A complete top end kit for your '77 - '78 R100
Includes:
- 4 pushrod seals

- 2 head gaskets
- 2 valve cover gaskets
Stock and Siebenrock compression is 9.5:1 which can cause pinging with today's gas requiring either dual plugging or installing low compression base gaskets which would lower the compression from 9.5:1 to 8.8:1.
