This kit includes custom brand new Honda cylinder that has been steel sleeved with a 59mm piston. This is the ultimate upgrade for your bike! This kit does not require that you run an oil cooler but will definitely be an added benefit to your engine. All rings come pre-gapped and installed. You do not have to remove the piston from the cylinder to install because I have included a notch for the wrist pin for easy installation. 
 
Match this kit with my custom hand ported BIG VALVE race head to see massive gains in horse power! Second gear power wheelies in your near future!
