Hi. I have a couple of questions for you folks. I have a small dirt
bike for my kids. It is a Baha brand, with plastic fenders. The
muffler cover broke into a couple of pieces in the cold winter. In a
boat, I would probably rough it up real good and use epoxy and a layer
of very thin, transparent, fiberglass cloth to make the repair. Epoxy
does not necessarily "stick" to plastic, but I have had good success
using a saw blade to really rough up the surfaces, sometimes a blade
edge to even create negative grooves to create a mechanical bond, hope
that makes sense. I have enough experience with these types of
materials, I could make it strong and even somewhat invisible, no
doubt.

I don't know exactly what material these are, is there a better way to
repair them? An if I do, would this type of plastic repair and it was
stable, would you think my kids would be able to race in organized
events, or tracks? If not I need to start to check into replacement
parts, but being a cheap brand, I wonder how hard they would be to
replace. I guess that's a question too, in case anyone has experience
getting parts for a Baha, purchased at an auto parts store;)

Thanks, Scotty

Check some of the "universal" plastics from Maier and the like.
Look at motosport.com and rockymountainatv.com for starters.
Repairs will only last for a brief while at best.  Fenders are
cheap.

   Yeah, and if you *must* repair the original (didn't you say it was
a "muffler cover?"), you might consider using thin metal on the back
side, with small nuts and bolts strategically placed through the two
pieces to hold them together (if possible). This could ensure
relatively great strength, but may not address the cosmetic side of
things.

 I would cut a small piece of aluminum sheeting to span both sides of
the break (placed behind the plastic), and then pop rivet them
together using at least three rivets on each side of the break.

 This worked very  well on my Husky's front fender, and on a lot of
side covers in the past.
