oil

The more I dig up on the 17/18 390 engines the less I think I want another one. WP seals, coolant swelling paper oil filters and catastrophic engine failures? Might be tied to the head gaskets too? Geez. So, before I give up, are there any SS screen style oil filters for this engine? I...

I have a 2017 KTM RC 390 and had ridden it about 500 miles; just realized that the oil is on the lower side (picture attached). I ran the engine for a while, waited for a minute, and the bike was on rear stand. I was wondering if running on this much oil would have caused any damage. Would it...

Is it better to put fully synthetic oil at 620 miles or continue with KTM recommended Motorex semi-synethic? Which oil do you use?

Is it correct that you have to remove and disassemble the forks to replace the fork oil? Would it be possible to drill and tap a fork oil drain bolt?

I've had my 2017 RC390 for a few months now and am already having my first issue. I am seeing the "Low Oil Pressure" light during the bikes warm-up. It's a bit strange because the light will always come on while the bike is warming up, but once it gets to operating temperature, the light will...

Have my first service coming up and I'm trying to save a little money by changing the oil in myself. I was thinking of getting this kit https://www.ktm-parts.com/90238015010KIT.html for 50 bucks but I don't know.... the dealer says they charge me $70 for an oil change so that's a whopping $20...

Hi, I have recently changed from motorex to motul and I have noticed that bike started consuming the oil. In the last 2000km i had to put 300ml of oil. Has anybody else noticed it?

I was at the shop yesterday for some oil Picked up some 300V and when i got home realized i had grabbed 10W40. what weight does everyone run? 15W50? anyone run 10W40? what oil do people run (for racing)? etc! 300V is crazy expensive! lol. -Jason

Hi guys, So, background: 2015 rc390, new to me at 12k kms (Canadian) last winter. Then proceeded to build it into a race/track bike with the following: - PCV (chad map) - akra flash - shift kit - custom exhaust - all the other usual stuff not relevant for this discussion (see pic) Last...

Hi, I'm having difficulty in engaging gear during WOT . I'm not able to upshift when my rpm is above 9k. Anyone experienced this issue before? I thought it might be the engine oil (Motorex about 2k km) and i just changed it to Motul 300V 15W50 but the problem is still there. Thanks.

This is my engine level after first servicing oil change. it barely hitting minimum level is it normal guys? or i they didn't change oil? I have attached image please help me out.

So I missed the deadline for winterizing my bike when the tomatoes hit the first frost. Now all the tomatoes at the supermarket taste like water packets -- Yuck! Today in Portland Oregon there was a chance to ride! 50 and cloudy!!! I bought Dewault socket sets and allen sets from home depot 0oo...

Hello Guys, Recently, I have a problem with the oil pressure. Last week, I rode my RC390 (2015) for 150 km, and went to the gas station to fill up the tank. After filling, I rode for 1~2 minutes, and the low oil pressure showed. (My bike's odo is 19000 km) I turned off, and re-started the...

Hello, I am trying to figure out what color scheme to go with for my race fairings. I've got a theme in mind, and i'm torn between two colors, a baby blue-ish color, or a turquoise color. My theme's Gulf Oil livery. I think it would match very well with the frame of the bike. So which color...

Hi all, I'm reading this forum for several weeks. First, i want to say thanks to all the forum members for shearing their knowladge. I would like to order my 2015 RC, front and rear suspensions from Mupo SRL. (Italian brand) Thay offer only for the Duke390, front and rear. Can i order these...

I see a few threads on this but I want to get the correct answer. I see people putting anywhere from 400ml-460ml (recommended) in each fork leg. I also know that setting the oil LEVEL is more accurate. Whats the correct oil height from the top, compressed, springs out?

Well i'm back with another problem... I got my bike back from my mechanic a few days ago and had a ton of work done on the bike. Including rocker cover gasket and a general service. When I pulled up at home after a totally normal ride the bike started to spew out a ice-coffee coloured liquid...

New 2015 RC 390 owner. Bought the bike from a buddy I grew up with. He bought it brand new in WA state. Clocked only 970 miles on the bike before selling it to me with all his gear, got it for a great price so I couldn't pass it up. First endeavor in a real bike, should be fun. I'm 34, big...

New here and recently changed the oil/filter on my bike. I'm exactly at 1.75L and the oil level in the window is still at the bottom marking. Should I add more oil until it's in the middle or just leave it knowing I have the spec amount of oil in it? Thanks

I'm away from home so don't have access to my FSM. Anyway, I've got an oil leak coming from the two rubber plugs/connectors on the flywheel side just above that chrome cap. Any ideas what that could be? I thought the flywheel side/electrics would be dry? I'd post a pic but not sure how on a...
