New primary

[johan]

Do I need to balance the primary clutch. I bought a repair clutch unit, complete with all parts?

Yep those parts come unbalanced, unless you see some drill marks on back of fixed sheave.

Ok. So then I gonna balance it. I tested it on the machine and the machine was vibrating less then my old primary do so it can't be so much unbalanced

The new primary was only 0.2gram off . I could had run it without a problem. The second used Viper primary that has runned 4000km was 12gram off. Now i have one little little droll hole on the new sidewinder primary
