Yoshimura Stage one Camshafts Z900 Z1000 73-80 ST-L1

Type ST-1
MAX LIFT(mm) IN 9. 50mm / EX 9. 00mm
1mm DURATION(degree) IN 245 degree / EX 245 degree
Standard tappet clearance (mm) IN 0.20mm / EX 0.20  These cams will work with shim under or shim on top set ups .   As POP Yoshimura used to say, "Air-cooled large displacement vehicles need more power and less weight", this lightweight camshaft for the Z1/Z2 was made possible by modern technology.The large-diameter hollowing process, which requires a very high level of technology, has reduced the weight by about 20% (600g) in two pieces.Combined with the gyroscopic effect, the accelerator response is improved.Furthermore, by applying barrel polishing to the surface processing, we have succeeded in reducing friction loss and increasing durability.
