F1 lumpy low speed running.

<< < (2/2)

Skoti:
Fixed  :)

Decided to screw out No 1 and 3 air screw an extra 1/4 turn. Just been for a road test and it's nice and smooth now at low speed/revs.

Removed the plugs again and they are more or less all the same colour.

Amazed at how such a small adjustment can make such a big difference.

Summary:-
Carbs No 2 and 4 air screws are 1 3/4 turns out. Carbs No 1 and 3 air screws are 2 turns out.

I'm aware the normal setting is around 1 turn out but I fitted an aftermarket air filter and then read some where that they are more restrictive that the genuine Honda filter.
