QuestionI have a used 1986 Honda Shadow 1100 and I have found two vacuum lines unhooked. They are located under the gas tank and they connect together with a "T", the third line goes into the carburetor. Any ideals of were the other two go?
AnswerVince,
they are probably part of the emissions
system, maybe go to a control valve,
air cleaner box or other evap canister etc.
The fuel lines have a "T". One line
goes to the fuel pump and the others
to the carbs. Is the bike running?
Look on the inside of one of the bikes side covers,
possibly the left, for a sticker with
your vacuum hose routing diagram on it.
This should tell you where the hoses go.
Hopefully the side covers are original
and the sticker is still there?
