1975 dt400 exhaust

Is the baffle removable on the 1975 dt400 exhaust system? cause mine has a ring of the baffle rattling around inside of it and i need to get in there to remove it and also to clean it a wee bit better thanks in advance

I would think it is removable. Most are. Sorry for the slow response we may be working on bikes.

If its the front pipe, you will need to cut it open, repair and repack, then weld back together.............not a nice job! If its the back box, then some OE parts have removable baffles, but if not then get a back box intended for MX bike and modify to fit.

Look at a microfiche picture on one of the parts websites and you'll see where it comes apart. Try Chaparral.

The silencer on my '79 YZ125 was doing the same thing. I cut one end of it off, pulled the loose baffle tube out, an then used a cutting torch to carefully burn off years of oil-soaked carbon buildup (without melting or cutting through the pipe). When it was clean, I had the baffle welded back in place, repacked it with new material, had the end I cut off welded back on, and then finally repainted it all. The bike finally ran great and the exhaust looked decent, if not factory.

Would I do it again? No, never. Just measure the stinger diameter and buy an aftermarket/universal fit silencer and figure out what it will take to get it mounted. It will be the same or less work to do that, and then you'll have something that's easily re-packable.

Are you talking about the turbine piece that's down inside the end 6 inches or so, or the actual baffles further in there? Both should be spot welded to the outer casing of the muffler, the only removable part on that exhaust is the very end "spout" looking piece (you might have a little tube attached to the spout piece).
