those german pistons that shocky put up look good. has anyone use that brand before?

[shocky]

i think david blythe may have or has at least shown interest in the past

if your talking about wossner pistons ive just bought one for my ts1200 (IT 175 piston) and the quality looks superb

the cart racing guys at work have used them and recommend them (they rev to 12 / 14 000 rpm)

cheers
