Sorry Miles I can't help you.  I was just about to post the same question.  2000 I/S with 56,000 miles.  Getting a lot of pops on deceleration.  It's time to do something.  Either replace all the hoses or do the "Stealth" desmog.  I'm not doing anything that can't be reversed.

You will need to loosen the front and rear tank mounting bolts and lift the tank up a little and move it to the right a little.

those lines go under the carbs and hook into the pair valve. here is what i did. take the one on the right side loose. run a peice of strong string under the carbs from the other side, tie it to the hose (tight) gently pull the hose under the carbs to the left side. you should be able to get hold of the t. now replace both hoses. tie the string to the end of the new hose and run it back under the carbs the other way and gently pull the hose back to the rt. side.

worked fine for me. don't forget to replace the rubber caps on the intakes that don't have hoses, and do not lose the little tiny hose clamps. make sure you use viton hoses so they will last. i made mine a few inches too long, that way as the ends get brittle i can cut 1/4 inch off the end and have pliable rubber again.

I switched out all vacuum lines this spring, not a bad project.  I recommend pulling tank and airbox along with an email to Rich at Redeye tech.  Top notch products, great prices and quick service.

Noooo...stringie!

I just "replaced" one hose; the one that runs from the middle left-side intake tube. Was going to snip the cracked half-inch and put back on.
The whole piece of hose ended up in my hand.
Exam reveals that both ends were cracked. In addition, several 'middle' inches of said hose were full of cracks. Rotten. Presumably other hoses are the same.

Question for vacuum gurus: can I ride it this way till I get some hose? Can't see it being much worse than with the hose full of cracks. (Not much vacuum).

I'm not a vacuum guru but am quite sure that your bike would run very lean without one of the vacuum hoses. Why risk it?

+1 on this advice.  I ended up replacing the carb drain lines, fuel lines, and o-rings while I had my carbs out for cleaning and new jets.  A lot easier to work in there with the airbox removed, plus a good time to clean all the accumulated dirt on top of the engine.  Redeyetech vacuum lines and plugs are the way to go.  I bought the OEM drain tubing set from HDL...very pricey but the tubing had all the correct bends (not really a big deal).

Do it right the first time and you won't have to worry about doing it again for another dozen years.

Good luck and keep us updated.

It's been a while since I did this, but as I remember I disconnected one end of the old hose and attached it to the new hose with some tape.  Then I grabbed the other end of the old hose, and pulled it so the new one would follow the exact same path.  Finally I cut the new hose to the proper length and reattached both ends.  MUCH easier than trying to fish the new one through.

Thought I'd try the Honda dealer first, since I was going to town anyway.

Uhm...nope. No vacuum hose. It's been discontinued; says he.

Li'l wire clips? Uhhmm...nope. None in stock.
The bigger one, for my fuel hose? Nope; sorry.
Vacuum caps? There's a part number. But oops - no. Haven't got any.

That was SO helpful. Jeez. It's just little hose clamps! A length of hose!

Off to order from Redeye.

I have desmogged the bike a long time ago but what I remember most about Redeye was a vacuum line I purchased from him.

The "rubber" tubing he sent had an additional hard plastic tube cut to length inside the tube.  thought this was a very good way to add a lot of extra years to the life of the tube since the inner tube would prevent the outer tube from collapsing which is the usual cause for the failure.

Good stuff!
