header problem/leak?
« on: January 24, 2013, 11:38:17 PM »
ive been noticing specks of carbon(at least i think so) on my engine and splattered down towards the crankcase and when i looked at it further i noticed that it looks like specks are coming out of where the header is bolted in. also noticed a considerable gap and after trying to tighten the bolts it doesnt seem like it meets up flush like it seems like it should.

i attached a few pictures. am i missing a gasket? not  really sure about any of this. is it normal? why I am getting splattered specks of carbon on my engine every time i go for a ride?

thanks

That gold flange will not necessarily fit flush to the head, that's ok.  There's a ridge on its edge that presses the flared end of the header pipe to the head.  Also, the two bolts may not be equal distance out from the head.  Also ok.

With the engine running feel around where the pipe meets the head.  You can also hold a feather or piece of tissue paper.  If there is gas escaping you'll either feel it or see the feather/paper move.  If it is leaking, slowly and gently tighten the bolt nearest the leak.  If it feels like you're getting too tight, stop.  You don't want to strip it.  Order a new gasket, put it in, and slowly tighten both bolts equally until the leak stops.

I do notice a hissing noise when I shut the engine off, which i can say  almost definitely is coming from the flange. I did tighten it up just a minute ago...and it did seem to get rid of the hissing.
will a new gasket get rid of the carbon im seeing on my engine?
probably a dealer part too?

tightened up the bolts. started the engine.... stuck my hand down by the flange then revved the engine.... picture below is the result.

this can't be normal. is it?!
on the upside, no more hissing when i shut the bike off...but yeah. lots of carbon!

You've got an exhaust leak for sure.  As I said, you can try to tighten a bit more, do this with the engine running.  You only want to go tight enough to stop the leak, no tighter.  That's why you want it running, so you can feel for the leak as you tighten.  And if it feels too tight stop, don't strip things and cause yourself pain.

A new gasket would certainly help, and yes, it's a dealer part.  If it's been leaking for a while the leak may have erroded that spot on the gasket and no amount of tighening will fix it.  You may be able to order it straight from CMW, call and ask.  It's only a few dollars.  Get a couple.

awesome, thanks so much for your help. it's my first bike... a lot of common sense is all you need but I always like to ask first in case I'm missing something. Ill probably give my Charleston dealer a call tomorrow.
on a side note, I'm going to be ordering the D&D system pretty soon. I'm sure it just involves a simple gasket as well but I'm a big fan of the streamlined looked without the gold flange.

that's exactly what happened to mine when the gasket blew out. mine chomped out the whole lot.
when you order - buy 3 and hold 2 for reserves, i did and at least if i have a problem - i'm not tied up for days chasing a gasket

And use a peened over lock nut (not a nylon insert nut ) such as a stover type. This should be a permanent fix.

There are exhaust sealing silicones available at your local auto parts stores. Put some of that on your gaskets and the problem will be solved.

B- I'm in Charleston as well give LA Motors a call, last time I went up there they did not have the gaskets...  As mentioned earlier get a couple...  I'm out of the Country now, but when I get back maybe we can get together...

A little soap and water should take care of the hand issue.

My exhaust flange is actually bent, but it has kept a seal since day one. I'm afraid to disturb it, but I will have to soon, as I have a new down pipe waiting to self install itself. The pipe hasn't been doing a great job of self installing itself, so I have to help it I guess.
Does the gasket have to be RE factory issue of can I use a "cut your own" metallic header type gasket material?

Cut your own or get some of the fiber filled copper ones for aircraft. They work well, too. There's really no code to have to work from for gaskets.
