Clutch Sprocket Assembly
Primary Chain
The kick starter provides a means of starting the engine by manual power. When the pedal is moved in a downward stroke, ratchet teeth of the starter clutch gear and the starter clutch are engaged, transmitting force to the clutch sprocket, primary drive chain and to the engine sprocket.
On 1967 and later model XLH, an electric starter motor and Bendix type drive unit engage the ring gear on the clutch to crank the engine.

Standard rollers should measure .15625”-.15610“. 65)
Fit to shaft may not be determined by race size.
In order to fit 23 new std rollers in the race, it needs to be big enough to accept 23 rollers with out the rollers binding in the race.
When sized to the min. dia. that accepts 23 rollers with out bind, the shaft (.991” dia) will be will be about .002 running clearance.
This is because there is no roller cage. The rollers touch each other.
Because of the zero% roller to roller space trying to fit 23 o.s. rollers means the race needs to a lot bigger than the roller amount of roller o.s.
This results in a looser running fit than used in the standard rollers.
To use the os rollers and get a tighter fit than 23 standards, you can only use 22 o.s rollers.
Rigid hone / line lap race to take 23 standards.
Then let clearance be whatever it is.
