I have a 1976 Z900 A4. I have replaced the exhaust with a 4 into 4, Cleaned the carbs and installed Standard Jets.
A friend of mine was going to come around on Saturday to tune the Carbs using the gauges he uses on his Hodna, he has just told me that I need to reset the tappers before I tune the carbs?
Is this correct?
If it is correct is it Shims or tappets?

Thanks in advance.

They are shims, and yes you need to check those, also cam chain tension, engine timing, a whole service really with the carb balancing last.

Oh Bugger, I’ll have to get that done somewhere then as it is beyond me.

Thank you for replying.
