Can anyone provide a picture of a vacuum routing diagram of their airbox on for an '88 1000f.

I've been having issues trying to get my bike to run properly, and I've done just about everything I could to my carbs and the bike has had a whole top end rebuild and compression check. The bike came with those small holes for the pollution control tubes on the cylinder head (above the exhaust pipes) but I plugged them because I could find none of the OEM tubes, and after everything I'm figuring this is the issue, I've taken out a major component of the vacuum system and can find no OEM setup for its original layout.


Just a poor college kid looking for some help.

 

I've yet to look through these, but I do have the shop manual and I can't find an exact routing diagram for the vacuum lines in it, the guy I bought the bike off of had damaged the airbox where the original diagram was pretty much made unreadable.

Well after looking between a couple different manuals it looks like I need to replace these little emissions pipes but they seem to not be available for purchase anywhere.

Part #'s

18640-MM5-740

18641-MM5-740

and no retailers specify if these come in a pair or if I have to buy four separately

Seems like they come in pairs

Surely any decent quality hose of the correct diameter will do the job ?

 

Well looks like you found what I couldnt, I wish I could use any hose but It'd be fairly difficult to fabricate something to bolt on the cylinder head and have my own hosing run out of it and seal properly, well at that price I sure hope they come in pairs.

Thanks for being so friendly guys, hopefully this can fix my issue with no power up top. Now its time to save up money for these. Also sorry for posting it in the wrong place, it seemed like a pretty random question so I just dumped it in off topic to be safe.
