throttle

Hi, I just recently bought a rc390 2021 model. And it just hit 1200kms. And recently it started cutting out after 5krpm just all loss of power.(In all gears) any ideas what it could be ? Basicly useless to me right now as I need a daily for work thanks in advance !!

2017 RC 390 Long story short, I installed a PCV with WB2, K&N air filter with MT open air lid, straight mid pipe, cheap slip on with out baffle, and map from Rottweiler for open air box and comp exhaust. Bike will not stay running at idle, and struggles on all gears unless I’m wide open in 5th...

I am having a horrible fuel cut / AFR spike issue on gentle throttle off - throttle movements that I am in desperate need of help with. The bike is a 2017 model with the following mods: PCV rev xtend to 11,200 rev limit auto tune active on closed loop section (0%-60%, 0-7,500 rpm) - 13.5...

I am using my 2017 RC 390 for track. As the track day goes by, my front brake lever becomes spongy and the lever touches the throttle. I changed brake fluid to Motul 660 this morning in the hope that brake lever feel would get better. The feel is better, but if I put enough pressure I can get...

I am installing driven clip on. I am missing the pin on the throttle side that connects the start-stop switch to the clip on. Any body knows type of the pin and length and diameter of the pin. Can I get it from a hardware store? Also, is the pin on the clutch side switches the same as throttle?

I picked up a new 2017 last week. Build date December 2016. That's all that's available in Australia. My throttle was sticking and jumpy. A warranty item but half the fun is getting in and doing things yourself imo. Bit of a risk, just like riding on our roads :p My throttle is now smooth and...

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

Change throttle fly by wire from rc 8r to rc 390 ,possible? Someone did it?

Am I an idiot here? Is there no adjustment to adjust the free play in the throttle on the 2017? I know it's throttle by wire but many other bikes can adjust the play out of the throttle even when throttle by wire -- but I'm either an idiot and not seeing it, or they hid it *and* removed it...

is there a comparable one to this Lightweight Throttle Return Spring - Yamaha R3 - YamahaR3Racing.com for the KTM?

Hey guys, I managed to strip the throttle cable threading on the bottom of the engine start switchgear box. I was trying to tighten down the lock nut and ended up backing out the cable housing. Any ideas here? I'm tempted to just epoxy the elbow joint into the switchgear. There is a still a...

Anyone know if there is a quick, or shorter turn throttle for a 2017? They have them for the pre 2017's with the cable throttle, but now that they have moved to an electronic throttle I think it would need to be different. Thanks, Mike

I've recently bought a 2016 RC390 and am enjoying it immensely. My other bike is a Ducati Multistrada. Clearly, these are two different approaches to life on two wheels. I rode the Ducati from San Francisco to New Orleans last year. The RC on the other hand is my daily fun ride to nearly...

Do the fairings and the gas tank have to come off to replace throttle cable? I think I know the answer but just checking. d

I'm in need of a spare Throttle Position Sensor for a 2015 RC 390.(#90141070000) I'm looking to make it adjustable and would like to get one as a spare in case things dont work the way I want them to....has anyone here tried to do this yet?....looks to be pretty straight forward to modify to get...

I know its a little early to be asking this question, but I figured I'd get the gears turning. With the 2017 RC390 being ride by wire, will a quick throw throttle be possible? If not, do you think it would be possible to retro fit the throttle system to the cable setup? I'm not talking about an...

Hi All, I haven't been on here in a year-- trying to get out and actually ride the thing! I have one major complaint that I'm trying to track down the best solution to. When going from closed throttle and rolling on, there is a very sensitive turnover point where the engine goes from braking to...

Hello, it's me again. My dealer said he can't legally tell me how to do it but he said it's easy. On the cup bike, to get max HP he said he can have his tech reflash the ECU, about 1hr labor, $125 But I would need to take apart the throttle assembly to remove the throttle stop so I can twist all...
