HOW TO MEASURE CHAIN SIZE
Each of these components will be measured separately
- Pitch: The length measured from center of pin to center of pin. (P)
- Roller Diamete : The outside diameter of the roller. (D)
- Plate Height : The dimension from top of plate to bottom of plate.(H)
- Pin Diameter: The outside diameter of the pin.(F)
- Pin Length : From the outside of pin end to the other side of pin end. (A)
- Plate Thickness: Thickness of the plates from one flat side to the other side of the same plate. (T)
- Roller Width : The inside width of the inner side plates ( W)
- Factors to consider when choosing an ideal pitch of chain would include:
- 1. In-board or out-board drive sprocket configuration
- 2. Availability of engine sprockets, Final desired gearing
- 3. Set-up difficulities (length of chain measurements)
HOW TO MEASURE CHAIN SIZE
As a first step, we should define the components of roller chain
- Pin Link Plate : This is an outer plate on the pin link of roller chain.
- Roller Link Plate : This is an inner plate on the roller link of roller chain.
- Roller : This rotates on top of the bushing on the roller link.
- Pin : This is press fit into the pin link plate and bisects the bushings in the roller link.
- Bush : This is press fit into two roller link plates and is bisected by the pin in the pin link.
- What Size Chain Should I Buy ?
- Most go kart chains and mini bike chains have the chain size stamped directly on the chain links.
- #35, 40, 41, 420 and 50 chain are used on American Go Karts and Mini Bikes.
- An 11 or 12 tooth clutch sprocket usually indicates the use of 35 chain.
- 10 tooth clutch sprockets usually indicate the use of #40, 41 or 420 chain.

Needed a chain for a mini bike that was pieced together. The old chain had been spliced and put together with a few master links. Measured the old chain to the new one, popped out a link. Installed the master and good as new.
