How very dare you, sir, I resemble that remark!

There's also a thing called the "Svartpilen Weight Reduction Project" that I'm taking cues from...

You can drop something like the charcoal EVAP canister (it's to the left of the FuelX box in my pictures) - fuck the asthmatic kittens and all that - but it's all just plastic and rubber and hardly any weight to speak of. However, a lead-acid battery might be over 3kg and a Lithium Ion one less than 1kg with the added bonus of holding charge well if the bike's left sat a while. Sadly longer intervals for me, now I mostly work from home.

After a month and a half of back & forth with KTM I finally got the handlebar kit sorted. (Top and bottom yokes now matching colours!)

As a reminder the Svartpilen (black arrow) is a "Street Scrambler" and the Vitpilen (white arrow) is a "Café Racer" Rolling Eyes Puke

Apart from the obvious colour scheme differences they're essentially the same bike (and the same frame and engine as a Duke 390.) The physical differences are the handlebars, tyre choice and a tank bag mount, present only on the Svartpilen. I mostly zip into the City so stop-start traffic doesn't lend itself to the faux clip-ons hence the conversion.

First step is to survey the bike and make some notes on cable routing. For example, the clutch cable running behind an engine mount bracket:

And the fork height:

Then you just start stripping stuff off!

I removed the side/tank panels as precaution against tool scuffage. BTW managed to get the headlamp off still on its bracket so no need to adjust the beam angle later.

This is never a good look for a bike Smile

The kit comes with new switches, clutch cable and brake pipe as the new handlebars raise things up a bit. Clutch cable? Dead easy. The other end from front brake lever where it goes to the top of the ABS unit? Complete c*nt to get to Sad

And no, you can't get to it from above Sad Fuck knows how they get this assembled at the factory.

New yokes are plain aluminium instead of the original anodised black:

Everything routed in ready for the bracket that holds the dash display and headlamp:

Transition complete:

Brake bleed was straightforward with one of those pipes with the one-way valve. Probably pissed away 200ml of DOT4 getting all the air bubbles out. (I'm not fretting over possible air in the ABS unit as the lower half of the system has not been touched.)

Not 100% sure about the new bar-end mirrors. They're a bit odd but then so is this bike!

As a bonus job I dicked about with my collection of end-cans and settled on this one:

Visually I think it suits the bike. Sans baffle the bike sounds like a hammer-drill, very unpleasant Sad The supplied baffle (which was more just a slight restriction) didn't do much to speak of. Then I tried this common sort you put in the end:

Slightly quieter but I didn't like the tone Thinking Then I tried this sort:

https://ae01.alicdn.com/kf/H7054d2fa8da64809b90681ef4e564b98Q.jpg_640x640Q90.jpg_.webp

Which sandwiches between the link pipe and the end-can. The result, audibly, was pretty good - not so loud you can't talk over it at idle but nice and meaty with some throttle. BTW I had the seat off while testing and there's a lovely induction note with the new air filters Smile

Hopefully the weather's not too bad tomorrow so I can give the bike a road test.

Work, work and more work Sad Only got out on the bike today.

The good news is the handlebars feel entirely natural. Hardly surprising but should also imply I've put the front end back together correctly Smile Brake is good, better if anything. Clutch needs no further adjustment.

The bad news: as the handlebars are higher and I have the fancy mirrors my bike cover doesn't fit as well. Stock mirrors would have been much worse though. Might actually go back to the round ones or seek out a different style.

In my continual quest for tonal quality I've refitted the original "sound damper box" midsection:

https://i.imgur.com/IAfRn8b.jpeg

Previously I had decat pipe > mid-section link pipe > end link pipe > end can (with baffle) and now it's decat pipe > box > end finisher. BTW the end is a ten dollar part meant for an MT10 Smile

Doesn't quite follow the lines of the bike:

...but it gives the bike a simpler uncluttered look.

The previously arrangement made the bike sound like a dirt bike (big single, quelle surprise) which is fine if that's your thing but refitting the stock box has produced a much deeper note which I prefer.

In other news I went back to round bar-end mirrors for their convex nature.
