Vertex piston you buy from KTM?
A question for the professional techs in this group: A while back I talked to Wiseco at a trade show and they ended up sending me a brand new top end kit for my KTM 250 for free. All gaskets were included, but the base gasket looked cheap and I wanted to match the OEM thickness anyway. I headed to the KTM shop for a gasket along with my cylinder to get it honed. As the techs were doing the hone, the service manager basically shamed me for even trying a wiseco kit. I told him that I usually stick to OEM (Vertex) but I got this for free so I’m trying it. I also told him that I can get a Vertex piston that is not in an orange KTM box for about half the price, to which he replied “It isn’t the same piston. Those are junk”. On the way out the door, he advised me to clean the powervalve out, but KEEP THE DIAMOND GRIT IN THE BORE to help cut the rings in. The Wiseco instructions say the exact opposite so I removed the grit.
Is the Vertex piston you buy from KTM any different than the vertex piston you buy anywhere else?
Was he trying to sabotage me by telling me to leave the grit in the bore?
Thanks, and sorry for the long read.
