Anyone running a standalone quick shift like HM? If so, have you experienced fuel integrated systems as well? Seeking the pros/cons!

Hey all, I've had my RC for just under a month now, it's a '17, and today I noticed it was leaking fuel. I started to tear it apart and found it leaking right under the ECU plate. If I lift it a little it comes out more. My dealer is telling me I can void my warranty by doing this myself but if...

Help needed from expert. Suddenly my Rc390 refuses to start. When I’m turning on the key there is no sound of fuel injector nor the engine/self start is cranking. Horn/indicators/dipper light working fine. Display showing low fuel and hi coolant temperature though there is enough fuel and the...

I'm running a custom tank on my RC390 that has no way to run the stock fuel gauge so I want to trip the sensor to just read a full tank. With the sensor unplugged it reads totally empty, 0 miles left, and always reads low fuel with the warning light which I'd like to resolve. Does anyone know...

I'm running an aftermarket tank on a custom RC390 with an external adjustable fuel pump and regulator. I'm running the pressure at 50psi right now because I had read that was stock but I just stumbled upon something that said 2.7 bar which equates to about 39psi. So I was hoping someone on here...

I started bike for first time in a few weeks and instead of the whining noise the fuel pump makes after turning ignition on, it made a noise like it was having trouble turning. The battery was low on power. I put a new battery in, but the bike will not start. I do not believe the pump is priming...

Looking to purchase an exhaust for my girlfriends 16' duke 390. Werkes is preferred as Ive had them on my Ducati and now on my FZ, but will consider other options, Fuel management is also under my WTB. Just unsure of the exact route I want to go. Thanks!

Hi All, I take my RC out every couple days and would like to know if it would be okay to run either RACE FUEL available locally at 11 bucks per gal or go with a local Ma and Pa non ethanol 92 octane at the country market. Please note cost is not a factor.. this bike get phenomenal fuel mileage...

First long(ish) ride today, over a very good road through the Monashee mountains. Absolutely loving the RC! But...seems every time I glance down, the red "shift" light is flashing at me! Anyone else with this problem? :p Plus, what's up with the "Low Fuel" display? Comes on, says I have 57...

Working on an RC390 for a client and thought I'd throw up a few progress shots incase anyone was interested. This started as a like-new bike 2 months ago, stripped it down and made a new subframe, mid pipe to a Lossa Engineering muffler, modified an old Honda gas tank, made a faceplate/...

I'm ashamed to say that after attempting to install a PCV on my RC390, I have had trouble with reinstalling the left fairing and fuel tank. The left fairing has a black cylinder that needs a hose connection but I can't seem to locate it. I only have three hoses that all go to the fuel tank, so...

Another satisfied owner of the Baijaj RC390, yes its not even up to the janitor at KTM's standards. Dual yoshi full exhaust, Bazzaz fuel controller installed. Overheating issues like everyone else. 12k miles was on highway cruising @ 65 and it died. I almost died also while cutting over 3 lanes...

Hey guys I searched through the forum before posting this to help streamline this tedious process. 2015 KTM RC390 Dual Yoshi exhaust full system, Bazzazz fuel controller installed. Ive had issues throughout the ownership of this bike including overheating, vibrations at low RPM and other small...

I was trying to figure out what next to do to the bike to lose weight and I thought of a new product idea. Plastic or Carbon Fiber Fuel Tank. My Aprilia has a plastic tank and so long as you use no ethanol fuel its no problem. Here in Tennessee no ethanol is available at many locations.

I have a '15 RC and have a question about optimal fueling. I am not going to do any pipe or airbox mods as I am not looking to increase noise or horsepower or even change the torque curve. I have read a lot about the bikes running lean and think I understand the socio-political reasons for that...

The manual says the gas tank holds about tel litres of gas. On my bike the low fuel warning goes off at the last wedge of the gauge and the display shows about 50 .km to go on reserve. When I fill it to the top at this point it only takes about 6.5 litres? That means there should be 3.5 left in...

We just stocked up on Driven fuel caps for both 390s, because honestly, they're fantastic. Perfect fitment, easy use, lighter, and super sleek. www.mnnthbx.com

I was searching Ebay for a little bling for my RC 390 when I came across this: Orange Laser Fuel Gas Tank Keyless Cap for KTM RC 200 390 | eBay Does anybody have any experience with these, not necessarily this vendor (picked at random among several suppliers all selling what appears to be the...

. So now that the PCV is installed. it was time to install the Dyno Jet Wideband Commander 2 ( WBC2 or WB2) p.n. 15-7023x........ so we could have more Control over the Fuel map on the bike. As many of you know the KTM 390 has a difficult ECU that doesn't allow closed loop to be altered...
