<br><font size=2 face="sans-serif"> Most of the time I have seen your
problem the actual fiber is not broken, but the resin is fractured. The
stinger is also a low stressed part. You do not need carbon fiber for the
repair, since you most likely have nothing finer than 3K plain weave, use
light weight thin fiberglass cloth.</font>
<br>
<br><font size=2 face="sans-serif">You will really want to clean this good.
Get a coffee can and fill it upwith 3-4 inches of acetone or methy-ethyl
ketone. Epoxy such as the one used on a high temp muffler is very chemical
resistant. Dip the entire back end up the muffler in the solvent and agitate
(in a vigorous circular motion-FZ). If the resin is fractured you
need to get the oil off of the fiber-so really get vigorous. This method
will leave no soap or other residue, and is far superior in cutting thru
the oil.</font>
<br>
<br><font size=2 face="sans-serif">Have one or two wraps of fine fiberlgass
cloth on the stinger and wet lay up with whatever epoxy you have. You might
want to pull a yarn from the weave and wrap the weave with hoop wraps to
keep it snug. The epoxy you have access to will not be as high temp
as the original, but it will work on the stinger.</font>
