  1. HEY ! looks to me that someone has incorrectly light'n the crankshaft on the assembly in the opening picture of the assembly.The counters can be drilled out but the featured above is weakened by what appears to be router grove a little to deep little to close to the crankshaft center line.It will break if so.

  2. Like the video once again,These engines are the easiest to assemble and reassemble without doubt.I'd planned to enhance the basic Stinger but have to pay for machining of the piece itself.I'd rather build a turbo charger out of a small billet of aluminium for it very little to it no less until I pick up some tools I'll have to be content…Boy Go Fast !

  3. What to do is what you need not do if you can't rely on the basics,These engines are tough enough to go 11.1 compression on 97 octane but not intended to run down the interstate. Granted machine shop high speed balancing the assembly is likely expensive if you can get it done so 1 or two ounces a distance from the crankshaft center can be done on a drill press rod and forged piston if you want to stand there throttle wide open awaiting detonation….

  4. eu tive uma idéia de otimizar esse motor,retirando todo o mecanismo(bobina) de geração de energia e subistituindo-o por uma bateria.Isso é possivel? 

  5. dude there was no sealant just a gasket and it was a bitch to split it apart.  with that sealant in u gonna sweat on yr next rebuild

  6. using a framing hammer is definitely not the best way to install main bearings, but hey, you have to work with what you have…
    I would use a press personally. Preferably one from Harbor freight for only $75…
