The locking nuts on the valve gap adjustment bolt are not standard size and tend to slip, once they slip they tend to wear, making future adjustments tedious.
We offer replacement nuts which will fit all 5.5mm open wrenches perfectly in two styles, the familiar black and a slick stainless steel finish.
Sold in sets of 10
These fit Moki S180 through S300
