 1/ On the left is the standard Yamaha main jet square ring. It is a new part. On the right is the LiteTek part made from Viton 75. |
2/ Because of the very small size, the standard Yamaha part does not handle the heat involved in the manufacturing process very well. |
3/ The LiteTek part, being made from Viton, is far more heat resistant resulting in a better quality product. |
4/ This is where we fit the square ring. |
5/ Fit the square ring into the main jet recess. |
6/ The main jet screws down and compresses the square ring. |
