[roll on 3]

Found this piston for tecate big bore not sure if its for 3 or 4 Wiseco 73.95 mm has 8005 stamped and 3551J on piston. original box
not available. will try post pics soon. problem is its taller then stock piston from the pin up. May use a spacer plate ?
also it does have an oval hole on intake side unlike the jet ski piston.

Well only thing I have found is that the 92-2001 kx 250 has the same oval intake port as this piston couldn't find 73.95mm though
to match numbers. and the sides are not cut in same.:confused:

Maybe try finding an engine builder that specializes in t4s and see if they recognize the numbers?
