Well, that was a bit of a shock after looking at my rear wheel yesterday. All 5 nuts were there when I replaced the sprocket carrier bearing (about 3 weeks ago) before going to the Knockhill BSB (2 weeks ago yesterday). When I got home I put the bike up on the ramp to take bits off for a clean only to find this,
Sprocket is only a few thousand mile old, but I'm replacing the chain and sprockets in August. The wheel is filthy, as is the sprocket. I've no-one else to blame but myself for loosing the nuts. I'm gonna stick some Nylok nuts before refitting the wheel.
Lucky they did not eat the swing arm as they came loose, or shot one of yer mates as they flew off at 300mph....
