Another popular upgrade is a24/24or26/26 carb.Replacement pistons can be purchasedhere.Replacement rings can be purchasedhere.Replacement gasket can be purchasedhere.***PLEASE NOTE***Performance upgrades are considered racing parts and are not covered by warranty. There are too many variables involved with user-installed parts, and pushing the limits of your engine tends to wear parts faster. Use at your own risk!This performance cylinder kit was designed to allow the best cooling characteristics possible. In order to do so, the manufacturer has created a specific layout of the cooling fins. On some applications, the cooling fins at the base of the cylinder come in contact with the flywheel. When this occurs, the fins must be ground off to allow clearance. Removing these fins will not hinder the cooling abilities of the cylinder nor will they subject the cylinder to premature failure. A simple grinding bit will work well for removal.Caution! When removing excess material, be very cautious. Any damage or modification to the cylinder is the sole responsibility of you, the owner.Not legal for use in California on pollution controlled vehicles. Check local laws before installing.This product is not intended for use on public roads or land.
