The part # is in my old post above.

Kawasaki 11060-1330

You can find them from several sources. 

I just found one on amazon.

https://www.amazon.com/CALTRIC-Exhaust-KAWASAKI-11060-1330-11009-1680/dp/B01DYR4UGA

.

That's a very good price on Amazon, especially with the free shipping.  Best price for orgininal Kawasaki part is https://www.partsfish.com for $12.51 each, shipping for quantity 2 is $5.00.

BTW, as suggested to me in another thread, you may find it easier to install the new gasket by using a thin coat of Permatex Ultra Copper RTV sealant on the outside before slipping it into place in the female side of the joint. Then put another thin layer on the inside, and slip (perhaps forcefully) the male portion (from the header) into place. It makes the process easier, avoids cracking the new seal, and provides some extra sealant capability. A rubber mallet may be handy - it helped in my case.

Once all in place, tighten the bejabbers out of everything and go to bed. By tomorrow, everything will have set up and you're ready to ride.

I ordered the Guzzi one from MG Cycle for $22 plus change and also ordered the Kawasaki compatible one from an Amazon seller for $10.  The Kawasaki one is slightly smaller. I'll try installing them this weekend.

Dimensions from digital caliper measurements. This is a low end caliper so measurements could be off plus these gaskets are not perfectly round.  I hope the Kawasaki one fits over the male header pipe.

Guzzi gasket
Length - 30.5 to 30.75 mm
Thickness - 3.1 mm
O.D. - 54.5 to 55.4 mm
I.D. - 48.7 to 49.3

Kawasaki gasket
Length - 29.1 to 29.3
Thickness - 3.15
O.D. - 54.5 to 54.95
I. D. - 48.3 to 48.8

The Guzzi gasket fits perfectly.  The Kawasaki one is slightly small.  I pushed it on partially and it started splitting.  It will probably work ok, but there may be some leakage. I don't think it's worth the difference in price.

Now I need a pipe expander so I can get the other pipe over the gasket.  Amazon has a medium one for 1.54" - 2.31" I.D. and a large one for 2.10" - 3.25" I.D.  The gasket I.D. is about 1.95 " and O.D. is about 2.2".  The pipe metal is a little springy, so I think the medium one may not push it out enough so that it does not spring back too small.  But the large one may be too tight a fit to get it started.

I, and others, didn't have a bit of trouble using the Kawasaki part number pieces.  Looking at those caliper measurements, they appear to be practically the same.

Were the parts MG Cycles sent you actually "Guzzi" or Piaggio branded parts?

One suggestion that I noted early in this thread, when you tighten the clamps down, be sure to tighten them well.  I used a 1/2 inch drive pull handle.  Don't break the clamp but I noticed that I could get a lot more tightening with the 1/2 drive tools compared to my little 3/8 tools.  Use the bike a few days and put it through a few heat cycles and then tighten the clamps again if they need it.

I never ever had another leak in 50,000+ miles.

I hope MG Cycle sent me the actual Guzzi part. It fits perfectly.

I ordered the other one from Amazon for $10 which claimed just to be compatible with the Kawasaki part number. So it may not be the actual Kawasaki part.  There are a numbe4 of websites that sell OEM Kawasaki parts. Those may be better places to order the gasket from. Look at my photo. It is too small and it split when I forced it.
