hello

 

I need some piston options for my vespa gs150 cylinder because is oval and need more than 57.8mm piston to do right correction.

 

i see kawasaki kr150 as a option...

Wiseco 339M05800 is a great 58,0mm piston for the GS150, but it has a 14mm wristpin and needs to be reworked to fit the original 15mm wristpin. The Wiseco has 1,2mm less compression height, improving port timing, but requires a cylinderhead different to the original one.

thank you

 

how convert to 14mm pin?

 

i was thinking on this
