I had to have a set of 2 stroke cases welded at the bottom end just below the crank area. The welder ground down his welds on the mating surface a bit and I think he may have hit the non-welded area a bit leaving a slight depression. Im having the mating surfaces machined (taking down the welds to the original deck) but due to his grinding this may result in a very small gap between the 2 cases. These are match ground cases from factory with no center gasket but you do use a sealer.
So my question is how much pressure is there inside the cases in the crank area? Do you think sealer will hold or should I have the gap filled and then re-machine the mating surface?
I realize this is a judgment call but the gap is very very small and I just didn't know how much pressure there actually is in there. Im most likely going to fix it proper but I just figured id ask. thanks
