Need Visual Confirmation of Carb Hose Routing

indr · June 22nd, 2013, 08:41 PM

Hello.

This is a picture of a stock Ninja 250 carburettor from the top.

See how the hoses running on top of the left carb are criss-crossed? Could some one please verify which ports these go to on the right carb?

I ask because, even tho hoses in all carb photos are crossed, if I were to plug them on crossed holes, they wouldn't fit.

I.e. if the fat hose was going to the port on the engine side of the carb, it'd be too big (the hose's inside diameter). And if the skinny hose was going to port closest to the airbox, it'd be too small (the hose's ID). So, does the small hose route around the big hose underneath and between the two carbs?

The photo you posted is correct.

Yes. But I can't see which hose goes where.

I'm assuming your talking about the right carb.

The fat hose goes engine side and the thin hose goes airbox side. They start off the other way around on the left carb and cross over each other before connecting to the right carb.

There should be some connections that pivot so you can move them around to make it easier to connect the hoses.

Hope it helps. Not exactly sure what you want to know.
