Triumph 650 OEM spring kit


This spring kit from Kibblewhite is an OEM replacement for Triumph 650 heads from 1963-1972. It includes 4 inner and outer chrome silicon springs, 4 heat treated steel retainers, and 4 heat treated steel basewashers. This kit is designed to use stock keepers and does not include keepers. It can also be used on all unit 650 heads provided the included taller basewashers are used. Seat pressure is 68# @ recommended installed height 1.245"-1.255". Maximum recommended valve lift is .350". These springs are much higher quality than the current UK production and would be great for use with 3134 or stock cams.
