Hey! Couldn't find a thread with my issue, as its slightly different from all the other "engine cuts out" threads. I recently blew my head gasket at a track day, so pulled my motor to change it and do my valve clearances all in one go. I had some issues getting the oil scraper ring back in the...

Bent a valve and cam chain let loose in my 15’ cup bike. Need a motor. Are the 15’-18’ motors all generally the same ?

Bought my 390 about 3.5(?) years ago, warranty expired around 3 yrs ago, only 7k miles on the clock and the motor blew up, electric fan failed with warranty repair in the first 90 miles among several other warranty fixes but anyway... Coolant in the combustion chamber and a little in the oil...

Hello everyone. Just joined the group today. I'm looking for a replacement engine on my 390. Any suggestions out there? also looking for recommendations on service/ repair shops. Thanks!

Looks like my woes continue. After a hard ride on the way to work yesterday, I noticed a the sound of baseball cards on a bicycle spoke coming from my motor. I have a full Yoshi exhaust, so for the noise to be loud enough to be heard over the exhaust, I knew there was an issue. Took the...

Hey guys, I am supposed to go racing on the 13th-14th of April, unfortunately my motor went this week. Anyone have a spare they'd be willing to sell? - Josh

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...

Hello Everyone, Thank you for checking out my introduction. I'm JB, and will soon be a proud new owner of 2016 RC 390 Cup bike. Although this will be my first KTM, I am not a stranger to the brand. 1) What can you share with me about the 390 Cup that I can't read about on the internet? 2)...

Hey, wondering what everyone does for winter maintenance on the RC and any recommendations. last year was my first year racing one.. on my R6 i would do valves and clean it up, + refresh the forks / shock, but thats about it. Anything else i should be doing on the RC? I am planning on doing...

After two years of development and saving up for parts and graphics I finally finished my project and it was time to put both the bike and my skills to the test! The bike is a 2015 RC390 and it clocked in at 42.68hp on the dyno with 26ft/lb in torque. I'm curious to hear what kind of HP numbers...

Extreme High quality. These should be ready in about a month and we have the first 10 exclusive to us. We would love...

To start off, I've got about 1300 miles and counting on my RC390. I live near San Diego, and regularly like to go hit up Palomar mountain and the surrounding areas that are in the 3000-6000 foot in elevation range. When I first got my bike, I took it to the top of Palomar (6000ft) and it puked...

Like this (Link removed due to Copy write Rules ) which is for the 2013 390 Duke. That does have things like adjusting valve clearances, motor dis-assembly, etc although in not as much detail as a Clymer or Haynes manual.

Started my first service interval work today... oil change was all I accomplished before I retreated back inside to the AC... but not before I got a bit of a surprise in one of the screens. My motor has worms! ;) I'm honestly not surprised, and expected to see more gasket bits, chips, and...
