Engine bogging and not performing after loaded hill run. Changed to Yellow Torque Spring and found better performance and acceleration with no bogging. Engine not coasting along as much even decelerating with no throttle down hill. Also less top speed on flat. Belt feels like jumpy outside of rear pulley starting off like strong spring always pushing it out the top.
Changed to White Torque Spring and all is good. Engine will coast on flat better now and a higher for longer top speed (3-12km/h
)Not jumpy to start and also changed two clutch springs to yellow (1.5K ?)
