My opinion on low end 70cc cylinder kits.

When upgrading to 70cc is it a good option to use the standard 2stroke automixing tank/pump ? Or is it better on premix 2t oil? If yes what should be the ratio?

 

Run premixed, 2,5 %

 

I have used Airsal 70 Sport kits for last two scoots , they are the equal to the Polini Sport kit but aluminium rather than cast iron so way lighter and better cooling
