Scud, your exhaust gaskets should look like this:




Little rings. Usually with an asbestos like material in them.

Hoomgar,

hmmm..I had nothing like that on my exhaust pipes, mine were as mentioned only the outside pipes had half moons that kinda made a complete circle where the pipe went into the manifold and they were steel wtih no asbestos type coating on either of them...just plain steel.

Does Dennis Kirk have them do you know???

Thanks,

Scud

The gasket sits in the head and the end of the pipe is pressed into it by the clamps. It sounds like your describing your clamps. Look into the area where the pipe end fits into the head and you should see your exhaust gaskets in there. They can be worked out with a small screwdriver usually.

Dennis Kirk may, or Bike Bandit or just get them from mostly any motorcycle shop or the dealership. Also on eBay all the time.

yo dude!
you dont do a plug chop at various rpms, you do iy at various throttle openings, 1/8, 1/4, 1/2 and full.

and those tubes the needle slides in are called emulsion tubes or needle jets.

your petcock is vacuum activated, so follow the hose from your petcock. it plugs into one of your carbs (the small hose not the fuel line). make sure the other carbs have plugged nipples (nipple being the piece of metal the hose connects to) if your #1 cylinder doesnt have it pluggued, then theres your vacuum leak.

if your #1 goes to the petcock and your petcock doesnt flow on ON (ie you have to drive on prime or reserve or always flows on ON (ie even with the engine off), your petcock diaphragm might have a tear which would lean out the mix in that cylinder...

ill say more when i think of more

Scud,

You should have those four 1/2 moons and 4 gaskets. Mine were stuck in the manifold and I didn't get the old ones out (forgot to do it) and installed the new gaskets and then had to pull the pipes off again to take the old gaskets out. Get in there with a small pointy tool and get those old gaskets out.

[Scud]

Cracker, I looked into the exhaust ports and they must have fallen out or been removed prior because they are not in there...I went to my local Suzuki dealer and ordered four OEM gaskets at $4.29 ea. Should be here about the same time my new exhaust system arrives. There is a ton of carbon in each of my exhaust ports, id ther something I can do to remove all that carbon right now???

Gsbert, yea, your right and I understand now, it is the THROTTLE openings..gotcha!...also, thanks for the terminology..emulsion tubes. I will pull those and make sure all the holes are clear.

My petcock goes where you say it does and all the others are indeed plugged at the nipples. and you bet...when you think of more let me know, I really, really,really appreciate all the info.

[gsBert]

scud: so? does your petcock go to the #1 cylinder? did you check to make sure your petcock only flows in the PRIME position? and flows under vacuum in the on position?

if not then you have a busted petcock diaphragm and that's your vacuum leak at cyl 1...

unlikely but worth a shot

[Scud]

gsBert, The petcock hose goes to the number two carb, the others do not have any kind of nipple on them at all in the location where it attaches to the number two carb.

I did have the petcock apart last year and cleaned it out, the rubber diaphragm was fine at the time.

Thanks!

[Hoomgar]

No exhaust gaskets!?!?!?!
Cracks and holes in the pipes?

I'm putting money on 90%+ of your troubles being related
to your exhaust setup.

[Scud]

Well.....I sure hope so it is starting to get expensive!!

Scud

[Scud]

gsBert, one more thing..I have my tank off and gas is not flowing out the supply tube (tank is full), this tells me that the diaphragm is working right?

Scud

[gsBert]

not necessarily scud, suck on the vacuum hose, then it should flow in the on position. that tells you the diaphragm is working. dont worry, you shouldnt get any gas out of that tube...

but mostly yeah, unless it's been assembled wrong. as far as i know only yamahas left the factory that way (dual petcocks, one for each carb on their viragos)

did you get that exhaust on yet? my money is with hoomgar at this point...

[Hoomgar]

dont worry, you shouldnt get any gas out of that tube...

Unless the diaphragm is bad in which case you could get a mouth full! My petcock would have wet your whistle if you had done that to it last month and it also shut off when not under vacuum. You have been warned! 8O

[Scud]

I will forego the 'suck' test, I feel that the petcock is working ok, besides I acquired a taste for 89 octane about two years ago and have been off the stuff since then

My exhaust system will be here tomorrow according to UPS tracking info.

I ordered valve cover, breather, and exhaust gaskets, and the four half moons from my local dealer four days ago, said they would be here tomorrow at the latest....his track record with me has been off by a few days so we will see. :?

As soon as I recieve it all I will be installing...ahhh...this is like christmas only it costs more... :roll:

Scud

[KEITH KRAUSE]

I didn't go back to see what you've done recently, but since you have the valve cover off, have you checked the valve clearances? If so, describe how and at what cam lobe position you checked/adjusted them.
