Beeb, I stumbled upon and quickly purchased a 92 FZR400RRSP and am looking for some feedback from those that know these bikes, I do not. Always wanted one but don't have any experience with them. My experience is in the OW01 /YZF750SP realm so I know Yamaha kit/YEC/SUGO. It is a zero mile bike, apparently the full SUGO race kit was bought and installed and then never raced. Was stored in Japan then shipped to the US in 09 where it remained in a collection. Currently living in Norway so haven't seen the bike but a good friend inspected the bike and confirmed it is real. If anyone with experience with these has observations or recommendations I'm all ears...Just trying to figure out exactly what I got. After 24 years of inactivity will need some love to get back on the track.
Very nice! I haven't seen that airbox before. I like the replaceable upper fairing stays as well... need to track those down. Here in the US I'd steer you towards Steve at Speedwerks for knowledge on that machine. Also, I call dibs if it goes for sale, which I will then have to retract once I realize my wallet is empty.
Interesting airbox. I built one like that for my racebike, but it had a different intake (it was aluminum). Interesting also that it has working EXUP (apparently) and the stock sized radiator. I had to put a ZX-7 rad on mine to keep it cool here in the Southeast US. I worked on a couple SP models that my customers had, they are nice frames and swingarms. Likely a very low serial number on that one.
That EXUP is *rare*. The standard FZR-era EXUP is an oscillating wedge across the 4-abreast header; what you see there is a square-4 arrangement with 2 butterflys on each of 2 stacked shafts geared together.
Rick, I was wondering about cooling on it, considering it also has rad fins cut for the ramair. How easy is it to mount a ZX7 unit? Don, Have you seen an EXUP like this before? Wondering if it is a race kit item. Trying to source a YEC manual for the 400. thanks beeb!
It is a kit exhaust; it allowed bigger headers and an improved collector design. BDK RaceEngineering offers headers and their version of the kit EXUP valve for the 400.
If the guys over here can't get you sorted out, give the crew at BDK Race Engineering a call. They seem to have one that goes like hell. http://www.bdkraceeng.co.uk/Bike1.html
I did a YZF600 radiator and it was pretty easy. Bottom outlet I cut and turned 90 deg welded it and it lined right up. Top inlet I left stock and used a few elbows bought at lowes.
SSRT, thanks for the info mate. Is the rear shock rebuildable? Anyone have a nice aftermarket unit for sale?
Not that hard. Had to fabricate some aluminum mounting brackets and used two hoses I found in the shop (this was many years ago) from some other bikes, just to get the bends right. Did it easily in an afternoon. I usually had to run tape, but when it was 105 at Tally or Memphis, the bike ran perfectly cool.
