Yamaha carburetor manifolds

With the old Yamaha 's it is always very difficult to re-fit the old and many times hardened rubber manifolds from the airfilterbox to the carburetor.

 

But there is a little trick that works sometimes. Take for example the Yamaha DS6. This bike has an airfilter box that slides onto the batterycase and is then attached with a screw that also functions as "ground" for the battery. My DS6 had not run for 3 years so the carburetorslides were stuck into the bores of the carburetors. After re-assembly of the carburetors I slid the manifolds over the airfilterboxat an angle of about 45 degrees:

After doing this I moved the whole assembly carefully in from the left hand side (right hand side is impossible anyway, as there you have the oiltank). The manifolds are always more soft on the airfilterbox side, so this goes well. When you move the assembly in place, be sure that the manifolds slide already with their left hand sides slightly over the carburetors.

Now push the airfilterbox carefully in place against the bracket where it is attached.

Make sure that the manifolds are now properly around the carburetors and tighten the metal bands.
