Throttle Cam System 2-Strokes (Includes CAM 100, 200, and 400)
The G2 Throttle Cam System can make your bike easier to ride in rough, technical conditions. By utilizing different cams on the throttle tube for different track or trail conditions, you will have increased control of
the power delivery, resulting in better control of your motorcycle and less wasted energy due to unwanted wheel spin or abrupt power delivery. |
|
The G2 Throttle Cam System kit comes with Cams 100, 200, and 400. The 200 and 400 cams allow a more precise control of throttle
opening during the 1/3 of throttle opening, but retain the same overall rotation to full throttle. |
| Cams 050 and 300 are available separately. Cam 050 also comes in the Quick-Turn kit. |
CAM 050 - (sold separately or in Quick-Turn kit)
8-10% FASTER throttle opening. Ideal for supermoto and highly recommended for
aggressive 250F riders on tacky or sandy tracks that allow full throttle use.
CAM 100 - use when conditions offer near perfect traction - same as stock profile.
CAM 200 - use for intermediate conditions or moderately technical trails.
8-10% slower throttle opening during the first 1/3 of throttle
opening, same overall rotation from closed to full throttle.
CAM 300 - (sold separately) use for moderately technical trails.
13-17% slower throttle opening during the first 1/3 of throttle opening,
same
overall rotation from closed to full throttle.
CAM 400 - use for slippery, technical, tight trail conditions.
15-20% slower throttle opening during the first 1/3 of throttle opening,
same overall
rotation from closed to full throttle. |

Product Description:
G2 Challenge: Improve control in changing conditions for moto and offroad.
G2 Solution: The Throttle Cam System.
The Throttle Cam System incorporates a non-linear ratio between hand throttle rotation and carburetor or throttle body opening. The "pulley";, or as we call it, "cam"; pulls the throttle cable
as the rider rotates the grip/tube. By altering the conventional, circular shaped cam, a vast improvement in control is achieved.
The Throttle Cam System has cam options with reduced radius for the first ½ of throttle rotation, which requires a slightly farther turn to achieve the same carburetor or throttle body
opening position as a stock throttle. This slightly longer pull makes a HUGE difference in rider control as the power is rolled on. The system comes with a "100CAM"; --- same as stock, "200CAM"; ---
starts out 10% smaller than stock and "400CAM"; --- starts out 20% smaller than stock. The radius of the 200CAM and 400CAM increases or "ramps up"; to stock size at ½ throttle to keep
overall rotation required to reach full throttle at or near stock rotation.
G2 Key Points:
 Machined from 6061 aluminum in the USA!
Self-lubricating Delrin bushings at each end of tube eliminate aluminum-to-aluminum contact and provide an ultra-smooth feel
Alternate cams to fine tune control sold separately
Fits inside the stock throttle housing to stock cables
Removable end cap for simple handguard installation
Installs in minutes!

| G2 Throttle Cam System Technical Information: |
We recommend that you ride and evaluate the TCS before competition to try the three cams and feel how each effects your control. For best results,
try on a track as similar as possible to your normal racing conditions.
Your Throttle Cam System includes three cams (CAM 100/200/400). The CAM 100 is similar to your stock cam. The CAM200 has a "cammed"; shape with a slightly smaller radius in the first 1/4
turn of the throttle. The CAM 400 has a more pronounced "cam"; shape with an even smaller radius for the first 1/4 turn of the throttle.
For best results, start with the CAM 400. This will show the maximum amount of control with the system. After a few laps, change to the CAM 100 (stock). Going back to the stock feel will
provide a point of reference and demonstrate the advantage of this system. Now try the CAM 200. For the remainder of your test session, switch cams several times to feel which cam works best
in different conditions. This is crucial to teach yourself which cam to Select for different conditions. |
1. Attach cam to tube with grip securely installed. It is recommended that grip glue is used and safety wire installed.
Allow time for glue to properly set per manufacturers recommendations.
CAM 100 - installation is same as stock.
2. With engine turned off, slide tube/cam onto handlebar and attach throttle housing. Tighten bolts on housing to manufacturers recommendation.
3. Insert throttle cable into throttle housing and attach barrel of inner throttle cable to cable "keyhole" on CAM 100 with the small top throttle housing cover removed. Next, install
cable pulley and top throttle housing cover per manufacturers recommendations.
4. Adjust throttle cable free play per manufacturers recommendation before operation.
CAM 200/400 - Installation instructions:
1. With engine turned off, slide tube/cam onto handlebar.
2. Insert throttle cable into top half of throttle housing (not attached to the handlebar).
3. Pull inner cable as far as possible and hold with thumb (see picture) - similar to technique used to attach throttle cable to carburetor slide.
4. Insert inner throttle cable end barrel into cable "keyhole" on CAM 200/400.
5. Attach throttle housing to handlebar, install cable pulley and top throttle housing cover per manufacturers recommendations.
6. Adjust throttle cable free play per manufacturers recommendation before operation.
