Been coming out the factory like that 4-5 months
See the slots in the front
Saw three used M3W's outside Krazy Horse today. Early one had standard timing cover, no spacer. A second later model with spacing washers and a third with the JAP kit which does have three cooling slots. Had a good look at both models with standard covers and even felt along the horizontal ridges to see if there was a cooling slot but couldn't find one. Happy to be corrected though.
