Ciao piston 64cc recommendations

I've got a 1977 Ciao with a scratched up piston and cylinder. Looking to get a upgrade 64cc kit from Treatland. Anyone have any recommendations or experiences? Malossi, polini, Olympia? Not looking to mod/port the the engine. Just looking to install and ride.

Re: Ciao piston 64cc recommendations

I got a DR kit for mine. Comes with a head too. Bolted it on with the stock pipe and gained 8mph. It's 125.00 so very affordable compared to the malossi,

Another good point is it's cast iron with a 2 ring set up so very forgiving to newb mistakes.

Re: Ciao piston 64cc recommendations

Dr kit is my fave too! Just be sure to upjet and do a leak down test once installed!

That is more than a scratch bro!!. I would do a full rebuild. Not worth spending the cash on a kit and not doing bearings and seals

Re: Ciao piston 64cc recommendations

Yeah I you are probably right. Its a nice bike and I've put a lot into it. I haven't done a full engine rebuild yet, but I'm confident I can take it apart and put it back together its the identifying problems, correct parts and figuring out the timing is where I'm lacking skills.

What causes a piston to chunk out like this? Running it with no oil?

Air leaks. Leaky decomp, head leak seal leak or base gasket leak. Expands piston the soft seized. Could be lots of other reasons too, but usually air leaks.

If you don’t rebuild the bottom end I would a get a seal for it. Easy to pop out the old one and press a new one in. I can’t remember the size but I think 1/2” pvc pipe works great as a seal press for vespa. (edited)

Good ole Can't Roff is still perpetuating this myth lol. My ciao does 45 mph and literally picks the front end up in corners.

In your case, go Olympia.

Re: Ciao piston 64cc recommendations

Olympia. I've done two kits . I'm no mechanic, but if you follow instructions. Download manuals , be patient ,you'll get it right the first time. 8)

Re: Ciao piston 64cc recommendations

Even if I wasn't going to case match I would do a Mallossi instead of the Olympia, quality is sooooo much better.

Re: Ciao piston 64cc recommendations

These are very easy motors to rebuild, definitely worth doing if its a bike you are going to keep around.

Re: Ciao piston 64cc recommendations

vespa is definitely one of the hardest for cross compatibility, with the case induction and 3 stud pattern each manufacturer got pretty creative with piston ports and boosts that don't come close to lining up between brands. You can't really just replace a piston, do a whole kit

Sweet bike

Re: Ciao piston 64cc recommendations

Ok I've got it all apart and going to rebuild it. Just checking I want the 12 pin version (12mm) not the 10 pin.

Re: Ciao piston 64cc recommendations

Ok I'm going with the 64cc Olympia. Can I use my stock Ciao head or do I need to buy a new head cylinder with the kit?

Re: Ciao piston 64cc recommendations

I would buy the matching head. Try to get one that has the Decomp valve installed. If your going with the olympia 43 12 pin, it comes with a matching head

You should replace the crank while it's all out, tbh. The brass bushings in these do not respond well to higher power and especially not well to RPM's

Re: Ciao piston 64cc recommendations

Also Joe, not that it matters. The kit comes without instructions. As a rookie I just read old threads , to make sure the arrow on the piston as a point downward to exhaust. Have fun.

Re: Ciao piston 64cc recommendations

I see treatland has a few 12 pin cranks. Got a recommendation?

For standard builds, these are great .

Re: Ciao piston 64cc recommendations

ok it in the basket too. dose it matter the kit comes with a 12mm pin and the crank comes with a needle bearing?

Re: Ciao piston 64cc recommendations

You want the needle bearing and 12 mm pin. That is the point of replacing the crank. The brass bushing on the old crank is inferior to the roller bearing crank that you're upgrading to. (edited)

Re: Ciao piston 64cc recommendations

ah ok I get it. Everything is ordered.
