Ditto, your better off tuning a 50.
Here's the link to the gear up blog : http://www.pedparts.co.uk/blog/do-i-need-a-gearup-kit-with-a-malossi-or-polini-sport-70cc-kit
My 70cc streetrace has a 17.5 dellorto with an 85 jet and standard airbox (snorkel removed) and it breathes good and sounds nice. Your motor at...
With a stage 6 streetrace kit you don't really need a gear up kit cos it has a broad powerband which hols on tho the power at mutch higher revs...
First of all is the engine standard or modified? what carb is fitted and what size jets, air filter?
