nc35 carbs on a UK spec nc30 engine

[skinnydog0_0]

Hi all,
Has anyone ever run a set of 35 carbs on a uk spec 30 engine?
I understand that the uk 30 engine has 120 + 122 jets in the standard carbs which are bigger that the standard jets in the 35 carbs.
Should i use the 120 jets for this set up?
The engine is standard, and i have a micron race end can.
any advice or thoughts much appreciated.
Cheers

Been covered many times on the forum, try a search theres many different setups you can go for but in general it'll give you a better midrange.

No. NC35 carbs run smaller jets that NC30 carbs. You want to be around the 110-112 ballpark.

yes i have and in short

3/4 yamamoto system
UK NC30 & Jap spec bikes
Both responded very well with std air filter
and 110 and 112 setup
nothing else changed, pulled like fook.
