Poling corsa 70cc kit, how many rings..?

Basically I'm looking to get one of these...

http://www.pedparts.co.uk/product/563/polini-corsa-70cc-cylinder-kit--piaggio-ac

I'm pretty sure I can see 2 in the picture but in this performance range all else I've seen is single rings and can't find anywhere online that tells me how many it actually has..

Little help please

Cheers

 

Yes the polini corsa has 2 rings its basicly a ported polini sport, if i was you i would buy a polini sport and raise the exhaust port 2.5mm then its more or less a corsa for a lot cheaper ! there is a guide on here how to do it i think

 

Hmm buying and installing a corsa may be a bit more expensive but it'll be much more reliable than a sport wi the exhaust ported by 2.5 tho right...

 

The polini corsa used to be a sport ported but now i think they made some more improvements to the corsa, a ported sport and a corsa will have nearly the same power and more or less the same reliability as they are near enough the same cylinder, but if your not confident enough to get a dremel out on a new polini sport then i dont blame you as you can easily turn it into a very expensive paper weight if you not careful lool

 

Haha ye we my dad owns a motorbike store and workshop chain so I have all the tools I need and any help I need I get for free so I'm not worried on labour I think I'll get the corsa because 50 quid is pocket change rather than a sport that I will most likely fuck up lol and end up spending double the amount. Lol
