Okay once again i am stuck with a 1983 Yamaha 125 Tri-moto piston problem i finally went to a Wiseco dealer and found a STD piston which is 56.00mm. But when i got home i realized its for a DT engine even though i watched him look it up and get the part number. The piston does look different there are no side ports like the stock piston. Can anyone tell me if i can use this piston? or should i be taking it back?
Picture for reference
