Diagnosing the problem as low fuel pressure was a testament to your skill. I suspect that had the dealership came to the same conclusion, they would have thrown in a fuel pump, and when it didn't fix it, it would still have wound up at your door. I believe I too would have ordered a fuel pump after seeing the fuel pressure reading. What made you continue the diagnosis after the fuel gage reading and find that split fuel filter is evidence of skill at another level. You are a true master, Jim and your videos are the best on KZbin.

[@SuperbikeSurgeryTV]

Very kind words mate 🙏 I genuinely appreciate your positivity, along with all the other encouraging words from everyone else. People say KZbin comments are a dumpster fire, but my experience has been almost completely positive. Obviously, there are always going to be a few nasty people out there. I think it's got something to do with the subject matter. People who ride bikes are generally really loverly people. Thanks again for your comment, and thanks to anyone who takes the time to read this. 🙏

Great job identifying the actual problem. Just shows experience, knowledge & the correct equipment is needed for these modern bikes.

I am so glad that I grew up when bikes just had a carb and points ignition. No wonder dealers make a fortune out of people when a fault occurs. The average rider these days would not have a clue! That also includes me.

So good to see a proper diagnosis and not just the firing of the 'parts canon'.

[@N269]

I did that the other week.... only to find a dud spark plug, BRAND NEW!!!, and was firing as bright as the sun, but didn't work when in the bike... no compression test could have figured that. Loose spade connectors is another "sometimey" problem (such as an injector plug/connector) - and finding direct replacement wiring injector (and others) connector-plugs is ny on impossible for so many vehicles! Try Cycle Terminal in New Jersey... Joe does have a fair few.

[@gregtaylor6146]

Your fighting with those 10mm bolts with a crappy little spanner had me in stitches .... yes, you (and 99% of us) should have used wandered off and got a socket, but we don't, and for THAT solidarity with your audience, I salute you Sir. On that basis alone I subbed, keep on keeping on!

[@matthewharmer1656]

Superb diagnostic video, I have in the past ,first compression test, second fuel pressure test,even sometimes a leak down test, these easy tests sometimes finds faults without even opening up my electrical diagnostic kit bag.

[@SuperbikeSurgeryTV]

I completely agree with you 100%, That's solid advice 👌 👍

[@pebrede]

Split filters happen often on the old (80’s) k75 / 100 BMW’s with KJetronic injection, from new it got to the stage where we just changed them on pre delivery and had the apprentice test them during slack times, 50% failure rate was not uncommon. The basics are the best point to start with, then the diagnosis kit, odds are it’s something simple most of the time. Nicely done, take care.

[@edsyphan3425]

I don’t understand why there wasn’t any fuel leaks or smell?

[@pebrede]

@@edsyphan3425 Thanks for observation. As with the KTM the fuel leakage from the split filter was internal in the tank. The only indication was low fuel pressure and loss of performance. The BMW KJetronic had a few interesting tricks. The fuel pressure regulator was on the injector rail and modulated by manifold pressure, with some skull duggery you could up the fuel pressure in the rail and get a richer mixture and more performance. The cold start enrichment (about 10% extra fuel) was controlled by a coolant temp sensor separate from the ECU temp sensor, the cold start enrichment modified the map as a part of the closed loop cycle until the coolant temp sensors cut the enrichment and open cycled the map. BUT If you were fully warmed up with the engine running and pressed the starter button the ECU denied the starter solenoid power but layed the cold start enrichment over the map so you got a rich power mixture out of it. Bosch did some sneaky things and told very few people.

[@edsyphan3425]

@@pebrede ok, didn’t notice it being the internal type. Seems a lot better than the near catastrophe I had on a 2009 BMW RT, the fittings were plastic and I had fuel dripping down on my header pipe.

Had an SH300 issue recently. Duff thermostat stuck closed - FFS- overheat, combined with bad injector spade connections, combined with a faulty, BRAND NEW, NGK spark plug that performed brighter than the sun - failed when installed.

You did a great job explaining. I reflashed my own bike, a Mash TT40. Bought an Aliexpress CB400SS exhaust and welded a bung in it. Ran sh*tty. Wouldn't pull above 3000rpm. Together with hud ecu flash and selfmade obd2 cable and tactrix open port plug and months of research i was prepaired for this. So i programmed an open loop system because the narrowband O2 sensor wil otherwise keep it too lean. Runs better now than original.

[@pkuudsk9927]

Nice job. Years ago I had a fuel pump that split like that. Just shows that it pay's to check all the basics first, and if you can't duplicate the problem DO NOT start throwing parts at it. My bandit 1200s right at the end of riding season here in Canada It started acting like fuel starvation intermittently. Checked petcock checked floats, seat needles jets. Just as I was about to install and try again, Why I don't know but I decided to check the TPS for OHMs and it failed open circuit on the 2 outer pins. I have owned this bike since new in 2001 and she has been dead reliable. So after 280k kms I can't bitch about it , basic Maintenace, adjust valves, oil changes forks included and that has been it. I don't think I will ever replace it with a EFI bike. I work on cars for a day job and see all the problems they have why the hell would I want that on my bike?

[@ShadowVonChadwick]

Thanks for sharing, that was time well spent watching. KTM most likely have installed a new throttle body and then realised they were other issues. Maybe not, depends on their local shop culture. But you saved Him at least five hundred quid. (OMG, Yes, it made sense 🙃) Cheers from Downunder.

There’s a handful of things it could of been. Any vacuum leak in the intake tract from the TB on, so manifold, evap or other hoses etc. Also any exhaust leak ahead of the oxygen/AF ratio sensor can cause a problem. If exhaust can leak out, oxygen can get in.

Just one observation..... Some ECUs don't reset long time fuel trim when you clear the codes (resetting ECU). Some do, some don't, i gues KTM ones do. In case they don't, only riding/driving will put long time fuel trim to normal value after ECU learns from new short fuel trim values that problem is solved (lean or rich condition).

[@SuperbikeSurgeryTV]

Just for clarification if anyone is reading for information. Clearing codes won't do anything to fuel trim numbers. Resetting the ECU will Zero out fuel trim numbers, (long and short term) or at least in every case I've ever done reset it has. It's kinda the point of the ECU Resetting procedure.
