    I placed a Malossi sport 70cc cylinder kit at my Gilera Storm, a Tecnigas Next-R pipe, a malossi air filter and I have problems with my Dellorto PHVA 17,5. It has stock 32 iddle jet and 53 main jet. Can anyone please tell me which jet set up should I use to make my scoot run properly?

    No. No one can tell you what jet size to fit. You have to buy a box of different sizes and work your way through our carb guide to work out what works best for your bike.

    dont even bother trying to use it whilst having such a low jet in mate, i got a gilera ice and piaggio typhoon with technigas next r and for me the ideal jet increase was somewhere between 4 and 7 sizes. thats just for the exhaust, i would say you would need atleast a 70 main jet dont worrry about idle jet. maybe start with a 80 main jet and test and work way down untill its perfect.


    or just read the carb guide :) haha


    remember its better to run it rich then to run it lean
