Hello there, I'm just In the process of buying myself some goodies to build my engine, to a spec I'm happier with, as I'm planning (for those who know the program) a top gear style holiday with the bike, so want the extra oomph. I chose to ignore the idiotic comment on my last post and proceed anyway, so this is where I'm at ....
It's a morini 50cc engine
I have a 70cc kit which has had some further port polishing and a higher compression cylinder head
Polini variator along with a selection of rollers
Tecnigas silent exhaust
I've bored out the air filter housing, increased both the bore diameter of the air inlet hose and air box to carb hoses to 35mm
And I've got a 17.5 mm honed carburettor as apposed to the 12 / 12.5mm stock carb.
Would I still need to upjet the carb with all the additions, or will it handle it ok without?
Thanks

or 
main jet , also check your pilot jet as well and see what size it also is, I would think at least a 30-32 pilot would do it justice. 
..BAD TO THE BONE..
I've ordered a few I the sizes you mentioned, would there be any issues running the reed valve as standard?
