kangaroosa Posted October 5, 2007 Report Posted October 5, 2007 (edited) I'm running 83mm Hypertec Pistons in my 5K. They are in the catalogue to suit a Gemini. However they they did need to be machined (i think it was in the height) to make them fit. I purchased the bare 5K complete with pistons, rods and balanced bottom end for $500. The bloke i bought it off said thats a fair price because thats what it owed him. So i assume the pistons would have only been a couple of hundred at the most.
