1993 CBR900RR rear drive axle assembly gap
So I noticed my original thread got deleted. This is a rather enigmatic problem I thought would be worthy of taking note of, especially since my mechanic, a man who's been working on bikes for 30+ years tells me straight up he doesn't know what's wrong and he doesn't want to work on it.

Here are some pictures showing the caliper mount rubbing up against the rear brake rotor and one of the sprocket side clearance and one showing the bowed swingarm. For those who haven't seen the original thread, the problem is about an inch gap in the drive assembly between the swingarm and a caliper mount rubbing the rotor. Please help this bike is amazing otherwise. Thank you. -Dan

Thank yuh Demon. Yeah could be an issue with the brake side spacer but the caliper looks like it can only move right a mm or 2 and therez a whole inch of space. If anything, I could have my mechanic machine a spacer with a LITTLE more width for the brake side which hopefully would get the caliper bracket to clear the rotor and still have a functional rear brake. Then therez a little less than an inch gap still and therez nowhere else to put any spacers. I just don't understand. The frame is fine, wheels are straight, rides perfectly, etc. It even handles really well and has no play in the rear with everything tightened down to bejesus. I just want to know if therez any foreseeable risk involved with riding like that for extended time. Such a weird problem...

That spacer was machined. I'll have to look into the wheel bearing spacer. I don't think dude looked at wheel.

Looks like your missing the correct spacer on the sprocket side, probably the one thats outside of the swing arm on the right side, or something about that size.
The brake caliber bracket only sits about an 1/8" to a 1/4" away from the disc so theres an issue with the spacer on that side between it and the wheel bearing.
The bracket itself generally sits against the swingarm so that parts seem to be about right.

Yeah, the mechanic said the bearings are good, no issues there. I looked at a schematic and the spacer does look a bit bigger. So, I started looking for spacers on parts sites and ebay. Nothing. Can somebody maybe recommend a place where I could get on or measure the width of their rear brake spacer so i can have one machined?

Found this. Wonder if it'll work? Can I get some pictures of Y'alls rear assemblys? Thanks.

Ok so I took her on a pretty big ride today (about 120 miles or so) and the caliper seems to be loose on the bracket which is digging into the rotor more. Still no play in wheel, everythings tightened down right, smooth ride, smooth handling. Do notice when I let go of the front, bike SLOWLY tracks to the right A BIT, but I've had way worse alignment issues. I'm thinking now it could be something with the cush rubbers getting messed up or the rubbers inside the wheel hub or still could be wheel bearing spacer. BIKE RIDES FINE WTH? I'm gonna hafta take it to my dude and pay him to take EVERYTHING apart. I'll bet that'll reveal what's wrong. More to come tomorrow. Toodles.
