tank

I changed my radiator and removed the thermostat. When I refilled it with water wetter, it filled up pretty quickly with probably about half a liter in the radiator. I filled the about 0.3 liter in the compensating tank. After a few track days and races, I saw that my compensating tank is empty...

2016 RC390 For the longest time I wanted to eliminate the gray "Read your Owners Manual before riding the motorcycle" decal off the back of the gas tank cover. Well, about a week ago I got out the hair dryer and finally took that darn thing off. Well, now that it's off there is a faint (how do...

There's two lines that comes out of a the fuel tank. 1. One that shares a Y-connection with the coolant overflow. 2. One that goes into the charcoal canister that also has a Y-connection. Can I plug the 2nd line directly under the tank? I assuming the overflow/vent is the one shared is #1...

OK folks... at long last and much begging on my part with the Tyga Factory, we finally have a Keyless tank cap for the RC (and Duke) 390's! I expect this will mostly just appeal to racers, but it'll work on the street as well. You can find it here:Formula390 - Parts Cost is ~$56 and I have 6...

I installed the Rottweiler EVAP delete kit the other day. I had a quick question about closing off the small tube that goes from the charcoal canister to the gas tank. I noticed today, that when I went to fill my tank (it was still about 1/3 full) there was suction on the fuel cap when I opened...

Hey guys, is the tank vacuum sealed? i.e. if i pull the hoses will the gas leak? i am used to my R6 where it had a quick disconnect and no gas (well very little) would come out when i took it off. I hate that the RC does not have any quick disconnects down there given its "race ready" tag. So...

Introducing our first designed and developed in house product! The simple and subtle rear tank mount! No its not much and won't make 15% gains like our air tube but it does make life easier. I was tired of having to pull the fuel tank to clean my air filter so I made a fix, this bracket is that...

I ordered two of these, not realizing that they would not work with my tanks. The full holes in my tanks are not centred and these caps won’t work. If you have the tank with the perfectly centered hole it will work. I want 20$ plus shipping for each

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.

Seems lately that I have excessive pressure in the tank when I stop to fill up with gas. I've checked the vent hose and overflow hose all are clear and not kinked. I did notice that within the cap itself their seems to be vent or something. You can see a half moon rubber seal with a hole in it...

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...

Ok, so dropped a valve ordered a new engine, and got it in. Problem is the shop I had taken it to initially never re connected almost anything so I've had to figure it out on my own after I changed the motor. I have two coolant lines coming from the front overflow bottle. One is a drain/vent...

Random bits of info (or how not to make the same mistakes I did) This is just random bits of info I learned when I did this stuff: New radiator PowerTRONIC ECU JRi shock Emissions removal Some other miscellaneous crap The airbox cover has two tabs towards the back that slip into slots on...

I'm running a custom tank on my RC390 that has no way to run the stock fuel gauge so I want to trip the sensor to just read a full tank. With the sensor unplugged it reads totally empty, 0 miles left, and always reads low fuel with the warning light which I'd like to resolve. Does anyone know...

Working on an RC390 for a client and thought I'd throw up a few progress shots incase anyone was interested. This started as a like-new bike 2 months ago, stripped it down and made a new subframe, mid pipe to a Lossa Engineering muffler, modified an old Honda gas tank, made a faceplate/...

2016 KTM RC 390 for sale in North Carolina. I purchased this bike new from Garcia Moto here in Raleigh NC last August. It only has 788 miles and has had the break in oil change performed. I have installed a fender eliminator that uses the factory lights. I have also installed a SW-MOTECH tank...

New to this forum, hey everyone! I'm just starting a custom RC390 for a client and this is the first FI KTM I've messed with, so I am looking for some specs on the fuel delivery system. I'm not running the stock tank and I can't graft the pump assembly into the custom tank due to its size and...

First post on this forum, hey everyone! I'm just starting a custom RC390 for a client and this is the first FI KTM I've messed with, so I am looking for some specs on the fuel delivery system. I'm not running the stock tank and I can't graft the pump assembly into the custom tank due to its...

I recently got this '15 RC390 and it has been working great overall except for this one issue. When the bike is cold, it starts perfectly fine. After it's running, if I start riding before it's fully warm, it has a tendency to stall and not want to restart. After searching around on the...

Alright, so first off, this is mine and my wife's opinion on this, second, I love this bike in terms of power and getting through traffic. Now well comes the sad part and I want anyone and everyones input on this. So, we got the bike back in April of '16, with a one year warranty from factory...
