These are the cc I get when I calculate with a original storke of 57,8mm: 60mm cylinder with original crank: 163cc 60mm cylinder with 6mm stroker crank: 180cc
61mm cylinder with original crank: 168cc 61mm cylinder with 6mm stroker crank: 186cc
62mm cylinder with original crank: 174cc 62mm cylinder with 6mm stroker crank: 192cc
63mm cylinder with original crank: 180cc 63mm cylinder with 6mm stroker crank: 198cc
I also see in your profile that you already have a 60mm cylinder mounted. If you would put the 6mm stroker crank on your engine as it is you would get 180cc. And if you buy a 61mm kit it would only give you 6cc more, is it worth the money?

Was thinking the same thought the 61mm has less metal on the cylinder walls probably the 4mm and 60mm kit is my safest bet the 6mm is more for racing and may cause issues
