Can Am Defender 1000 TAPP Primary Clutch Kit by EVP.MOde

DESCRIPTION

NEW EVP TAPP CLUTCH UPDATES (2024):
Don't think a TAPP clutch can be any smoother and more responsive than it already is? Think again. The all-new Roller Spider design for TAPP Primary Clutches replaces the original button spider assembly for instant power delivery due to the reduction in friction between the spider and movable sheave. This results in even better belt grip than before, lower belt temps, better belt life, and buttery smooth engagement that's guaranteed to keep your car dialed in any riding condition. The patent-pending TAPP Roller Primary Clutch is the next revolution in clutching technology.

UPDATED FEATURES:

• ROLLER SPIDER DESIGN: creates less friction in the movable sheave compared to button spiders for a much more responsive setup
• CENTER BEARING: NEW black nitrate coating (black finish) adds an extra layer of hardness, prevents rust corrosion, and reduces friction for even smoother clutch operation
• LARGER ROLLER: roller size has been increased from 2mm to 3mm, making a huge difference in longevity of the clutch bearing particularly under high horsepower and harsh conditions
• POST: updated with additional material and new heat-treating process, allowing the clutch to be over-torqued from factory specs by preventing the clutch from slipping on the shaft (necessary for high-horsepower builds and/or drag racing setups)
• MOVEABLE SHEAVE: added material with the new roller spider design, reinforcing the clutch towers for greater load-bearing capabilities
• CLUTCH COVER: the billet aluminum clutch cover now features larger "windows" to allow additional weight without having to modify the clutch cover

EVP has developed, tested, and fine-tuned the perfect TAPP primary clutch calibration for Can Am Defenders that delivers bolt-on performance and responsiveness you will feel at first pull. Faster acceleration, higher top speeds, amazing zero to 40 mph pulls holding higher RPMs over stock, and virtually no clutch chatter — all standard-issue upgrades of an EVP.MOde Spec TAPP Primary Clutch for Can Am Defenders.

Calibrated for use with the bone-stock Defender secondary clutch, additional TAPP Clutch features include cooler operating temperatures to extend clutch and belt life, responsive power put down via excellent belt grip, and easily adjustable weight profiles that allow your TAPP to evolve as your Defender's power level evolves. From trail riding and navigating technical terrain to hauling, plowing or casually cruising, you're guaranteed to feel the difference an EVP.MOde Spec TAPP primary clutch makes.

ADDITIONAL TAPP CLUTCH FEATURES:

• DURABLE PERFORMANCE: TAPP clutches are built from billet aluminum and other high-tech materials that can withstand extreme heat and extend clutch life, so you can spend more time riding and less time in the shop. EVP has used TAPP clutches on our all-out drag race Can Am X3 and Polaris XPT vehicles with very high engagement launches without failure. The OEM primary clutch is reliable up to about 300 hp, but an EVP Spec TAPP primary can easily handle anything from 200-500+ hp and all terrain and riding styles - drag race, duning, trail riding, rock crawling, short course and desert racing - all with the unrivaled quality, durability and performance expected out of a TAPP Clutch.
• ADJUSTABLE & VERSATILE: TAPP clutches are a game-changer when it comes to tuning and adjustability, allowing your clutch to easily evolve as your UTV's power level evolves. The two-sided ramps are swapped in minutes with just an Allen wrench. The clickers are adjusted externally, which can raise or lower the entire shift pattern easily. The roller arms allow mass to be added or removed by removing the clutch cover, and there are a variety of TAPP and EVP primary springs available for fine-tuning. Lastly, the TAPP clutch is also extremely forgiving, allowing a wide variety of helix angles to work with a given primary clutch calibration.
• COOLER TEMPS: TAPP primary clutches run cooler than any clutch on the market. High-tech materials, extensive venting for optimum airflow, and cooler belt temperatures thanks to the multi-angle curved sheaves all contribute to extending belt and overall clutch life‚Äîeven under the most demanding abuse.
• INSTANT THROTTLE RESPONSE: TAPP primary clutches are intended for customers that demand responsiveness and durability from their CVT drive system whether their UTV is relatively stock or all-out big turbo drag race trim. The centralized mass and lightweight, low-inertia design coupled with multi-angled curved sheaves and custom ramp angles deliver unbeatable belt grip, instantaneous throttle response and surefire power to the ground.
• SMOOTH, QUIET OPERATION: The arms don't 'swing out' like a traditional flyweight but instead ride on a ramp system, which allows the clutch to be remarkably smooth and perform with minimal vibration. You will feel and hear the difference.

CALIBRATION GUIDE

There are 4 main adjustable components in an EVP Spec TAPP Clutch, these are:

Ramp Profile - Your TAPP clutch comes with a set of pre-chosen ramps that have been tested in many scenarios and have been deemed to be the most generic in most situations. Changing the angle or profile of the ramp will have many effects on the shift profile. This should only be done by an experienced tuner; you will likely not need to change this.

Ramp Angle - The ramp angle in your TAPP Clutch is adjustable from the outside via the use of the Quick Shift Bolts. As with other clicker style clutches, the higher the number, the higher the RPM. This will mainly affect the full shift speed but also affects the engagement and low speed slightly. IMPORTANT - Always adjust the ramp angle in pairs across from each other. If you do not, the clutch will be out of balance.

Roller Size - Your clutch was shipped with a predetermined roller size for your application. There are 3 sizes of rollers available: standard, 1mm oversize, and 2mm oversize. Bigger rollers make the low end "quicker RPM's" but shift out quicker and lower the full shift RPM. Smaller rollers make the engine slower shift and raise the full shift RPM. This has to do with the angle of the arms combined with the weight difference of the rollers. IMPORTANT - As with the ramp angle, roller size must be done in pairs across from each other. Failure to do so will result in an imbalance of the clutch and possibly failure.

Weight Adjustment - The weight in the arms can be adjusted in two ways: set screws in the arms, and washers on the roller thru bolt. As with all other clutches, add weight to lower RPM, remove weight to raise RPM. Set screws in the arms affect the low-speed shift points more than the high speed and will reduce the max RPM, and weight on the roller bolt acts like tip weight in a conventional clutch affecting the high speed more than any other part of the curve. Adjust this as needed for your application. IMPORTANT - As with all other adjustments, do this evenly and only in pairs across from each other, failure to do so will result in an imbalance of the clutch and possible failure.
