Every time I take my 2009 VFR800 (about 85000km) for a ride, I immediately notice a rattling sensation from the back end. I get a bit of a knock when riding off over the curb, at lowish speed (70-90km/hr) on rougher tarmac I can feel an intermittent rattle/knock, yet on smooth tar seal or at higher speeds, the rattle disappears. I feel it most through the footpegs which I believe means the rattle is somewhere on the swingarm.
The chain has no tight spots and is well lubed and tensioned and runs completely smoothly when spun on the centrestand. I have checked and lubed the suspension bearings, all were in perfect greasy shape, and both sprockets are tight and free of slop.
The only thing I have found which might be the source is the rear calliper. There is a "normal" amount of freeplay on the sliding pins (and these have been cleaned and regreased recently) but I can feel some loose play in the bracket that the calliper bolts to. I can move this vertically and create a knock so I think I found my culprit but I am unsure what to do next. This is the plate that sits over the axle holder and connects to the swingarm with a torque arm. I am not concerned from a safety/function perspective but I would like to smooth out my rides.
Has anyone else had an issue with this part/area and can suggest the next step?
