Title: fitting airbox tip
Post by: Ponty on February 15, 2015, 12:00:13 PM
Had to take my airbox off today to get the starter out for a refresh. Took the box off and on a couple of months ago to fit a new shock so I was thinking about the struggle I was going to have to refit the carb and gearbox breather pipes that have to be reattached to the air box as you put it back on. Job for someone with very long thin fingers... I used two 'tools' - a long thin wire loop - like baling wire - and a long strip of flat aluminium bar about 30mm x 3mm section. Loop the wire round the pipe and put the end of the bar opposite the loop and you can gently ease them up together with the pipe held between to fit the pipes on to the airbox stubs. You can ease the clip on the breather pipe up in the same way. Thin torch is useful too so you can see what you're up to! The other end of the bar is handy for gently easing the carb rubbers on too. Cheers!

Nice tips Ponty

I'll try and remember that when I get around to pulling my carbs out for a clean and service.

Great tip  :good2:

If I still had a stock air box I would try it . However, mine pissed me off over 10 years ago and it was run over by a garbage truck for it's insolence .  :diablo:

About 8 years ahead of me.. Threw that POS box away. Never looked back.  Now it is almost fun to work on the carbs not to mention the ton of room I now have where that box was.  :good2:  :drinks: Happy dance...

Too bad the carbs are in the way, I could toss in a raw steak before a long ride and have a cooked steak when I arrive. I guess I need to find other uses for the extra space. Might be warm enough to cook eggs???

I had a leak in my carbs once...... :ireful:..... After fighting to get the OEM air box back in, I ordered a set of UNI pods from RPM and 86'd the stinkin' air box..... :dance:

  You guys all know how easy it is to let the rear subframe pivot down on the bottom bolts,, right ?

Oh yea and putting the crankcase vent hose on is fun to  :lol:  My FJ will never see an air box again as long as I own it. I struggled with the POD vs air box deal for a year or two. Just kept putting up with it.  Even cut it down and modified it.  In the end it was POD's.  Power is not an issue with me up to a point anyhow but ease of maintenance, loosing some minor amount of weight, and having more room gets my attention.

2 of them have air horns. And lots o space. And the third has room for a turbo and a water injection pump.

Three FJs here. Fitted with the OEM airboxes. Gotta have an installation routine down. I guess.

Letting the rear subframe pivot down is a good plan! But I've got panniers fitted and getting the rack off is a pain. I've a mate cooks the family lunch on the manifold of his Landrover Discovery if they're going any distance... Cheers!

Way back when I had my airbox, I used the subframe lowering trick all the time. It gave just enough clearance to get the air box back for removal...the problem I had was reinstalliation of the air box.
Yes, the carb boots were tricky but the real pain I had was reattaching the crankcase breather hose to the bottom of the airbox.
My solution was to remove the oem plastic airbox/hose fitting and install a threaded brass hose fitting.
This brass fitting was connected to the vent hose with a hose clamp...and the threaded end slipped into the hole in the air box and used a wing nut and washer *on the inside of the airbox* to snug up (finger tight) the brass fitting.
To remove the airbox I simply removed the airbox side cover, pulled out the filter panel and reached in with my fingers and unthreaded the wing nut, air box came out easy and was just as easy to reinstall.

Hope this helps...

Not to hijackthis discussion but can anyone link me out to the mods needed to the carbs after fitting pods? I (likely mistakenly) didn't got the UniPods from RPM but got some knockoff individual pods from a local seller.
My 91 has been repainted, has new graphics and a few other bits and bobs. We are presently in the middle of the largest snowfall in our recent history so still lots of time for tinkering...and asking questions here...

thanks in advance,
Don

Don, its hard to tell from your bike image but it looks like you have an after market exhaust. If so, then you will be bumping the main jets up to 112.5 or possibly 115. You will need to get adjustable needles as you will need to raise them up a notch. Since you are already inside I highly recommend bumping the pilot jets up to #40. This will make the bike easier to start when cold and it idles better for me. And since you will run the risk of stripping out the soft fasteners on the carbs, order the SST fastener kit from RPM. And if you are doing all the fasteners, why not just rebuild the carbs so you know they are fresh and good for many more years of Kookaloo. How long has it been since you had your carbs serviced?

FYI, Randy at RPM rebuilds carbs, Mike here in San Dimas had them recently done and he is really happy with them.

Almost forgot, sell the cheep filters and get the UNI pods. The cheep filters are not likely to filter as well as the UNI's, and they can be washed and reused. Some brands tend to fall off, then you get zero filtering on that cylinder.

Carbs were done in the fall. I'll give Randy and email and ask him to put a package together for me today :-)
the muffler is a F1R, so yes aftermarket.
image attached of new cheap pods and exhaust.

thanks as always.

Once you get the carbs sorted and running again you will hear a new sound. It is a very nice sound, when you twist the throttle you will hear all four cylinders taking a big gulp of air. This induction sound is music and very addicting. Something the air box keeps to its self, greedy little PIA. Looking forward to your next post.
