OK I am gonna have a rant. Since I got the bike sorted and put back together, I know full well that I did everything up tight and so forth. Anyway I've had a clunk / rattle on bumps ever since I got it back on the road. Poking around I've found a couple of things that are loose. One spot I'd lost a bolt that attached the muffler to under the body. 'Til I could find a bolt that stayed I thought this was the leak. When I got the brake pads changed, the mechanic used the blue loctite stuff on the bolts to lock them in. Funnily enough the other end is threaded. Now I like to think I'd be told if I had threaded bolts holding my front brakes on. Dunno about you, I might be fussy. So once I found that, it took me a a few days to get some loctite. First up I swapped the brake caliper bolts on but it still rattled (and either way the upper bolt was threaded). After loctite and an appropriate curing period I took it out again this morning. Rattle. So anyway with the shits I popped Fritz on the stand and started banging the bike in various spots to see if I got a rattle. The tank seemed loose. In fact the front of it would lift approximately 8cm. The only thing stopping it moving more was that the bolt on the rear was tight. So I removed it and lifted the tank off. To my horror, neither bolt holding the fuel tank bracket to the frame was attached to the bracket. In fact the only reason they were still there was because there was no room for them to fall out. Now I know it's taken me weeks to find this fucking problem. I also know (I have pics) of the bike being reassembled, and in fact the one I last looked at shows the repainted tank just before it's attached. There's 2 bolts firmly in the bracket. All I got the bike shop to look at was the front end and forks to make sure they were aligned and correctly installed. I don't think that would require removal of the fuel tank, but even if it did there's no way it would require removal of the tank bracket.. Now I'm 99.9% sure that I *didn't* undo those bolts post photo - otherwise I'd have more photos. The tank went back on after the respray, and didn't come off at all. Even with the photo there's not enough evidence for me to get up the bike shop. Now I accept I may have stuffed up, don't get me wrong but I'd be pretty damned surprised given the info in front of me. Thankfully since I fixed that up, the rattle is completely gone. Felt good with the exhaust being the noisiest part of the bike again. Should I "provide feedback" (preferred) or just change shops (kneejerk reaction) ?
