Dyna Muffler Help
06/10/09 at 13:36:45

OK, I got my brand new HD Dyna slip on muffler yesterday. I looked this afternoon and as I suspected my clamps and such on my 87 are rusted probably to the point of breaking off (that is the way it usually works). I sprayed them with some wd40 kind of stuff and I am sure I can break them off.

If I break the clamp bolt, I guess I can take some kind of grinder and get down there and get the clamp off. Will the muffler then slip off as it is supposed to do, or will it be grown together as well. Then what about the surface of the header pipe, will I be able to get that to seal or will I need to smooth that as well? I would love to start on this in the morning, I might even work tonight so I can.

I am not too worried about the mounting bolts breaking, I am sure they will, but I think I can just slide the old muffler off.

So, am I on the right track? Any suggestions? I thought about taking the header off at the engine but that may create more issues with sealing that back on.

Thanks

When I took mine apart ('08), there was a fibery kinda seal between the header pipe and the muffler. If yours came with that, it may have helped keep them from growing together. If not, you may have to use the grinder to get things apart, and some emory cloth or sandpaper to smooth the header pipe back down. As far as removing the header from the bike, I had to in order to get a good angle of attack on the screws that hold the factory heat sheild on (blankety blank phillips head! Angry

). To get the muffler to seal onto the header, I used the goop that everyone else recommended, and it seems to be working so far; of course I used the heavy duty u-bolt clamps too. I also haven't noticed a leak where the header goes into the block, but if it starts, it's easy to get to with a replacement gasket.

Good luck with yours! Wink

It fit's snug. I could slide the exhaust off the header by hand albeit it had to be a straight pull. The the goop sealed the two together into one unit.

I used the clamps as a "just in case". Besides, they were cheap.

OK the dyna is on!

It really wasn't too bad a job, maybe 2 hours total, including a trip to the mufler shop.

I did take the whole thing off at the engine, that did make it easier. As I predicted two of the three bolts broke off, but having it where I could get to it really made a difference. I took the muffler and the header to the muffler shop and got a piece of scrap from the barrell, welded it to the header, opened the muffler a tad and gave the man $5.

Once home it was no trouble to bolt everything back together. The sound is cool, there is alot of popping going on. I am sure I need to rejet now. I need to get a heat sheild back over the joint.

All in all not a bad couple of hours.

I probably still need to rejet, but there are other things that are more pressing right now.

I'm wondering if some of the popping I still get is due to a tiny leak somewhere. Regarding the jetting, one of the other folks added a Dyna muffler, and K&N cartridge filter, and got by on the stock jets. I'm considering switching the filter too, eventually. Really don't wanna tear off the carb to get to the jets!

Yawimp!
get a jet set from lancer.
Loosen the carb duct clamps or use a mirror.
remove bowl screws, they may need convincing with a small vice grip.
drop bowl.
use a short stubby flat blade screwdriver and remove the main.
replace as required.
pilot optional.
then replace bowl with allen socket head screws.

You can tell the wife it's difficult but not us, well at least half of us anyway.

I know, I know. And I don't have to worry about playing up the difficulty to the wife. Divorced years ago, that's why I can afford the bike! Cheesy

The rejet is one of the next mods on my list, along with fork brace. Vacation in a couple weeks is at the top of my budgetary requirements though. Yeehaw! Grin

I really think that about took care of my popping, the leaks were the main culprit. Don't tell Rocco, but the backfire is almost completely gone. I have a stock airbox and stock filter and stock jets as well.

That's why I'm not in a huge hurry to change mine. If yours works fine, I can live with mine for a while. Besides, I haven't noticed any bluing of the header (beyond what it was from the factory lean settings), so it must not be running any hotter than before. Undecided

Yeah, heat shields really make things look "finished". Of course you realize we all want to see pics now! Grin
