Tools to help you do the job right!

When working on your motor, use these handy items to pressure test your crankcase.  If your crankcase won’t hold pressure, it will seize your engine.  There is no other way to do this.  Also use these to keep foreign materials out when doing carburetor work.  Stud extensions allow you to set the engine on your bench without the rods hitting your bench.  They are threaded 8mm on one end and 10mm on the other to fit all engine studs.  Each plug and stud is anodized to enhance surface hardness and prevent corrosion.  4-step plug works on Mikuni carburetor flanges ranging from 26mm to 44mm.
