Svartpilen 125cc died mid ride - problem

[Kema1903]

Hello!

125cc, 2022., 28k kilometers:
My svartpilen decided to die on me mid ride, check engine light started flashing.
New spark plug, new air filter, injector clean, reflash was done at a service place.
It cranks, but doesn't start, my handheld diagnostics tool shows error code "P0201 - Injector circuit".
It has been 3 weeks and the KTM servicers are saying that they still have no idea whats wrong with it.
What do i do? They'll probably charge me a lot, I'm planning on selling it ASAP.

You guys got any advice? I've searched the whole internet and found nothing. Words can not describe how annoyed I am at all of this.
Cheers!

I know it's been a while, did you get this fixed? The only thing not on your list of parts is the ignition coil (part # 27 on this page) which can also cause an engine not to run:

And sometimes even if the injector has been cleaned and tests OK on a workbench, it's worth (temporarily) replacing with a known good one (part # 3 on this page):

Hey!
Gosh where were you before XD
It was the ignition coil

I had two 401's after this, both had these problems: Spark plugs couldnt handle my driving, had to get NGK's. Discs warped on both. Also, had to put like 200ml of coolant in both at like 10,000km's.

Other than that, awesome bike

lol! Even though I own a 125, I'm usually lurking in the 401 sub forum... this sub is a bit of a ghost town.

Glad you got the problem sorted, in a roundabout way. Combustion engines are relatively simple... fuel, air, spark, timing ... one trick is to treat those exploded parts diagrams (like the ones linked above) as a flow chart, and just read your way down the list of parts.

NGK, good call, I run the same brand in all my (previous & current) cars, they hold up to abuse like no other brand.

Warped discs is usually operator error – said with all due respect! – aggressive braking causes excessive heat build-up... Try braking earlier than you currently do, with less pressure? Warping can be caliper misalignment (rare; factory QC issue), or pads always contacting the discs (adjustment or stuck caliper)... but those issues also cause juddering and vibration, making the ride pretty obviously horrible.

Yeah I do brake late and with a lot of pressure, so it would 100% be my fault XD

A floating disc would probably solve that, but I'm thinking about doing a trip to Stelvio pass and back (about 1000km's) and then selling it right after,

I've really started to like the Honda CB650R, even though it is 200kg's and road oriented, I think it'll be a nice upgrade

How about you, upgrading to a 401 or moving to something else? I've had the 125 for a year, it never got boring haha

I'm new to bikes, still using my car license, hence the 125cc – but I think for the next step... Yamaha XSR700 Tribute (modded into a scrambler) or XSR900 (similar, scrambler mod), Ducati Desert Sled (if I can find one with service history for a good price), or, maybe get a pair of bikes like an old BMW for street work plus a Honda CRF300 Rally for the off-road stuff.

Specific bikes are more sensible... but honestly I love the scrappy nature of scramblers, head off tarmac, sling up a dirt track, no questions asked.

I'll probably keep the Svartpilen 125 around for nieces & nephews or for friends who want to have a go on motorcycles but don't have a license. It's absolutely the best looking 125, and for the used price I paid, I can keep it around.

And if I didn't keep the 125 then I'd probably still want a 401 or 701 because they are future classics.
