Just balancing out , carb wise,  an H1B 72. As I just did a top end and it was on the lift, I noticed a small leak at the bottom (big surprise?) of the right and center exhaust, (brand new Doremi) system. When first installed, new crush washer, tightened evenly on each side till 60"lbs reached. This performed several times after each ride. Left side fine, just center and right leaking a small amount.
    Could someone tell me which side of the crush washer goes against the cylinder, flat or rounder type side. I don't believe the bible tells you. Also, I have no idea which way I placed the left one, that is not leaking? Not touching it!!!!
    I believe when taking out the center and right the flat side was against the cylinder?
    Any help would be great, none of my other Kaws are leaking/ A good thing. By the way, all mating surfaces look good, no burrs, etc. Tks Robert

Robert: Just to make sure --- You are talking about the round copper coated exhaust gaskets that slide into the cylinder for each pipe, correct?

If so, it shouldn't make much difference which way you put them in.

That said - it DOES make a difference in how you install your 2-piece exhausts for your H1-B. Sometimes, you can end up with some "torque" (twist) that will prevent the pipes from sealing well at the cylinders.

This is what I do: I loosely mount all three mufflers (at the rear footpegs and at the frame mounts) and also leave the screws very loose in the muffler "connectors" with the rubber inserts and then slide the exhaust pipe into the muffler connectors. Then I slide the exhaust gasket into the cylinder and put the exhaust pipe in there to keep the gasket in its place. Then I tighten the 2 nuts on the exhaust studs alternately as I continue to "wiggle" the exhaust pipes and the mufflers to make sure there is no "binding".

I think it is important to get the pipes to "seal" at the cylinders first, as I think the rubber seals in the muffler connectors have some "give" in them to help seal at that connection. Then I tighten the muffler mounts at the frame and then at the rear footpeg mounts.

Maybe try that method and see how it works.

thank you very much for the response. Out of 43 views, you were the only one that responded, Tks.'
   I will adhere to you instructions. I'm also going to buy a tube of heat resistant sealant, and add some on install. As you said and your probably right, sometimes a minor torque or bend will influence a connection/seal. I'll let you know. Thanks gain for your time. Robert
