Vacuum lines

[Paul Carver]

   2000 Interstate - While changing the o'rings on the intake manifold, I found that a vacuum hose was cracked. My bike has a little over 100,000 miles on it so that is no big surprise to me and would like to change all of them at once. I called Niehaus Cycle in Litchfield, Il and they told me that it would be around $100 if they did not have to remove any carburators and around $200 if they did. Does anyone know if this is necessary to do this job? Dumb question: where do these lines go to?
   I have had some "popping" lately and am hoping that this is the reason since changing the o'rings in the manifold did not make any difference. Thanks for your assistance!

Run down to your local auto parts store and get 6 ft of 5/32" ID Washer/Vacuum tubing.  It is a thicker walled tubing that will not collapse under the vacuum. 

Remove the old hoses one at a time and measure the new hose and install...that way...you don't forget one or cut one too short.

Check this link on our Shop Talk page:

It refers to Vent Hoses which most of us call Vacuum lines.

It's not a hard job.

Doctor J has that right.  My 7 year old Grandson, who's dad owns his own auto repair business changed mine out the last time.  Littler hands..........

We already had the tank and air box off, so it wasn't all that hard of a deal for him.    He wants to be a Motorcycle Tech, so figured we would give him a good taste before he actually heads off to Tech School.   He might change his mind by then.

I HAD THE POPPING NOISE TOO UNTIL I TIGHTENED THE TOP CLAMPS OF THE INTAKE MANIFOLDS.  THEY WERE LOOSY GOOSY.  CLEARED IT RIGHT UP.  READ THAT INFO ON AN EARLIER POST.  FUNNY THING IS I HAD TAKEN MY BIKE IN FOR A 24,000 MILE SERVICE AND EXPLAINED TO THE SERVICE MANAGER THAT I WAS CONCERNED ABOUT THE  POPPING BUT WHEN I PICKED IT UP 624 BUCKS LATER ALL HE COULD TELL ME IS THE BIKE RAN LIKE  _ _ _ _ AND I'D HAVE TO MAKE ANOTHER APPOINTMENT AND PAY BIG DOLLARS TO HAVE THE CARBS REWORKED.  I HAVE NEVER BEEN BACK AND WONT GO BACK.  TIGHTENED 6 SCREWS AND NO POPPING.  ITS UNFORTUNATE THAT I HAVE THE APPARANT WORST DEALERS IN THE SAME MARKET AS THE BIKES WERE BUILT.  THIS WEBSITE HAS SAVED ME BIG MONEY OVER AND OVER AGAIN.
