Premium Member jake Posted October 20, 2015 Premium Member Share Posted October 20, 2015 Torqued that bolt down to hard. 2015 FZ-07 2003 2014 GSXR 1000 Link to comment Share on other sites More sharing options...
Guest Ralph Posted October 20, 2015 Share Posted October 20, 2015 Why does it look scabby round the bottom of the bolt. Link to comment Share on other sites More sharing options...

Beemer Posted October 20, 2015 Share Posted October 20, 2015 Yup! I'd say repainted and bolt too tight. It will crack plastic every time. If I don't know the torque specs on something as a rule I only go 1/4 turn past finger tight and check it often. Some Loctite wouldn't hurt either.

pattybags Posted October 20, 2015 Author Share Posted October 20, 2015 Going to bring it in to the dealer this weekend. Should be under warranty. I only bought the bike a week ago. I would bring it today but it's nice out and I want to enjoy my last few days of riding. Link to comment Share on other sites More sharing options...
rick Posted October 20, 2015 Share Posted October 20, 2015 If you look closely at the plastic between the bottom of the pict and that bolt, there are raised bubbles in the surface of the plastic. Wonder if brake fluid was spilled on that plastic? Link to comment Share on other sites More sharing options...

Wonder if brake fluid was spilled on that plastic? It's hard to tell what's wrong with the paint from the picture but if you lose the plastic washer, that bolt will chew up the paint in that area too.

rick Posted October 20, 2015 Share Posted October 20, 2015 are those plastic bits actually painted or is the color in the plastic and the surface just glossy? But yeah, those are the only bolts holding those trim bits that have that clear plastic washer and they are sure easy to drop and play hide and seek.

Guest Ralph Posted October 20, 2015 Share Posted October 20, 2015 When you really look at it the whole panel looks strange it seems to have lots of round marks on it as though it as had a reaction to repainting. Link to comment Share on other sites More sharing options...

You know what Ralph, when I took the picture I didn't pay much attention to the round spots, I thought it was just dirty. But I just went and took another look, and those round spots are actually in the paint. Hmmm.... the plot thickens.... Link to comment Share on other sites More sharing options...

Wonder if brake fluid was spilled on that plastic? Rick you were spot on. Crack kept growing so I went to the dealer today. Brake line was loose and dripped brake fluid onto the panel and into the area with the bolt. Yamaha notified and approved work under warranty. Question though, is brake fluid that corrosive that it would eat through the panel and cause it to crack? Link to comment Share on other sites More sharing options...
bmwpowere36m3 Posted October 21, 2015 Share Posted October 21, 2015 No, crack is from over-tightening and/or lack of plastic washer under bolt. Link to comment Share on other sites More sharing options...
rick Posted October 21, 2015 Share Posted October 21, 2015 Brake fluid is really mean to paint and some plastics. All those blisters and that dissolved area right around the bolt are the result. It might have even dissolved the plastic washer that's suppose to be under the head of that cap screw. I guess it's possible that the brake fluid caused the plastic to swell or soften and Vibration caused it to crack. That's kinda reaching, but I'd like to think it wasn't from someone going simian on that little screw and way over-tightened it. It's just a pice of trim after all. Yer never gonna know what the order of events was. Have a close look at all painted surfaces in harm's way under that fitting andget anything ugly replaced Link to comment Share on other sites More sharing options...
Cruizin Posted October 21, 2015 Share Posted October 21, 2015 I knew a guy who smudged some brake fluid on the hood of his Chevelle once, liked the way it looked and buffed his entire car with it Yamaha MT-10 ForumYamaha Tracer 900 Forum Yamaha Ténéré 700 Forum Link to comment Share on other sites More sharing options...
rick Posted October 22, 2015 Share Posted October 22, 2015 I knew a guy who smudged some brake fluid on the hood of his Chevelle once, liked the way it looked and buffed his entire car with itI don't go near the brake master or clutch (if there is one) on a bike w/o covering the tank, instruments, windscreen and anything that could get dripped/splashed with that stuff. And then, in case all those unfolded plastic garbage bags aren't enough, I'll have a bucket of water and sponge at the ready. I think if i spilled brake fluid on a 70s vintage Chevelle SS, I might just get a bit sick. Link to comment Share on other sites More sharing options...
gregjet Posted October 25, 2015 Share Posted October 25, 2015 Brake fluid is a somewhat unpleasant chemical for a host of plastics ( including paint most of which are gonna be plastics). Even if it dosent dissolve it can change the nature ( I'll leave the word at that) of the plastic and change it. Including from malleable to brittle. As a rule brake fluid and just about anything don't mix ( DOT 5 and mineral oil fluids not included). Go forth and modify my son...go forth and modify...

rick Posted October 25, 2015 Share Posted October 25, 2015 unfortunately for brake components, DOTs 3,4 and 5.1 mix quite nicely with water. And that's why it's important to change them often. But they sure can ruin your day if spilled on the wrong spot. Link to comment Share on other sites More sharing options...
gregjet Posted October 26, 2015 Share Posted October 26, 2015 I was referring to their mixing being disadvantageous, rather than their actual miscibility... Go forth and modify my son...go forth and modify... Link to comment Share on other sites More sharing options...
