| i called wiseco and they said 52.00 piston kits is the biggest they go and never even been a consideration on going 52.50 even searched several big bore specialty sites and all the big bore kits come with a wiseco 52.00 mm kit if your knowledge of the 52.50 is only from the honda dealer who told you to sleave and plate toss it out the window you can keep looking but i dont think youll find a 52.50 |
