Guide to Z1 Gasket Set O-rings for a K4-K8
« on: January 27, 2014, 11:03:40 PM »
See the picture below.

Notes:
1. My number on top corresponds to the Vesrah guide, and below that is the parts diagram image name and the part number on that image.
2. I accidentally labeled the "Starter Motor Cover Gasket" as the "Breather Cover Gasket."  If you confuse these two gaskets, each one only fits in one place. 
3. I had already installed the valve stem seals so they are not present in the picture.  The valve stem seals look like #12, but they have a spring wrapped around one end.
4. There is debate on using the Vesrah #12.  Some say to use it, which requires enlarging the openings on the head gasket to accommodate the large o-rings.  Others, like the CycleX tech tips section and many on this forum, say to just use a bit of yamabond/gaskacinch/three bond #1104/hylomar around the pins where o-ring #12 would go, and use heavy duty engine studs.
5. Speaking of engine rubber, the nickle sized engine pucks will need to be purchased separately.  Because some of them have been made a bit thin recently, many on this forum recommend using a bit of yamabond/gaskacinch/three bond #1104/hylomar on the bottom side of the pucks when reassembling.
6. Vesrah #5 has a slightly different number on the parts diagram.  I was able to match these o-rings to the parts diagram o-rings by matching the dimensions.
7. The difference between Vesrah #4 and Vesrah #7 is miniscule.  Use a micrometer to tell the difference.
