I'm a frame maker for well over 40 years now, and by my standards, Karl Landrus' stuff is quite good. Well, that's a bloody understatment, if ever there was one.

Waiting time - well yes, you get in line. Dependant on the frame, it's can be at least 2 weeks for me to make one , all by myself, with hand tools, by my spinning lathe and mill handles and laying each bead. And then the time wait is down to where you are in line. I also make alloy 'drop tanks' for CRs - 500s mainly - and if someone wants one, they pay $1300 AUD, and, at the moment, with the commissioned frames / swingarms / tanks and other things I have 'on list', you'd not get one for at least 8 months. Ad in my teaching jobs, and I'm a busy Bear.
You pay , and wait, for quality - I'm sure you understand that, but it read as a bit of a complaint. Skilled artisans, are not in it to flood the market, nor get rich quick. We leave that to 'dealers', and the like.
As it is, so many AFs require the reshaping of the bases of std tanks / big tanks, to clear the engine. So, all the fuel, is carried above the engine. It's a bit like shooting yourself in the foot. I truly hate big tanked AFs......... Conventional back bone frames, allow you the option of dropping the fuel way, way down.
AFs, carry their fuel high - and if you want a bigger tank than the piddly (especially so as you go into later model donor CRFs) std tanks, you are carrying it ever higher. I've done quite a few AFs since 97, and it's one of the (quite a few)things that I dislike about them. Don't get me wrong - with all of the idiots who can't do basic maintenance on their 4ts, there's a hell of a lot of 'donor bikes' out there, that make a great new place for our old, wonderfully basic / perfectly primitive engines to live in.
I've a fellow that wants me to do an 'airshroud drop tank', for a 13 CRF build up I did but it would be a very complicated thing to do. "Airshroud Drop Tank" in that, like how a few big tank manufacturers get fuel capacity from incorporating the shrouds as part of the tank, but then me taking that idea, and bringing those "wings" way, way down.
If the bloke does come at the cost (a Lot more than I charged him for the AF conversion - which, I really don't do any longer, other than for a friend or two - I encourage people to make their own as it's basic fabrication, that most can do, and people should do their own bikes - not bloody pay someone else to do it) , it will be an interesting project.
I don't keep much in pictures, hell, I took precisely none last weekend at the MXDN, but here's a couple of ancient pictures of one of my steelie prototype tanks, during the (very) rough build up phase. They now go all the way to the ignition cover on the LH side, and the add on 'ears' at the forward sections, are a full, much more contoured part of the tanks. As you can see, it's the reverse of the classic , up to 86 (87?) Works RC tanks, with the radical drop to the LH side, but I also go as far down as possible on the RH side, dependant on the KS lever and pipe used: I build them to take 2002 / 2007 CR125 /250 shrouds:
Yes - there is room at certain areas to drop sections down on an AF, with a specific build tank. Much is dependant on whatever 'solution' the AF builder has used to do the head steady mounts. So, with an alloy tank, if you want to go for it, you can put various drops / pockets in to increase fuel capacity, whilst trying your damnedest to get fuel as low as possible. I'd be looking for every opportunity to do so, and that would be part of the high price of the tank. Every extra alloy piece, every extra inch of weld, costs. In my drop tanks, there are over 60 different pieces / weldments, for example.
I'm obsessed with lowering the fuel load in any logical way I can. That tank, is a 14 litre one - it wraps around the barrel, but with good air flow / ducting, there is no fuel boiling / or (extra) engine overheating - well, engine overheating, is par for the course on my 500, in the technical single track I do, hence the rad fans you might have spotted in the pics. If you look again , note how low the top of the tank is - it's several inches in height below a standard tank, and the seat ends up perfectly flat. It changes the feel of the std bike hugely - fuel far far lower than std, yet another 4 litres, with a far slimmer profile to it. It uses a Mikuni vaccum fuel pump that mounts on the tank, just forward of the carb, to transfer the fuel to the RH side of the tank.
