CJR ADJUSTABLE CAM GEAR

Add an upgraded HD cam sprocket to your setup with an adjustable +/- timing wheel. Advance the camshaft allows the valves to open and close sooner to help improve low end performance. While retarding the camshaft will allow the valves to open later in which helps increase high rpm overrev performance at a loss of low RPM torque.
WITH logo has 2 cam timing marks for MSX and 110 models
WITHOUT logo has 1 cam timing mark
Reference below for your model and cam timing default position

(ADAVANCING THE CAMSHAFT WOULD BE ROTATING TOWARDS 11:00 WHILE RETARDING THE CAM SPROCKET WOULD BE ROTATING TOWARDS 1:00)

In the dyno graph you can see on your 2022 Honda Grom we tested 3 settings total. The OEM location (Blue), advancing the camshaft (red) and retarding the camshaft (green).
- Advancing the camshaft just 2 hash marks resulted in +4% increase in low RPM torque (from stock) with a loss of -4% decrease in top end performance.
- Retarding the camshaft just 2 hash marks resulted in -4% loss in low RPM torque (from stock) with a gain of +4% increase in top end performance.
This resulted in an 8% shift in power with just a few degrees changed on the cam sprocket.

For CRF110 owners, a 10% shift in top end vs bottom end by solely advancing the cam sprocket. This is a change you can absolutely feel with vastly improved throttle response

Recommended to verify your sprocket degree before install by lining up the sprocket teeth with the inner pin that locks against the camshaft. Once lined up exactly, tighten and re-check they are matched.

Default location WITH CJR logo -
2014-2021 Grom/Monkey/Cub - Use MSX middle mark
2022 Grom/Monkey 5spd - Use middle 110i mark
CRF110 - Use middle 110i mark
CRF125F - Use middle 110i mark

Default Location WITHOUT logo -
2014-2021 Grom/Monkey = -1 from Centerline (1 line to the right = closer to 1 o’clock)
2019+ CRF110 = +2 from Centerline (2 lines to the left = closer to 11 o’clock)
2022 Honda Grom = +2.5 from Centerline (2 & 1/2 lines to the left = closer to 11 o’clock)

RECOMMENDED - Ensure to turn the engine over after a cam sprocket change, or check clearances to view the maximum degree that can be changed either direction.
