Yx160 barrel on gpx/z155

[ioxide]

I have read that the cylinder and head from a yx160 will fit the z155 however I have noticed the yx160 is a 57mm stroke and the z155 a 55mm stroke, if I use the yx160 cylinder will it not result in a really low compression ratio?

My z155 cylinder measures 74.5mm from base to head, does anyone know the length of the yx160 barrel?

Any info would be a huge help

Hello, have you read this? There's no mention of stroke though.

150cc, 155cc and 160cc barrels are the same height and same bore (60mm), the stroke of the crankshaft is the difference in displacement (53mm, 55mm and 57mm respectively).
