No clue what size mikuni you need, but i have 3 38mm mikunis, i could probably make 1 good carb minus choke and throttle cable out of them. If thats too big (might be), i also have a 32 or 34mm mikuni.

My engine is 400cc inline twin. Mods are:
custom high flow exhaust (home made, SS)
Uni Pod filters
making around 40hp

i dont either i need another to do a blow through setup but if mikuni is out then there is this 2 barrel carb but is expensive

My Tecumseh Star motors have extensive porting, race pistons/cranks/rods/cams, Methanol Tollottson carbs, 3-stage headers and externally mounted block brace-plates to help hold everything together.

I'm well into my second race season with my old Star motor and just swapped a KT100 for another used one I'm freshening up to have around as my spare.

Nope, both 4 stroke bike engines. Mines pretty low power, made in 1978.

He's asking how you found out how much HP your motor has; ie did you actually dyno it, or are you just guessing.
