I have a 12A with RB Dellorto setup. The oil metering lines are positioned on the carb upstream of the throttle.

How does this compare with the:
1) 12A nikki carb
2) 13B fuel injected
3) 13BT

In the repair manual it looks like these lines go into the lower manifold or rotor housing on the 13B FI.


Thanks

 

The 13B's use 4 lines. Two on the rotor housings, two on the lower intake.

I can't remember if the lines go to the carb itself on a Nikki or not. Its been too long sice I've had one

 

On a 12A, they go directly to the carb. There is no outlet, both are inlets. One is for rotor 1 and 1 is for rotor 2

 

I thought they went right to the top of it, but I couldn't remember.

Mine doesn't have a Nikki, or an omp for that matter

 

Actually, the lines for the 12A go into the primaries and the oil eventually makes it down to the rotors.
