Hi all i have a gsxr 400rr 1988, in the middle of the carbs the bottom hose is the fuel inlet but what is the one on the rail above it?

Many thanks in advance. Simon.

Hi Simon,
Its just a air intake for the carbs, ther should be a pipe that fits it and just sits up on the top of the air box.

Many thanks.

Ive got starting probs too, carbs stripped and rebuilt and ballanced, plug leads around the right way, fresh fuel going in. It just keeps turning over and over and now and again i get a pop and flame from the exhaust but it will not fire any ideas
Cheers.
