FITTING STEPS

This is a cinch: Cowls off, slacken exhaust and drop it off the cylinder stub, cylinder head off, double-nut the studs and remove them, slide off the cylinder, remove the gudgeon pin circlips, piston off. Clean up the casings and get ready to fit the new kit! Set up the cylinder with the provided gaskets to achieve 1.2-1.5mm squish, seal with Loctite or Threebond. There… sounds easy doesn’t it? For those needing a bit of guidance, a workshop manual and the Scooter Techniques DVDs can assist very well and can be bought online easily. Go on… give it a go.
