Q: I am trying to source a piston kit for a 1966 Suzuki T20 Hustler, No. 1 oversize. I am hoping you can steer me in the right direction.

A: From what little I can find out, the original pistons are unobtanium, but Suzuki GT380 pistons are available and fit, with one caution. You must use the GT380 piston pins, as they are 2mm shorter than the T20 pins and designed to fit the 380 pistons. Another option is the Suzuki RG250 MkIII pistons. Good luck with your rebuild. MC
