Dalton Quick adjust weights for Yamaha QAY

This method of adjustment allows for adding or subtracting mass from the main body of the flyweight without even removing the flyweight from the clutch. Makes for Quick and easy testing and tuning. This series of Quick Adjust uses our "DPYR" curvature that has been very popular on the four stroke models. QAY and DTYA are the same series and curve, etc. Originally, we only went up to QAY-62, and the turbos came along in the RX/Apex sled versions and the DTYA ( Dalton Turbo Yamaha Adjustable) came along. As you can see there are more options now.

Even within Yamaha factory flyweights there is great variance in grams and curvature for the same HP. With the curvature and location of mass used on our Dalton "Quick Adjust" it will most likely be different grams required that stock. Example : The QAY 54 set is often used on stock 3 cylinder Nitro/Viper type four stroke applications (based on your own chosen springs and helixes, etc). This is very different from stock.
