well, one of my buddies decided to come over at 7:30 this morning to mark the trails since we got hammered on last night leaving a good 10 inches of powder. anyways, i noticed about an hour later my sled sounded really loud. i didnt think anything of it. it kept getting louder and louder. i looked at the muffler where it bends where it connects to the exhaust manifold. it had a crack about 2 inches long in it. i figured it would be fine until i could get home to weld it. anyways i kept riding and finally it became more noisey then ever. i now have a hole about 3 inches long and an inch wide. what could of caused this mayhem?

Yep you can weld it, on my old 02 mxz 800 I got a piece of steel from a old computer cass and welded it on. Now I cant weld worth a crap but when I was done it was the strongest part of the muffler.

Yes with a MIG no problem, a plane welder maybe to strong to hot, but the mig can do it.

Wow! A coathanger? I didn't know they made mufflers out of plastic these days!:huh::tongue:

Actually, I haven't heard that mentioned very often, but that was what I was taught way back when I was learning to weld - use a wire coathanger for mufflers. There must be something special about that low tech "rod." I know it has always worked for me with the gas welder.

As for a twenty something year old muffler, I don't know, but since they are as pricey as they are - if you can even find one that old, I think a MIG or gas effort would be worth the trouble.

I WONDER HOW MANY PEOPLE HAVEN'T SEEN A WIRE COATHANGER? THEY AREN'T USED THAT OFTEN ANYMORE.

stacks of them around the uniform lockers at work. talk about scary is many old race cars were built out of hangers :wink: . other than age the main cause would be from vibration or movement. that being said, are all the exhaust mounts there and in good shape?

I remember back when I was living at home I rode a 250 elan that had to see the welder every so often. On this sled the baffle kept breaking loose and rattling inside and kept cracking where the tube went into the canister. My dad cut the top off and pulled the broken baffle out and kept welding the cracks up . He also welded some more supports around the tube to help it from cracking. It didnt look to pretty but it worked .
Those one luggers sure had alot of viberation , but you could pound the crap out of them and still keep running, sure had a blast on that thing.
