1971 sl125 Honda big bore - 150cc help!

I'm planning on a sl125 hop up the around 150cc for an ahrma classic mx'er. Does anybody have the straight dope on how do this. I checked around about tha cb750 piston and 62mm sleeve idea but nobody has the details. Powroll is out of their 145 kits and ebay has 165 kit that requires case machining. Powroll strokers look great but are over the top of my budget. Thanks for the time and space. moto
