Belt Tension
1.
Remove the rubber chainguard cap from the right hand
shroud.
2.
Remove the rubber cap from the user left side.
3.
Use a 19mm socket to loosen the axle bolts on both sides
of the flywheel.
4.
Use a small crescent wrench to loosen the tension screw
lock nuts on both sides of the flywheel.
5.
Use a 3mm allen key to adjust the left and right tension-
screws by turning clockwise to tighten and counter-clock-
wise to loosen. Be sure to adjust the bolts evenly so that
the flywheel is not angled between the forks.
6.
Fine adjustment to the belt tension can be done using a
13mm open-ended wrench to loosen or tighten the ten-
sioner spring on the idler arm.
7.
Check belt tension using a sonic tension meter in the cen-
ter of the belt span. The belt should measure ~84 Hz.
8.
If you do not have a sonic tension meter, you can use a
tensioning app to measure the frequency.
NOTE: App settings are provided for convenience. Core
does not support third-party apps.
9.
Once proper tension has been achieved, re-tighten the
tension screw lock nuts.
