I've finally been able to get back to the shed to continue with this fix.

Looks like it is fixed, but not fully.

I've a wealth of practice removing and re-installing the airbox now. A simple change in sequence from the Yamaha & Haynes method of install carbies to intake boots then 'push' the airbox over the back is now put the airbox on the carbies, then push the lot into the intake boots. Waaaaaay easier. This was with the subframe top mounts removed and the bottoms loosened.

I did try OldRiders' method of cutting some holes in the back of the airbox to help align the base of the airbox boots, but this is quicker and easier.

All told, not as easy as PODs, but, just personally, I don't like the induction noise and feel I get smoother power with the airbox on.

I feel the aftermarket pilot jets are just not quite right, so I've bought some OEM jets of the same size and will fit them later. I did check all points for vacuum leak and found none. Intake boots are good, hoses, caps, CDI hose, etc, etc, all ok.

I went back to super basics as Phil suggested and checked the throttle cables, all good, snapped back ok.

It finally came down to the cable free play adjustment at the carbies was a mickey whisker out. A 10 minute test ride and all is ok.

I'll be pulling the carbies one last time, swap the pilots, re-balance/sync & then re do the mixtures.

I'm really not a fan of the Motad exhaust system note. They are beautifully made, super quality welding and are well worth the coin they cost. Unfortunately I like the FJ as it sounds in OEM config, so I'll have to think about changing the headers out for original, but not yet.

On the end part of the test ride, although running a bit rough, Bendy HAMMERED!!!!! She certainly does have some Kookaloo!!!!!

Hey Troy I got an airbox that to date have tried 20 hrs to stick bank in I removed the subframe bolt push it back push in airbox but can't get all four air box mounts to fit at one time I tried cable ties it all together and fit as one unit last time I tried two days ago was at it maybe 5 hours straight till I had to walk away before I exploded

G'day Steve,

I believe it is the sequence of installation that might be giving you grief.

Step one remove the two top subframe bolts. Make sure you have a block of wood, wadded rags, etc. to support the subframe at the height you want (the subframe can sag onto the rear wheel and scratch the subframe lower front mounting point tubes against the footpeg bracket).

Step two, loosen, but don't remove the two bottom subframe bolts (the ones that go through the footpeg bracket).

Step three, (carbies floating free with cables attached) push the carbies into the airbox, check seating, and tighten the ring thingy screws to hold them together nicely. You'll have plenty of play to get it right. NOTE, as you've spent hours on this already, try removing the subframe enough to completely remove the airbox and 'bench fit' the carbies to the airbox. You'll find they need to seat at the bottom first. Do it a few times to get a 'feel' for how they want to fit on. Also, use rubber grease, not too much, but use some on both the airbox and the inlet manifolds.

Step four, set the height of the subframe so you get a good angle to push the carbie/airbox set back into the inlet manifolds (remember lower bolts in but loose). Although stiff, it should sort of snap into place. I'm not very strong and I had to lever them on from either side. It will be harder if the manifolds are old and hard. A heat gun on them might help, but I've not used that yet. Don't forget a little rubber grease.

Step five, curse me for giving you instructions that don't work for you, or if it works, don't forget to tighten all the manifold screws.

Step six, beer helps with either celebration or commiseration.
