A little leak up at the head to exhaust pipe join, or anywhere in the first few inches of pipe, will make them backfire.

Tried these guys.. They have always been good exhausts at a fair price.

I ended up welding a bombardier 400exhahst  onto it ... And then it still backfired , I discovered more holes up near the head, I'm going to use some high heat jb  weld to patch them

I havent had a lot of success with JB weld on exhaust , doesnt like the high heat, but it will hold for a while, if still having problems they make putty for exhaust, also doent hold up well, the constant jaring of the machine loosens it and it falls out. Not much help, but that is my expierience.

Thanks guys. So I scored another parts bike , possibly! 

And now that small hole in my exhaust blew apart into a huge 2inch hole right where the 2pipes join into one !!! So loud and backfires like crazy again . I hate riding it now because of the attention it draws...

 

But anyways, my current parts bike, has good pipes up to and past the join , I want to take it off and weld it on to replace the damaged portion.. 

But get this ! I tried to take the pipe off my good bike to replace it with the parts bike pipe, but The darn nuts on the header bolts are seized on there and basically morphed into the bolt. I already snapped one off trying to get it out ! I didn't want to proceed beyond that. Do you think I'm better off just cutting out a portion and welding it in 2 places instead of trying to replace the whole front part of the pipe ? Another thing I just thought of , was to weld a new bolt onto the old one , but it's a tight spot and I might not be able to actually do it (haven't really evaluated it yet )

Those bolts are sometimes hard to get off without breaking, i usually heat them cherry red and then srray with the water hose to cool them quickly and then douse with PB Blaster, it works most of the time.

Nut splitter is a good idea i have one and never think to try it, generally we dont think to try these things until we have already broken the nut off, but as a rule i always try something on muffler bolts that have never been removed 99 percent of the time they break.

And has it fixed the back-firing ?

Those nuts at the head join, some owners manuals say that as a matter of routine maintenance they should be loosened and re-tightened. It's only about once a year they say to do it.  It's probably in recognition of the fact those nuts seize.

Anti seize should work at temp. Graphite powder mixed with oil, or black grease, or copper based anti-seize are all pretty anti-seize and heat resistant.

I mostly just use a  black grease to lube those bolts. It's got Moly something..

It looks fairly complete, whenever i get a parts bike i look it over and say this is not bad and end up fixing it and turning it into a runner also, but thats what i like to do take junk and make it good again, i think its the challenge, not necessarily that i need another runner.

I think it's built into us to want to make something good..  It's what the religions are all about.. Explaining "creation", when we think of it as a verb. We're all the product/result of creation(v), and it's what keeps us alive and prosperous. It's an integral part of us this"creation" business..

Of course there's always someone (not you Gw) that takes things a bit too far and want's a bit too much, and  then the trouble starts..  haha

      Greetings, 
      Have a 88 LT80 that been sitting for a couple years. Bought a new piston, cylinder and head. Installed these, rolled it over and it quickly locks up.  Took carb apart. It was full of what appears to be 2 cycle oil. Cleaned it, but keeps locking up and 2 cycle oil continues to seap from exhaust port.  When i installed new cylinder, I noticed crankcase was full of oil.  I'm now wondering if that oil is what's getting sucked up into cylinder.  Should there be no oil in crankcase?  If that the case, how is crank and rod lubricated?  Sorry, never worked on a 2 stroke. Thanks!

      I see quite a few ads for that  Tribotex additive. It's kind of expensive, has anyone used it it their ATV or any other vehicle?

      How often do you change oil in front/rear diffrentials and gearbox?

      Hi guys. I have a problem where the quad will start and run well for about 5 minutes and then it dies. On inspection the airbox has oil in it (quite a lot). The oil is pumping through the cylinder head breather hose. This problem first happened suddenly. I have since done the top end including, piston, gaskets, rings and valves. I have also done the carb (not that I thought that this was the problem). The compression seems normal. The only thing that I can think of, is that I did not grind the valves well enough. Anyone experienced this? If so, how did you fix it? Any other thoughts?

      I’m looking for a top end kit for a Yamaha. I would like to see how well the engine runs before spending $6-$7 hundred on oem. Niche has complete kits from $1-$2 hundred.  Anyone have experience with Niche or similar Chinese companies?
