Anyone know if KTM is still having issues with warped heads? I have paid much attention to this since 2017 or 2018, just want to be prepared. Thanks, Mike

I have a 2017 RC390 I have a race tech shock and race tech cartridges in the forks. Anyone know if I can swap suspensions between a 2017 and a 2022? I would also like to know what else may be swappable I have some other race/track bits on my 2017, it would be nice not to have to re-purchase...

As you may have read in a previous thread I installed a 2016 woodcraft ignition delete on my 2017 RC and burned up the ecu and wiring harness, I purchased a used ecu and wiring harness from a wrecked bike and installed it. I think I have everything connected correctly, but who knows, it's not...

I'm hoping someone out there has their fairings off or even better the engine out of the frame and would be willing to take a bunch of pictures of the wiring harness routing and connections, and either post or send them to me? I had to replace mine and I'm having some issues. I took photos, but...

As some of may have seen in other posts I need to replace my wire harness. I bought a used one that's supposed to be from a 2017, but it's at least a bit different than whats on my bike. Here are some pics, sorry for the ugly foot in one of them :). This is from the original one 4 cables in...

It looks like the ECU has a plastic cover that needs to be removed prior to disconnecting it. I don't see any obvious way of removing it, and before I break something else :) Is anyone able to describe, or have a link to a walk through for disconnecting the ECU? Thanks, Mike

Well I fried my ECU. Has anyone tried any of the after market ones? Any recommendations? Thanks, Mike

I attempted to install the ignition eliminator today and I think I may have fried the ecu. 2017 RC390 I have a PCV in case that effects things. Anyway I attempted to hook it up and when I made the last connection there was a pop and smoke started coming from under the fuel tank cover. I removed...

This may be a little odd as I'm not sure even how to ask the question correctly. First off I'll say, "I understand set up is always a compromise, if I set gearing to optimize one part of a track, it may detract from another". I'm a club racer and basically all my riding is done at one track. I...

I'm seeing 47mm, 50mm, and 51mm anyone know which is correct? I measured and it looks like 50, but it wouldn't be hard to be off by 1 mm. It's for a 2017, but I don't think it matters. Thanks, Mike

Looking to get wood craft clip ons that will be around the same height as the current bars. Anyone know if I should get 1 or 2 inch risers? Thanks, Mike

I was thinking about doing a track day weekend at thunder hill west. It's about an 860 mile trip for me one way, and will probably require using a couple of vacation days. I know it's supposed to be one of if not the best tracks in the country. Having never been there though, I don't know how...

I am going to be pulling out my water pump and replacing all the gaskets and seals. While hunting around for info I've seen mention of re-loctiting a nut, adding a lock washer and maybe some other things. I did not see any write ups on what things should be done to help improve the water pump...

Would someone be able to tell me where to find the oil pressure sensor? Thanks, Mike

Hey guys, I'm at the track and the low oil pressure warning is coming on. Oil level is good any other common issues I should check? Thanks, Mike

My throttle has gotten a bit sticky. I haven't played with a fly by wire throttle before, and the service manual doesn't seem to have much info. Do I need to take the hole thing apart to clean and lubricate it? Any advice? Thanks, mike

I ride a 2017, just wondering if there's a caliper upgrade avalable?

I'm going to a 47 tooth rear sprocket, anyone know how much longer a chain I'll need? Thanks, Mike

So, I picked a new stator cover from the local KTM dealer. Turns out you need bushings as well, which they don't have and will take 4 days to get. The old ones don't seem like they will come out. Anyone know where I might find the correct size bushings in the Phoenix area, and what I should...

I'm fine not a scratch. So I low sided over the weekend and ground a hole in my stator cover. I pulled the cover, and in the case I found a short 8mm bolt, but there are no bolt missing from that side of the engine that I can see. I also found a valve shim on the floor next to the bike. It's...
