Wanting to possibly install a yfz fcr carb on my 04 450R. What do I need as far as an intake adapter or hot start issues? any help would be appreciated.
Yep, what ^^he^^ said. I run a yfz carb as well. I did have to go to a smaller fuel line though. If you want to run an aftermarket intake, you'll need an adapter like the noss, rat, dasa, etc. If you want to run an airbox, you can install an 06-newer airbox and boot with no other mods.[/b]
Two of the holes match up and one doesn't. I haven't got the whole thing back together but there should be minimal modification. I was told i might have to by the 06 or newer carb boot that goes from the carb to the head. I am still in the works on this. You should see a lot of difference with throttle responce using this carb. I can post pictures as i go so you can do this mod if you like.if you put a 06+ airbox on a 04 05 r i know it will match up to the fcr without using any adapters, but my question is when you put the newer 06+ airbox on the 04 and 05 does the mount holes line up or do you have to modify it? if so how did you go about modding it?
thanks for the help[/b]
