nrg 70cc kit?

thanks adam its a liquid cooled cylinder the only markings i can find on the cylinder is that it has polini wrote in where the coolant goes and on the piston it also got polini on the inside and also 2950 and asso-w
how do i know if its an cast iron or aluminium kit
is a 77 main jet good for the set up in a 17.5 dellorto carb
im thinking it probably just a sport kit
do the polini reeds with the blue lettering make a difference

as long as both the engines are either air cooled or liquid cooled i think it will be fine im pretty sure they are air cooled on the nrg power hyper 1 anyway,i woul suggest rollers around the 5 gram mark or 4.5 gram the zx is a good pipe arart from the sleeve on the can that starts rotating after a while make sure all the nuts that hold it together are tight as they come loose too.does the barrel ahve any markings on it saying what range it is?ve-uk are the importer of these barrel kits.01159462991 is their number
