    2017 RC390 Battery not charging

    My motorcycle died on track at a very high speed and I think it is due to the charging system failure. I have antigravity Lithium Ion battery that cuts off the power when the voltage drops below a threshold. I charged the battery and started the bike, the battery continues to drop the voltage...

    Fuse blowing and high coolant temp after service.

    Hey all. So here's the skinny. My frustration is beyond maxed out and I need help. I have a 2016 RC390 with just about 3K miles. It is a track only set up. The water pump gasket went out about two months ago and I got it fixed at the dealer under warranty. I took the bike to the track the...

    Engine Shutting Off

    I have about 600 miles on my 2017 RC 390. A couple of days ago the engine shut off in traffic in second gear with clutch pulled in, the bike started back when I release the clutch. Today, I just started the bike to warm and it shut off after a minute of idling. I was wondering if this is normal...

    PCV installed, now stalls :-(

    FIXED: PCV installed, now stalls :-( Installed a new PCV on my Duke today - everything went fine except I neglected to zip tie the O2 optimizer out of the way and the back cover on the black box melted a bit on the header pipe before I realized. I quickly moved it off, cleaned the header...

    Tyga Stainless Moto Maggot Exhaust

    Yesterday I mounted up my new Tyga exhaust. Once I got the stock exhaust (2 1/2 hr. battle) off it was pretty easy to install this exhaust. I think KTM built the bike around the stock exhaust! Anyway, new exhaust looks awesome and sounds good. I started it just for a minute or two as don't have...

    Blown countershaft seal

    I have a blown countershaft seal. Got very lucky. I spotted it before I took a corner with oily tires. Any other reports of blown countershaft seals? My chain was not over tightened, in fact it had started to loosen up a bit after the 600 mile service. Bike has 2000 miles on it.

    DO NOT start engine without sproket cover!

    Maybe this is common sense and I just missed out, somewhere. If so, I apologize if this seems stupid to anyone. Last weekend, I was doing an oil change and was also going to clean/lube the chain while everything was easily accessible. After doing the oil change, I started up the engine to let...

    new member from Colorado...

    I picked up my RC390 on 4/2/2015 (right when they first showed up at the dealer here). I have 650 miles on her now. I love this bike... such a little ripper. If anyone else is in the Denver area, let me know. Here she is... before all this rain started :(
