Hayabusa and sv piston size, cylinder and clearnace information

ahh, you should use new rings though with the new hone so they ware and mate together

ohh and just so every one knows

the SFV gladius now has alloy/plated cylinders with the same size pistons as the busa not sure what the piston to bore clearance is but i bet its about 0.020-0.030mm

may have to take you up on that for future work. how much you thinking?

about £60 + P&P

for 2 pistons 2 pins new the RRP is £119 each pistons and £13.97 each pin so rrp for both pistons and pins is £265.94

the pistons have 7k miles on them but will give you detailed pics when i get them (on the way from US of A)

if you hone the bore 0.030mm does this not give you a bigger end gap on the rings thus giveing you more blowbye on the piston,and does useing a lighter piston put the crank out of balance,"just a thought"

thus giveing you more blowbye on the piston as above

and does useing a lighter piston put the crank out of balance once again yes but not enough to warrant the £200+ to have the crank balanced if i changed the rods then yes i would need balancing
