So is this a known problem?

While doing some work under the covers, I noticed some scratching on both sides of the fuel tank in the openings where the air from the radiators goes out the side grills. It was obviously coming from the screws that hold the grills on, in fact all 4 screws were polished shinny at the end of the screw. Seems like a bit of a clearance problem here, causing at the least vibration noise, and worse case a possible tank leak. I took the grill screws out, removed the clip nuts from the side panels and moved them to the grills, then put the screws back in the other way. I think this will result in more clearance (see attached pix). Anyone else notice this?

I've noticed some marks like that on my tank, but not quite as much as what you have. Are you the first owner? I wonder of those might have been removed and reinstalled at some time incorrectly? Regardless, you seem to have resolved the problem, which is a good thing!

No, I'm the second owner, but I can't imagine the original owner doing that. Maybe they were installed wrong at the factory. Someone go out and look in their grill and tell me if you see the screw heads or the screw ends.

Greetings Scurrie.

I have had the precise same problem as you have, right down to very similar severe scratching marks on my fuel tank. My service tech guy removed the screws and replaced them with either shorter screws or he changed them around. I forget exactly what he did. I can ask him for you if you like. You aren't alone on this issue. You do not want to hole your fuel tank. Apart from a potential fire risk, the tanks are very expensive to replace.

Cheers to all

Pretty clever on turning the screws around Scott! I also had the scratching on my tank and I am the only owner. My solution, which was posted once on the old list, was to simply flatten the screw tips and make sure that I did not have the longest screws in there. You want the shortest ones that will work.

I believe it was probably just careless assembly from the factory on some Bikes in using too long of a screw for that area.
