I can pick these up at Red line but since I need to order some other stuff at Z1, was wondering if they offered a kit of these as well (or individually) but I can't seem to find at Z1...
Anyone know?
Thanks,

The problem with V&H (and other brand aftermarket pipes) is the lip on the header pipe that sits in the exhaust port is far thinner than on the factory pipes. Because of this, V&H and others provide slightly longer split collars - usually about 1/8" longer. If you use the factory collars with V&H pipes, the exhaust flange will bottom against the head before totally sealing the copper exhaust gasket into the port.
We can get them in, our price is around $4.60 each

Original Kawasaki pipes, the lip thickness is around 3mm. On V&H, they are around 1.5mm thick. I remember on some of the Kerker pipes them being decent thickness, but with Kerker now being owned by Supertrapp they changed the manufacturing processes.
If you ever run into a situation where the exhaust flange bottoms out on the head before totally sealing the exhaust gasket, there are thicker exhaust gaskets available.
www.z1enterprises.com/detail.aspx?ID=1602 These are about 2mm thicker than stock exhaust gaskets and they overcome the lip thinness issue. You don't want to routinely go with them unless you do have a problem - otherwise you can't get the nut started on the stud...

How much is lost in doubling up the gaskets if required?
No wonder this bike didn't have collars when I got it... Other than being a 30 year old POS that is... Really crappy after market pipes.

SKU: 92027-170 INSERT,EXHAUST PIPE
With this in mind, for those that have installed Kerker 4-1 Meg series pipes on their bikes, did you guys use the collars, thicker/double copper gaskets or something else?
Glad I looked into this, maybe just saved myself $42.:laugh:

Then throw into the mix my head (KZ head damn it :laugh:) has been shipped to Larry C so I can't even do any measurements. Poor OMR. :dry: :blink:
Same time, seems the OEM is what everyone had to use with the KZ1000 exhaust flanges. I'll probably just wait till I get the head back, installed and then test for measurements.
Thanks bud!
