Fitting a fork seal into the non standard front end of my B12 has brought up a few standing misconceptions about the parts used. It has been difficult to pin down exactly what's been used but I've worked from the following. It's a Kawasaki USD front end, I was told '93ish vintage which seems to pan out Stanchions are gold Fork seal is 53MM OD 41MM ID 8/9.5MM thickness Internal parts look same as a 750-P fiche sent over by Champ Front mudguard is in 2 pieces. The front section has 2 chrome front facing screws which are not recessed. The rear section has 2 chrome top facing screws and 4 bolts to the fork legs. OK so this *could* be a ZXR750L model fork. It looks very similar to the Team UKRM forks except that probably had 43MM stanchions. Just as a blindside it could possibly be a 750R-M fork but I do not know how to tell the difference. Pics I have of the mudguards on the L models deffo *do not look quite right*, I only have one fuzzy shot of an R-M and it *could* be right. Other thing that put me off the trail is the 6 piston callipers. The 750L 1-3 were all 4 piston IIRC. The R's were also 4's. All of a sudden I was thinking this could be a ZX-9 front end. The '94 B mudguard mounts looks about right. The '96 B4 had 6 piston callipers. BUT these stanchions are odd, at the top yoke they are slightly smaller than at the bottom yoke, was this a feature only of the 750. If the bolt spacing and disk sizes are the same it could be 750R-M forks with 9R callipers. I haven't found anything which shows me the 9R internals for comparison. I believe the fork oil capacity should therefore be 400CC of 5W per leg for the 750L's but I can't find proper manuals/fiche online for the 750 and 9R??
