SOLD!!! AS OF 10/08/2023
This fits on any bottom end that uses 45mm stud spacing (any two piece 66cc/69cc "80cc") this will not work on one piece cylinders, high hole piston only.
Listing includes
49mm Cylinder
49mm Piston, w/ rings, circlips, needle bearing and wrist pin
Round head in the photo
Intake manifold, intake gasket, exhaust gasket and exhaust hardware
Head gasket and base gasket
Round head
Cylinder will be cleaned out before shipping, this includes deburring, case matching and cleaning out the overhang that is very common. It doesn't matter if you buy the cylinder from CDH as the "Iron Bore" or from Boygoesfast on eBay, heck you can even buy the engine, but you aren't going to avoid getting poor casting/overhang.
This is included in the price. The cylinder can be ported to a specific port timing of your choosing for $20 extra ($75 total)
$55 shipped (Mainland USA only)
$75 shipped if ported.
Note : I do run one of these 49mm top ends and I love it. If you plan on buying it to port it yourself, props to you, however make sure you understand port timing correctly before doing it.
