Oh dear-check that bolt

Well spotted - that would have been a heavy lump bumping up and down on the remaining fixings!

I guess you realise that your panel protector rubber is also missing in the pics? You should have two of these 22W-24181-00-00 wink

Brian an even a greater spot by yourself re the missing rubber's I guess these are the rascals http://www.boats.net/parts/search/Yamaha/Motorcycle/2005/TT-R250%20-%20TTR250T/EXHAUST/parts.html
Where do you reccomend obtaining replacements from?

Yes a big lump, I fired the bike up and checked for any leaks on the exhaust in case it had cracked etc but all looked fine thankfully.

For small parts like that it is just as well to buy from MotoWard or Fowlers mail order. Boats.net have great prices but orders usually take about 3 weeks (at least) to be shipped and get through Customs over here cry

The rear one is particularly worth fitting as most RH panels on trail-ridden TTRs I get are damaged or holed at that point. The rubber grommet thing gives the panel a fighting chance!

Ordered from Fowlers Friday 10am arrived Sat 9am, impressed.

Now fitted in time for tomorrows ride in the Lake district.

Thanks again Brian for spotting the missing grommets

Coincidentally, I was just near the end of a several hour ride when the muffler fell off! I had lost both bolts! I am really embarrassed to admit this, but I had been hearing an occasional clunk on bumps, but kept riding, anyway, since I had no tools with me. Fortunately, I had had a backpack, and a little water. After it got cool enough, I was able to secure it in in my backpack, and I rode back to my camp site "sans silencer". I purchased replacement bolts, but also used those 'high friction' washers to try and keep the bolts attached better. I have also purchase a front fender bag and another tool bag that fits over the headlamp cowling so I won't go off without at least some tools, again.

Hey Larry, I don't think I would have admitted to that one biggrin

Well hopefully everyone who has read my original thread with photos has now checked their exhaust bolts which I guess was my reason for posting it.

This must be a common problem.

I went for a long rocky ride yesterday and couldn't figure out what a slight rattle was at the back.
I had suspected my B and B stainless steel rack but it seemed secure.
The rack bolts thru the top muffler mount and has a special longer bolt which goes thru a standoff tube.

Everything was in place and seemingly tight but the muffler, when pushed, had vertical movement.

I guess the bolt hole in the muffler attachment tab is a fair bit bigger than the bolt diameter.
So slight movement is possible, leading to a vertical elongation of the hole, which can only get worse rapidly.
Lucky for me the bolt thread was well loctited, so I didn't lose the bolt.

I am suspicious of the longer bolt being part of the problem, allowing a slight flexing.

Tightening it really hard stopped it from being moved up and down by hand,
but I just know it will happen again!
