Hi every one , I have picked up a std bore Honda line 300 kit to fit to my 1982 250r as you may imagine the piston/rings/ bore is more than ready for an over hall. I have been told a seadoo 580 piston will do the job , are these the same compression height as std ? If not other than a custom piston has any one got any ideas ? I'm on 76mm at present. Cheers guys .
