Polini Cast Iron, very nice cilinder to tune.

Malossi sport's flow isn't as good as the Polini cast iron 70cc imo.

 

[XarsioN]

Thank you for the answer....!

But i Can't tune a cylinder =D

maybe I should by a corsa, allready tuned iron-kit.....what do you think, will it fit good with my exhaust (touring)?

 

[Aidix]

None of those cylinders will perform well with a Leovince Touring. Simply becuase it's a very bad exhaust for 70cc. In fact the faster timing of the Corsa may even result in less performance. You won't gain any top speed, but will notice an increase in torque.

If you really want a huge performance increase you should also invest in a new exhaust. If you simply want some better everyday driveability then any of those standard 70cc kits will do.

hm....ok

but wich should I go with then??? Yasuni R/Z for example to an Polini sport?

 

[Aidix]

Yasuni R would be great! That's probably your best bet. Yas. R with the Corsa is nice, but the MHR-Rep would be even nicer.
It all depends on how much you want to spend. The MHR-Rep for speedfight LC is a great looking cylinder and it performs rather good.

 

[XarsioN]

Ok...

Heh, it's my father who bought the parts...

hm...he just bought the touring, I'm going to tell him that Yasuni R for exemple is better....

It's for his dad's PGO ( Minarelli Engine )

is it the minarelli engine with vertical of horizontal mounted cilinder ?

 

[XarsioN]

Hm..ok..I talked to my dad, he think's the exhaust is expensive

I'm looking around for one now on the market...I maybe buy one polini for race of my friend....

But he asking you: will the polini sport 70cc perform the same with orginal exhaust and toruing, or is touring a little bit better??

 

[Opzorp]

Polini 4 race is also a good choice

 

[XarsioN]

and a soundy choice

 

[XarsioN]

heh, I'm changed my fathers mind =)

He is going to but when 50cc.org (and when he gots moor money)

Polini sport 70cc

Yasuni R (from a dude from this forum)

[Spy 70cc]

[XarsioN]
