates having to move the air forward 1 inch
2) Eliminates the problem of trying to stretch and heat the intake boot to fit the 450 carb.

I got zrpilots adapter and i can tell you it will make the install as easy as putting on the stock carb. The difference is also night and day just get ready with some big jets. I needed a 205 main and a 58 pilot to get my e85 mix tuned in.
