How do you overhaul a moped engine Ciao?

When revising it is about broken wear parts are changed.

So it makes no sense to change everything from an old-timer engine, just because you think the new parts are of better quality. The original parts, which are still correct quality in contrast to today's retrofit sleeve

So when you revise, you should expand and disassemble the engine (but only if it is really necessary). Take pictures so you know where everything was.

You should check parts such as bearing, crankshaft, clutch, gear, piston, cylinder (so almost everything) (or let a mechanic check if you don't know) eg, the crankshaft should have an almost perfect round.

If the ball bearings are broken, I would recommend you brand ball bearings (SKF ball bearings) (SKF is the company).

There are various instructions on the Internet, but not on a special model!
