Description
14.5~25.2 grams Ski-doo TRA Adjustable Weights Pins, are internal threaded, allowing to use a combination of different size setscrews, changing to different weights.
These TRA Adjustable Weights Pins for Ski-Doo allow you to change engine speed at full throttle.
Rule of thumb; IF need more engine speed, THEN reduce pinweight. IF need less engine speed, THEN add pinweight. You add or subtract to the weight of the pin with the larger or smaller setscrews and-or tungsten steel inserts.
1.0 gram of weight equals approximately 200 rpms change.
0.5 gram of weight equals approximately 100 rpms change.
All testing is done at full throttle; what does the tachometer say?
Fits all Ski-Doo TRA clutches. Fits TRA 2,3,4,5,7. Sold as a set of three TRA Adjustable Weights Pins.
Ski-doo TRA pins with our own added tungsten rods.
