Essential Tools: Feeler Gauge

A simple, yet very important tool for measuring thickness, whether it is for clearance or gap between two points or parts. A feeler gauge with 25 blades in increments up to 1mm, is sufficient for most applications on a two stroke bike. 
Some applications that first comes to mind : 
  • Connecting rod lateral play
  • Piston ring gapping
  • Spark plug gapping
