    Need Help Bike shuts off at idle, and feels like it has two powerbands

    hi everyone, my bike recently startet to shut off in neutral (after a few minutes) at red lights and it accelerates weird in 3rd and 4th gear. It jerks forward in 3rd and 4th gear when i rev it past 7k rpm. I suspect it might be a clogged fuel filter, but i'm not really sure and just wanted to...

    Keyed Gas Cap Options?

    I see plenty of keyless options but I ride my bike in the city every day and there's no way I wouldn't keep it locked up. Keyless is convenient for the track but I feel like I'd just end up with an empty gas tank. Anyone have any ideas for a "nicer than stock" option? Mine is looking a bit...

    Failure to Start After First Service

    Hi everybody, I've encountered an issue recently that I've been trying to figure out for a while and I'm running out of ideas. I completed my first service on my 2018 RC390 about a week or so ago. Measured the valve clearances (3 out of spec: both intake, one exhaust), shimmed em to spec...

    Powercommander V vs. other fuel controllers

    I was wondering what's the best option for racing. I am leaning towards powercommander with quick shifter and wanted to see if somebody has experience with other fuel controllers and could compare it to powercommander.

    Hello, I am looking to fit a Datatool Uno immobiliser to my RC 390 2015 (saves loads on my insurance premium).

    Oversized Fuel Injector

    I'm a little lacking in my knowledge of fuel injectors so was hoping to get some information on it. I'm currently running a full Tyga exhaust with an open airbox + PCV AutoTune module. Given I've set my AFR to 13.2, I would assume you'd need a certain amount of fuel to meet that ratio. Why...

    Racing Fuel Cap for 2017 RC 390

    What are the options for racing fuel caps for 2017? I think the tank is different than 2015 an 2016 model, so Driven isn’t compatible with 2017. As of now, I was only able to find KTM poweparts racing fuel cap for 2017.

    Fuel Gauge

    Thought my fuel consumption was brilliant, seems the fuel gauge is permanently stuck on full! Anyone else had this and has anyone got a cure, looks like there is a float in the tank but that is dropping as fuel goes down? Thanks for your help.

    Simplifying Disassembly

    Looking for advice on how to simplify the process of removing fairings and fuel tank. Are aftermarket/race fairings faster to take off? Can quarter turn fasteners be adapted to this bike? Is there a fuel cap that comes off easier than the stock one with like 10 allen bolts on it? Any way to...
