Anti vibration dampers?

[joebloggs]

I think I understand why the early fairings are so difficult to find, like early Yamaha sports bikes the plastics pretty thin and brittle. My old EXUP's fairings would crack if you looked at them for long enough.

The 3CV's seem far tougher in comparison.

Has anybody used edging trim etc to replace the OE dampers, may sound like a dumb question but without the original I have nothing for comparison, and I'm concerned that using either too thick (stress) or thin (vibration) will cause me problems in the long run.

He Joe,
not sure I know what you mean by "edging" or "OE dampers". But yea, the fairings have been out of production for some time, and even if the bike has been garage kept, they are fairly fragile. I do think that the FJ's ABS plastic is generally thicker than other Yamahas of the same era. Classier I guess. :-)

Im just wrapping up a resto on an '98 1TX fairing. Take a look here for some pictures I took during the body work in case that is useful.  https://fjowners.com/index.php?topic=20477.msg209841#msg209841

Thanks for the reply, nice write up on your build.

By damper I meant foam or rubber strips Yamaha fitted to prevent vibration from destroying parts where they either touched or were mounted

I don't want to put my hard earned into paint only to have it ruined when cracks appear in the panels.

Your $6k quote reminds me the time I went to a local paint shop and was given a load of bull re what they would have to do to spray my bodywork, it was so off the scale I had to let him carry on to see where the conversation went. Talk about upselling, of course when I got home I logged on and gave him a great review, he wasn't impressed.

My intuition says that the fairing and the front fender endure the most vibration. On my 87, neither one have any vibration dampers on the mounting points. The fairing bolts to a sub frame for the headlight and instrument panel which is hard mounted to the frame. The front fender and chin scoop rides on metal spacers/grommets. I can't think of an effective way to rubber mount these. I don't think it'll be very effective to just put rubber strips behind the mounting holes. I think you'd need to enlarge the mounting holes and use rubber grommets to isolate the part (like is done on side covers). But I'm interested to see what you come up with.

The gas tank and side covers are rubber mounted. The tail section is partially rubber mounted iirc.

Yea, that $6k paint quote was a semi polite way for him to say "no thank you". As I just finished up painting, I can appreciate how much work it is. I'd probably charge the same if I were him.

Joe - several years ago I used some kind of edge trip to replace what I assumed were "dampers" between the inner fairing panels and the fairing. 

Probably found it at an auto parts or home repair place?
