Very Good

It is the maximum size that can be used for J / R without a sleeve beating. The wiseco piston was used in order that a genuine OS piston might not come out with the engine OH this time. The cylinder is one sheet, a gasket is for J, and the piston top form is near 73 mm like genuine and four were equal when measure.

WAISEKO of 3.5-mm over was chosen as tuning of z1000j this time.
A piston is overly heavy first.
a zephyr 1100 -- it is heavy even if it compares that it is pure.
Moreover, it was with the rose also about accuracy and weight differences weighed about 2g from 1.
It may be what to say by the quality as a price.
coming to swerve -- it is .
I think that he would like to use per Cosworth, MTC, and JE next time.
