14. Use a 3mm allen key and a 13mm open-ended wrench to
remove the two (2) screws and nuts connecting the cross
brace to the front right fork. Repeat this step for the other
side.
15. Push the front of the cross brace away from right front fork
to create a gap then slide the old belt through the gap.
Slide the new belt through this same gap then follow the
directions in reverse to install the new belt.
16. BEFORE TIGHTENING THE AXLE BOLTS
: Use a 3mm allen
key to adjust the left and right tensionscrews by turning
clockwise to tighten and counter-clockwise to loosen. Be
sure to adjust the bolts evenly so that the flywheel is not
angled between the forks.
17. Fine adjustment to the belt tension can be done using a
13mm open-endedwrench to loosen or tighten the ten-
sioner spring on the idler arm.
18. Check belt tension using a sonic tension meter in the cen-
ter of the belt span. The belt should measure ~84 Hz.
19. 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.
20. Once proper tension has been achieved, re-tighten the
tension screw lock nuts.
