*The pistons are not interchangeable as they are designed to fit the model year, displacement and cylinder head.Please make sure to check the type of big bore, displacement and model year before purchasing Piston Kit. *85 / 88cc pistons have the new 0.8-0.8-1.5 piston rings (75cc pistons have 1.0-1.0-2.0 piston rings).Please check the size before ordering for repair. *The pistons with the new 0.8-0.8-1.5 rings are marked with "R". Note: If the stainless steel head gasket is installed on the old cylinder, the valve and piston will interfere with each other and cause serious damage. Note: If a paper gasket is installed on a new (current) cylinder, the cam chain will not fit into the cam sprocket and cannot be installed.
This is a set of pistons and gaskets which are standard equipment for each big bore kit.Please use it for repair.The piston shape is designed to achieve the ideal compression ratio for the displacement and cylinder head combustion chamber shape.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
I bought this as Spare parts as I am currently running a 75. It's not likely to break, but just in case.
good point If your cylinder is large and sturdy, you can use it all the time by changing the piston.
Gasket and Piston ring are also available in Quantity.:It's easy because it's a Set.
The quality is good.
A bad point It's more expensive than buying the Bore Up Kit.
It is a personal opinion, but I think that 75cc is the best for Bore up of 50Base, so I want to keep riding and buy this as Spare parts. Because I want to avoid the thing that there is no Parts when I try to Overhaul it.View Detail
