1982 Honda c70c with modified 110 engine help please

Hi everyone, ok first I apologise if this is the wrong section to list my thread in so admin please move it to the specific please if need be....

Basically I have a 1982 Honda c70c with a modified engine..

I have completely stripped the 12v c70 engine and fitted a brand new crank and Conrod kit, fitted ATC 70 4 speed gearbox, 110 pit bike barrel, TB 52.4mm high compression piston, and a late 12v Honda c90 head with bearing cam..iv also heavily opened out both inlet and exhaust ports...

Iv also custom made a 36mm large bore exhaust for her along with a foam open air filter..


My question if possible, what would be the correct carb I need and jetting for this type of set up???? I understand this is a (how long is a piece of string) question but would appreciate any info please.....

Few pics









Atc 4 speed box





Many thanks

Personally I would start at 110cc jetting and work from that,
Also I would get a carb jetting pack rather than buying individual jets
