installed the 450R carb and WOW.....!!!

I forgot to ask you Tina... Why you didn't put this in our own 400ex forum........ YOu have the power woman..

also for me, check the clearance from the top of the carb to the gas tank. I run a clarke oversized tank and I don't think the carb is going to work with the MUCH larger tank....

Here are some pics I took...
We need to attach a hose clamp to keep fuel from leaking, re are rejetting tonight so I can ride it tomorrow at the track that has the Payette Round for WORCS...Maybe Ill get some video of it...

[QuadJunkies]

there will be a hose clamp where that wire is .Troy said an Airbox will work, Il get more info in a few minutes on that

[QuadJunkies]

Im done with riding in mud(if I can help it that is lol) I dont run threw creeks ect so no air box will be fine for my application for now, in the future I may invest in an afteramarket box.

Choke is stil attached just cut back some....Im sure overtime we will make things look a little nicer on the set up as well...

Rico~~ heres the clearance question you needed.....sorry for the blur.. let me know if its too hard to see and Ill try and get a better one

[44oEX]

see and you didn't believe me

[QuadJunkies]

well, so much for testing out my carb tomorrow.. I blew a head gasket while jetting.....It hasnt ran good during a race and had a weird noise, now we know what the other noise was..... Im not sure if its due to a bad jug or the Gasket ect.... We may go back and just put my 426 back on... I was REALLY looking forward to trying the 440 too...

Did I read it correctly that you DITCHED the airbox?? Meaning the filter is bolted directly to the carb??


Some say the 450R shocks are a must to put on a 400ex, even though the stroke is wrong, grinding has to be done, etc, etc.

You could prol. come up with something, the intake boot was a little short and the air box on ours was pretty much already destroyed so no big loss on my end. You have to replace the fuel line and you have to hog out the intake boot. Thats about it ...!!
