Review on Wiseco PK1490 2 Stroke Motorcycle Top End by Mike Newbill

This is a great kit when converting a motorcycle. I was thinking of ordering just the piston but thought I should replace the wrist pin and then saw this kit which includes the piston, wrist pin, wrist pin bearing and top end gasket kit. The butt has a new gray coating on the skirts. I was surprised, but I had to drill two lubrication holes in the skirt. I noticed they were on an old piston so I followed the directions and it worked fine but I'm surprised it didn't have pre-drilled holes.
