[wedge]

I got a few different fzr400...so got round to stripping down one of my 4dx..I was told and believe it came from a well known iom racer...this is the thing it had a ram air box in white plastic with the scope behind the rad with some rad fins missing...has anyone seen one like this is it a yam kit piece

A photo might help bt ram air boxes are not uncommon on race fzr's

It's not BDK.... It's plastic and to well made to be a bodged job that's why I'm asking if anyone ever seen a yam kit one... I will try get pics

I've seen it done before on a race bike. There's a hole cut in the frame web where the coils are. There's a scoop that sits behind the radiator and pushes air up into the airbox.
I don't think it's a YEC part, if it was there would be part number moulded in and it would probably be black. I'd also expect flatslides and the air box to maybe enclose the carbs as well

So people ARE cutting that frame panel and not dying as a result? Mwhaahahahaahaha. That'll give me PLENTY of room for RAM air.

Pics would be awesome if you're up for it.

Frame not cut away

Very nice, I like the flatys!
How do you mount the carbs? I mean how do you tighten the hose clips to the carb rubbers?
I've got both a bdk and a kit copy ram air box that I've never used but can't see how to fix the carbs tightly.

I want to say BDK or someone else was listing using zipties instead of clamps on the rubbers as one option... I use boring stainless steel hose clamps from the local plumbing supply. With careful positioning of the clamp screws you can get on them with a socket and flex adapter to tighten them down even with the box in place.

Cable ties for me, 10 years and not one problem. Why make life hard and add weight :-)

Thanks I'll have a look at thkse options when I get the time......
