Zool, welcome to the 690 club!

I plan on making a 750mi journey on my SMC this year, from the very south to near enough the very north of Britain. The three things I plan to sort out before that trip are;

Luggage Rack
Touratech made a mild steel one for KTM's catalogue, but sell a stainless version for less on their website. Will be making my own panniers though, the touratech alu ones are ridiculously priced.

Seat

Any tips on tires? the ones on the bike are the originals from 2006. They are hard as stone and probably were not all that great to begin with. I was going to go with power pilots, but Ive read that maybe those were designed for bigger heavier bikes . Also maybe there is a nice cheap alternative.

Get something SM oriented. As I understand it a bike like the DRZ wont have enough weight and grunt to deform something like a power pilot, which means you will have a hard time warming them up. There are plenty excellent SM suitable tyres around, and you can even mess with combinations of front/rear.

Common choices for SM include:

Dunlop Mutants
Apparently a good general purpose tyre adapted specially for SM conversions. From what I have heard they last well and grip plenty. Better than some on loose surfaces but by no means great.

Continental Contiforce SM
Good grippy tyre, apparently softer than the Mutant, I found my 690 ate the rear too quickly for my liking but the DRZ would probably be kinder to them. Another well regarded SM tyre. Usually found for a decent price too. Not as good as the mutants on loose surfaces.

Pirelli Dragon Supercorsa
My 690 came with these, their grippiness is only surpassed by their costliness. They function in the wet but they don't clear water well enough for my liking. They absolutely suck on any surface not road-like.

Avon Pro Extreme Rain (aka PXR)
Super soft rain tyre that is not even road-legal on most sport bikes, they cost as much as the Pirellis. These are what I am wearing right now and I have to say they are very confidence inspiring. I can stop in the wet almost as well as I could with the Pirellis in the dry. I live on a small island that gets an awful lot of rain over the winter so I am wearing them front and rear a the moment but when it gets drier the rear is going to get torn to poo poo. I will be replacing it with the;

Avon Distanzia
Hard wearing, grippy and surprisingly capable off the tarmac, it's a fairly popular choice on both ends of the bike or combined with the PXR on the front (this seems to be an immensely popular combo here in Britain).

And I severely wanted a 690SMC... until i did some research.
Quite a few engines have blown up with relatively sedate riding, and a guy has had his 5th fuel pump failure... ok i think ill wait a few more years on the 690s.

As a 690SMC owner I keep up to date on appropriate forums, and I have not really seen a significant amount of total engine failures (no more than industry average). The issues that seem to plague the 690s are stalling and snatchy throttle, which is fixed by proper mapping and the required adjustments by a competant mechanic. In fact, competant mechanics seem to be the real issue with the 690, there just aren't very many. KTM changed a lot with the new LC4 and many shops haven't caught up on their training it seems.

As an ex-service engineer I can tell you that if a part fails 5 times (and doesn't have a high rate of failure otherwise) it is almost categorically not the part, it is another associated part, abuse or the mechanic at fault. No-one seems to teach proper diagnostic theory these days :(

As for mine, well it is almost bone stock and the only issues I have had are with the cam-chain tensioner, which seems a little sensetive to proper warming-up of the engine.

If the engine was that much of a grenade they wouldn't be tuning the balls off it and sticking it in endurance races like the dakar.

Sorry if this sounds a little ranty but there has been a lot of people putting the design at fault on other forums when it seems to be mostly the service side. KTM need to get their house in order on the service side, not development.

TL:DR; Don't be afraid of buying a 690 if you have faith in your dealer to set-up and service it right.

Also, I need to change the oil. I used rotella t I think it was on my last bike. Will that work just fine on mine? I haven't downloaded a manual yet. How often should I be changing the oil and filter?

Reccomended oil change on the 690 LC4 is every 3000mi, but if you hoon it around you might want to change it more often.

The engine is designed for 10W60 full synthetic (KTM obviously reccomends the pricey Motorex stuff) and you should be changing filters and screens when you change the oil. There are two different filters to change and as I remember two screens too. Seperately they are expensive but you can buy a service kit (KTM part no. 00050000069) that has everything you need but the oil.

Power mods for the 690 are largely an exercise in large expenditure for little gain. The engine is the strongest stock engine in it's class and I have only heard of meaningful improvements from drastic work like reworking of the head, increased compression and entirely replacing the throttle body and EFI unit.

The bike can be most improved simply by having it set up in a competent garage. The EFI is finnicky and needs to be trimmed and adjusted right.

Edit: Not that it's going to stop me experimenting. I want to replace the entire airbox with a pod filter to give me more space and I want to replace the exhaust with something less huge/hot.

I was following the work some Austrian guys were doing on another forum and it seems the problem is not fitting a new can to the 690 but retaining the airbox after changing it. The airbox is a very interesting design that straightens out the power curve into the near diagonal line that it is. Unfortunately It only seems to do it's job properly when it's used with the hot, heavy stainless lump that is the stock exhaust. Fitting an aftermarket can and factory remap will do little more than give you maybe 5HP on the top which it apparently robs from the midrange.

The only solution to this (that the Austrians found, anyway) was to do away with the airbox at the same time as the exhaust, replacing it with a generic pod filter. The stock ECU with factory maps can in no way handle this, so you have to either install a piggyback unit, remap the EFI with a Tuneboy or replace the entire ECU with a third party module.

Removing the airbox had the effect of shifting the entire power curve down the rev range by about 700-900RPM while maintaining low and mid range. The other benefits being a large amount of space freed up for extra fuel/storage under the seat and increased intake noise (if you like that sort of thing).

Bootnote:
The 690 Rallye, which is based on the same engine and chassis uses an FCR flatslide carb and an even weirder airbox. The factory team apparently didn't trust Keihin's EFI enough to put it racing (which I heard they had initially intended to).

Putting new tires on the DRZ 400 this winter. Anyone have experience with Avon Distanzias? Theoretically they are exactly what I want and I have seen some good feedback elsewhere. Any thoughts on it or any other tire for a 75% on road, 25% light off road/gravel tire?

Avon's Distanzia is an awesome winter sumo tyre. The generally favoured combo is a Distanzia rear with their Pro eXtreme Rain on the front.

The PXR is super soft but on the front of a sumo it will last for a good long while and it makes the bike very sure-footed in the wet. The Distanzia is tough enough to survive as a rear on my SMC while still providing decent hold in the wet.

Wait, is that something that would even be covered?

Did you note the error code? The FI light will blink in a certain pattern (long or short flashes) and there is a table in the user manual troubleshooting section that tells you what they mean.

Even if you can't replicate it, the dealer can look into the EFI log (which records all errors until they are purged by the mechanic) and find the issue.

I'm a similar weight to you and I had similar trouble, I played with the damping and compression for a while with not an awful amount of luck. I increased the rear pre-load, which made it a bit better, but still not quite right. Then I returned to factory damping/compression settings when I serviced my forks and suddenly everything was rainbows and puppies, different bike.

So in short, try doing nothing but increased rear pre-load, it's pretty much bang on in my opinion.

Looks righteous with the white wheels, just when I thought you couldn't make a white Duke 3 look better...

Edit: as for first bike, it's a little hairy with the very direct throttle response the EFI gives. I had a 690 SMC as a first bike and if you're sensible it shouldn't be a problem. There is a throttle map selector somewhere, probably under the seat, I would set it to 'soft' until you get to grips with the bike. Even after 30 months of constant everyday riding I still use the soft setting when it gets snowy/icy. A 690 on the hardcore throttle setting will wheelie if you sneeze too hard.

I'm too used to the slipper on the 690 and now I'll accidentally 'chirp' the rear when I borrow other bikes. That said, dropping the clutch completely at speed still takes some extra balls that I don't often have. The full unbridled engine braking on the 690 is intense.

I'd rather see a new rider on even the hairiest of motards than a 600cc i4. Even if you loop the bike it will likely be at low speed and the bike will be able to ride away after. My flatmates '03 Bandit 600 was unnerving after having ridden my SMC for a while. Taking off on the Bandit I was completely underwhelmed for the first 5 minutes.

Fellow 690 owners: what tyres are we all running?

I swapped in a Conti SM on the SMC when some little pikey put a stanley in the original pirelli rear; I really don't have anything good to say about it bar the price. For starters I felt it wore out too quickly, and I don't know if it just didn't work right with the existing Pirelli on the front but I never felt really confident with it.

Swapped out to Avon PXRs front and rear for the winter of 09 and they were stoppies-in-the-wet awesome, but the rain didn't come like it did in 08 and I wore out the rear by spring. I swapped the rear to an Avon Distanzia SM, which is a popular combo on big sumos here in the UK (where we have to endure a fair amount of wet riding) and I have to say it's pretty much spot on in every department; handling, cost, wear. The PXR on the front is only now getting to the end of it's life and the Distanzia looks like it still has the rest of the summer, maybe longer left.

Everyone uses the curb, they purposefully made all the curbs nearly flush with the road surface. The last corner sees a lot of slides and bumps as people try to power over the line. Even riding the road day-to-day I've had the back step out there when I've been too eager to get on the power. The second to last corner is the worst for bikes though, all the corners before it have a camber but that one is completely flat and if you're not expecting it you can expect to be pulled out of the hedge. When we have inter island events or visitors it's not uncommon to see a few offs there.
