Carburetor photos
From Ninja250Wiki
So, let's say you've cleaned your carbs and are ready to reinstall them, but you have all these hoses lying there and you can't figure out where they go. These pictures should help. There are also detailed pictures in the carb cleaning article, and you might want to look at the parts diagrams or the [Ron Ayers fiche].
First, the California difference. The T fitting shown in the photo below is unique to California-spec bikes. If you have a 49-state bike you shouldn't have this. That is a tube that hooks up to the emissions magic box on cali bikes
The tube tube that the T-fitting is on is one of the the vacuum tube. Normally, that tube would connect directly to the petcock with nothing along the route, but california likes to mix things up.
