Where are the ring end gaps in those sleeves?
you want the end gap to run in the center of the finger port. it can be a bit off center , but not by much. you can have the end gap pins moved, so the end gap is always on the cyl wall ,adds cost. thats why it's beat to know ware the end gap runns before you start cuttin the cyl

Hi Fast Fred,
What is the different between build up port on the piston compare the original one. Thanks
Hi Fast Red,
What is the perfect dimension cut/sized (wide and long) of port suitable for Yamaha 50hp 3 strokes model 6h4?
Another question is why my engine always overheat during the race and damage my Wiseco piston (P4 size), is it cooling system fail or 2t add to fuel not enough?
Thanks sir
Post some photos of the piston from all sides..
Do you run extra piston to bore clearance to allow for the forged piston
