Crankcase bolts are strengthened by running them through both cases and putting nuts on the ends. Bearings will be next. Three bolts will be run thru the entire crankcase to ensure vacuum integrity of the aggregate system. The polished aluminum is on the inside of the engine and not on the outside. This polishing may produce a smoother air flow, resulting in better power over all.

  • you never polish any part of the induction system, fuel puddles on smooth surfaces. Polishing hasn't been in fashion for decades because of this.

  • @galactophore I do whatever I want now. Polishing on my channel and when ever and where ever I say it is , is in Fashion now.

  • @DIOSpeedDemon my bad, i just thought you were trying to go fast. puddling fuel and being slow must be the new black.

    try check your weight and the air fuel mixture on the carb

  • mr vegitto ...i think it's lose compression change the piston ring and piston and then adjust your block on to 0.9mm

  • can someone help me with my problem? my honda dio lost its torque, i already buy new clutch lining, change my driving belt, also my spark plug, but still the problem exsist,

  • I'm building a simular engine as you :)

    But I see you have the same 'problem' as I have...

    You cut into the boltwelds... Doesn't it suck 'flase air' in?

    If it does it wil be a bitch to set-up and will never perform the way it should..
