CR23 Started a new thread Identify Right Firk Internal Cartridge
4/29/2026 4:46pm Can anyone tell me what model Austrian bike the darker gray internal came from? I got it with some spare parts. The lighter gold cartridge is from my 24 350sxf. Can’t find any in OEM fish that show a bottoming cone like the gray. Any idea?

CR23 Added a reply to 2024 350sxf Slave Cylinder Piston
1/22/2026 4:18am By plunger, are you talking about the slave piston? The first pic is the piston with only the o ring installed. The seal, or boot, or bellow, or whatever its called is to the left. small inner diameter fits in the groove where the screwdriver tip is. Is that what you were asking for?

1/20/2026 6:55am Someone mentioned hot water, haven't tried, just warmed with a heat gun slightly. I have an older 2020 version of this piston and its a different design. The area where the ID of the seal slips in is actually fully raised above the other area. There's no "recessed grove" (where the screwdriver is sticking) if that makes sense. This designed...

1/19/2026 4:09pm Anyone have a method to replace the “boot” seal on the piston? I can’t get it to slip into the grooved slot for the inside hole. I tried heating it some and wetting it with brake fluid. It has to be stretched to fit, but I can’t get it started. Is there a special tool or something. Magic? Voodoo? WTH...

CR23 Added a reply to 2024 Ktm 350 sxf stock remap vs vortex ecu
1/15/2026 12:51pm I had an 18 & 19 350sxf. Tried Tokyo Mods,TZR, and eventually bought the Vortex from TD. I'm sea level, so that might have some impact..?...but I will say the Vortex was a big disappointment especially for $1,100. The reflash made a small, good, noticeable change when paired with a vented airbox and screenless air filter. I questioned if the...

10/13/2025 4:55am 2024 with 25 OEM plastic kit and Rival "stock" designed graphics. Turned out great. OEM kit was a bit more $, but quality and fit are perfect.

9/25/2025 6:37am Searched but didn't see a clear answer. Anyone know if 2025 350sxf plastic will bolt on to a 23/24? Googled it and found conflicting answers. Anyone done it? The shroud shapes look a bit different in pics. Thanks!

CR23 Added a reply to K-tech single fork conversion
7/15/2025 10:31am I went K-Tech route on my 19 350. I had a revalved air setup including midvalve and other stuff. Worked significantly better than stock. I converted to K-tech and found it noticeably better than the modified air. Recently got a local tuner to revalve while servicing the forks. He said he'd done lots of single spring revalves. He missed the...

12/31/2024 5:33am Just pulled one off after less than 1/2 season. It felt like it developed a burr internal to the push button area. Couldn't fix it. Wouldn't engage or release smoothly. Started hanging up and dragging my fork protector (ktm) down. Also pulled my dust wiper with it. Bit the bullet and ordered a WC. Its well built and magnetic to...
CR23 Added a reply to 2018 FC250/350sxf ECU Tuning
9/13/2024 6:39am I had Tokyo Mods do my 18 sxf, stock motor with slip on. For a lot less money, it turned out just as good as my full TD Vortex for my 19. If I had it to do over, I'd pass on the Vortex.
CR23 Started a new thread Vortex Setting Question
8/27/2024 10:22am 2019 350sxf with TD Vortex. What should I expect from a map labeled : Map #6 = " Endurocross most agressive dirtbike mag test" when I compare it to #7 ( Map #6 -1 degree) , Map #8 (Map #6 -2 degrees), and Map #9 (Map #6 -3 degrees). Curious as to what these "should" feel like. PS: I can...

8/16/2024 5:45am I saw earlier in the thread where someone bumped up the TPS voltage. Has anyone with a Vortex, (or remapped ECU) adjusted their TPS? I have reset my '19 to factory spec's. (slide adjusted to the bottom and set to .4 volts) It now runs around .56 to .58 at ~2000 rpm. Is there any reason to adjust further? I...
CR23 Added a reply to 350sxf Fuel System Troubleshooting
8/2/2024 2:07pm OK. Due to inner child and wanting to ride tomorrow....I put in a new fuel filter and spark plug at the same time. Buttoned it up. Runs like a champ! IMO, I'm leaning more toward the spark plug. It wasn't cracked. Although the fuel filter was cloudy, it was full of fuel and I could blow air through it. Maybe...

8/1/2024 12:55pm No, i haven' touched the injector. Is there a way to test it? Battery on the bench? Just took the fuel pump out of the tank. Its a 6 year old bike, but sat for a few years in my friends shop. The filter didn't seem to be cracked. It does look dark, so not sure how dirty it really...

8/1/2024 10:30am Hope someone can offer some help. Gets expensive just changing out parts! 2019 350sxf , 57 hours, valves checked and in spec, clean air filter, clean fuel filter (small one), fresh gas every ride. No glaring problems. Two rides ago, bike coughed and died, randomly while I was riding, twice. Restarted and ran the rest of the day. This past...

CR23 Added a reply to AER air to spring conversion kits
7/10/2024 4:49am Either mine came with a sheet or I found it on their web. It showed 380 for the spring side. I've read where some end up at 400. As for the dampening side, I believe the KTM spec is 220 +/- 20. The tuner I used for a revalve told me he goes up to 280. Before K-Tech, I had...
CR23 Added a reply to AER air to spring conversion kits
7/9/2024 10:41am I did the K-Tech. No noise, works really well. Is your spring preloaded any? Mine's about 6mm, so its not moving around. Still trying to figure out how to balance the oil between it and the damper side. What levels are you running?
