Speedfight 2 carb question

hi I sorry if been asked before my speed fight 50cc had been derstricted and I’ve rebuilt the engine a while ago with new piston rings bearings seals etc ect
I just wondered if it would make any difference if a 17.5mm carb would give it any more performance than the standard Gurtner one as I didn’t fancy going down the 70cc router after just rebuilding it about a year ago

Thanks

 

a lot more difference. Your gurtner carb is 12 mm.
But you will need to jet it to the bike.

 

Thanks for reply I’ll take a look round to see which I can fit if you have any recommendations yes I’ve seen I would have to jet down
