TERMINOLOGY
It's important to understand your Snypr weights and terminology. There are four quadrants in the Snypr weight. Each quadrant has a specific task. The table below shows each quadrant and shows the effect of each quadrant as speed increases. At 0% shift, your clutches are in the home position and in the lowest gear. At 100% shift, your clutches are fully shifted to the highest gear, Intimidator UTV Parts, Moab UTV Parts, Edge UTV Parts, Buffalo UTV Parts, Speed may increase above this point, but only from of an RPM exceeding the target peak power.
Image A
The HEEL - The force of the heel weight is applied instantly once the weight of the clutch overcomes the primary spring preload. This will gradually have moless spin as you approach maximum speed.
The TIP - The force of the tip weight will gradually increase as the speed increases.
The SNYPR HEEL - The Snyper heel weight will have little or no strength until the middle of the shift. After half a shift, the force will come on fairly quickly but will only be worth about half the weight in the Snyper tip.
The SNYPR TIP - The Snyper tip weight will have little or no strength until halfway. change. After half gear, the force will appear quickly and will have a similar effect as the weight in the tip.
ATTENTION OF YOUR TARGET RPM
Each engine has a maximum horsepower and a maximum torque. The graph below shows hypothetical maximum power and maximum torque. The goal of your clutch is to reach maximum torque very quickly, then build the revs up to maximum power while loading the motor. This will provide the fastest acceleration and best feel. The RPM should stabilize at your maximum power RPM.
Image B
Green line = Ideal Shift - The ideal shift will reach maximum torque rpm very quickly and then increase the maximum power rpm while loading the engine taking advantage of the torque while reaching maximum power. Maximum Power RPM should be achieved at 30-40% while shifting. If your machine shifts like this, you're set up perfectly.
Red line = RPM above target - RPM above target may feel very responsive, but will likely be much slower than an ideal gear change. Excessive revving is also harder on your engine. To bring your RPM back to maximum, add weight located centrally between the heel and toe.
Yellow line = Underthe target RPM - Being below the target RPM can seem lazy and unresponsive and will likely be much slower. Running below target can also increase fuel efficiency and, in some cases, reduce wear on engine components. To increase the RPM evenly throughout the shift, remove some weight from the center between the heel and toe.
TAKEOFF FROM STOP
Sliding and Belt wear often occurs during takeoff. otherwise known as Holeshot in the racing world. Takeoff corresponds to the first 30 to 40% of the shift. Under varying terrain conditions, the load on the belt during the section will significantly change due to resistance. Larger tires can also have a significant impact on takeoff load. The table below shows different scenarios. The description of the scenarios and the way ofadjust your weights are located below the table.
Image C
Green line = Ideal - No modification necessary
Red line = Overshoot - This condition must be resolved . Overshoot is caused by slipping or undertraveling when the clutch is first engaged. This is easy to resolve when using Snypr weights, as they generally have additional weight in the heel section compared to non-Snypr weights and a higher mass potential. To solve this condition, you can add UTV parts, UTV clutch parts, UTV bed accessories, Xinyang 500 UTV parts, add weight to the heel quadrant until it reacts like the green line .
Yellow line = Undershoot - This condition will be lazy and lack responsiveness and is easy to correct when using Snypr weights. Undershooting can also increase knock due to too slow an increase in rregime. To resolve this condition, xy 300 utv parts, realtreeXd utv 24v parts, move a little weight lower from the heel and insert it into the Snypr heel and tilt it evenly.
RPM FLIP OR RPM DROP
RPM should remain fairly constant on 4-stroke applications and a slight creep/rise is acceptable on 2-stroke since the pipe heats up and the RPM sweet spot shifts slightly. Below is a graph showing the RPM fluctuation and decline. Below the table is a description of the changes to be made to control each situation.
Image D
Green line = Stable - No changes necessary, this is ideal.
p>
Red line = RPM Fluep - On a 2-stroke this is ok but generally no more than 100-200 rpm above maximum power. On a 4-stroke, you want the revs to be stable. If you have too much diet creep, you can tame it by adding weight to the S tipnypr or adding weight to the tip. NOTE: Once the clutches are completely removed, the RPM will always increase 1 to 1 with MPH no matter what you do with your clutch weights. Make sure you are not trying to adjust your weights after a full shift.
Yellow line = RPM drop - RPM drop usually causes the vehicle to react, then disappear towards MPH superior. It can also increase engine knock by reducing engine speed. It's a simple solution, just remove a little weight from the Snypr locations and, if necessary, add a little to the heel and halfway to the toe.
