70cc kit

Hi have a Yamaha neos 50 and I want to put a 70 kit on it but don't know which one to go for any ideas ? Also what ratio of oil will I have to use thanks

respect the kit 50:1

hard life, will survive better on 40:1

need to increase the main jet, 2-3%

 

So it's better for me to go for the 50:1 option then

 

on a sport kit, where you let it warm up, exploit the power but don't thrash it, 50:1 is more than enough. The actual pumps on average throw out less than this.

you will need to blank the oil inlet to the carb, when pre-mixing in the tank.

 

i was thinking of getting this kit aswell for my mbk booster 50, will it run alright if i dont premix ? or will there not be enough oil in the carb mixture?
Cheers

 

Yes it run fine on the standard pump

 

nice one cheers
