reed valve Vforce 4 R - Yamaha Yz 65 2018-2019
Product ID: MTV4R82B
Manufacturer: VFORCE
& bull; The design of the V-Force reed valves has a double surface area of the end part of the reed compared to a conventional design.
& bull; The advantages are:
1) The reed must flex for half & agrave; the distance of the reed of a traditional valve to obtain the same air flow
2) consequently & eacute; more easy to fully open and close the valve blades completely.
A slat never closes completely as it is always in motion. Consider that in an 8000 rpm engine the valve reeds open and close 133 times every second. But this fact highlights another advantage of the V-Force design. The lamellae, moving for a much shorter distance, generally last much longer; longer and wear less than the reeds of a traditional valve.
& bull; Rubber insert on the surface of the valve body where the upper edge of the reeds rests, to increase the life of the reeds.
& bull; New design of manifold, valve body and air guides specific for V-Force4 R.
