Airbox on 1998 VFR

I’m trying to refit my airbox and am having a hell of a time re-connecting what looks like a breather hose on the front left side of the box. Short of having universal joints fitted to my wrists and fingers this would see to be MFI as the box almost has to be in place to get the hose to marry up with the connector on the airbox which leaves no room for fingers etc. Anyone got any suggestions, tips or workarounds to help with this.

 

Is it the hose from the front bank pair valve? Rip it all out , fit blanking plates and plug that hole. Youll never have to worry about it again

 

Thanks Darth, not sure what it’s purpose in life is ( other than to frustrate the sh1t out of me) It is about an inch in dia and connects to the front left corner of the air box) it then disappears down into the guts of the bike somewhere behind the left radiator. I’ll have one more go at connecting it tomorrow and then try your suggestion and see what happens GeoB

 

I can remember that bloody pipe, nearly mpossible to get back on. Do a search on here for pair delete /blanking and get rid of all that emission stuff. I got some aluminium sheet from work and made my own blanking plates.

 

Darth,

I managed to get the hose re-connected with the assistance couple of cable ties, a lot of swearing and some ugly threats. Hopefully I’ll never have to take it off again.

thanks for your help and may the force be with you

 

I use silicone spray on hoses like that, to ease them back into place from odd angles.

 

Terry,

thank you for reply. Good to know and if I ever have to do it again I’ll try that

 

I just removed the PAIR system........ I also have these pliers I use for hoses..... long handled and long nosed. Got them as part of a set of long nose pliers.......

 

Well damn, that's ANOTHER tool that I need to buy...thanks raYzerman!

 

What if the hose and where it connects are both plugged? I'm asking as I'm planning on removing the air box this fall to have the injectors cleaned and I can foresee not being able to get it hooked back up.

To be clear, you are talking about the flapper valve solenoid and associated vacuum lines? This draws air off the throttle body vacuum side, and uses that to suck closed the flapper valve when the ECM activates the solenoid valve. So long as there is no vacuum leak back to the throttle body then the rest doesn't matter (except of course the flapper will by default stay wide open, not going to get into an argument about the merits of that one...). AFAIK, the solenoid valve has no feedback to the ECM so it won't know/care that it is unplugged.

 

I have had my airbox off a couple of times, and while it's a job, it's not that bad. The two larger hoses that connect on the bottom are fun but you can do the hoses up while the bottom is loose. Just look at the hose routing diagram in the manual, and you'll be good to go. I replaced the hose to the flapper with one a bit longer to give me a bit more room. Removed PAIR system.

 

Thanks raYzerman - those pliers look brutal - something that a dentist or gynaecologist would use. Did removing the PAIR System makes much of a difference to your bike?

 

The PAIR system is a passive system allowing filtered air into the exhaust ports (after combustion), intended to help burn off unburned gasses. Taking it off just means the exhaust isn't getting any air into it.... no performance gain whatsoever, just loses weight and cleans up the engine bay.
