    First Big Crash On The KTM RC390

    So the inevitable happened and I took a little trip through the dirt with the rubber side up at about 70mph. I'm happy to say the bike faired pretty well! Not the greatest way to start off my second season of racing but an entertaining one nonetheless. Check out the sneak peek below!

I still need to take a more thorough look but for the most part my frame sliders did their job. Current damage total is about $140. Below is a little sneak peek of the crash. Is anyone else racing or tracking their KTM and if you've had a crash did your frame sliders bend your chassis?
      There have been cases of chassis bending due to sliders on many motorcycles, so that's a definite yes. So far, at least in this thread I haven't come across any bent chassis due to a frame slider. But, given the chances, the frame slider transferring the brunt of the impact directly to the chassis and the slider mounting poings on most bikes being at odd ends, the chances of the frame itself contorting can happen given the wrong circumstances.

      Cheers!

      Once upon a time, a guy asked a girl 'Will you marry me?'
      The girl said, 'NO!'


      And the guy lived happily ever after and rode motorcycles and watched sport on a big screen TV, went fishing and surfing, and played golf a lot, and drank beer and scotch and had tons of money in the bank and left the toilet seat up and farted whenever he wanted.

        I think, type of frame plays an important role in such bends.

        Old diamond frames have sturdy construction and such sliders sit on a sturdy frame will not cause damage to the bike.

        How ever the modern trellis frames are much lighter with many welded joints. Any sudden impact on one joint and impacting it will have major impact on frame because, all joints are stress members. Like a chain, one link breaks, whole chain breaks. This is the reason why we haven’t seen much cases here.

          I have clocked 49k kms and now the oil is being eaten up by engine within some 300 kms. I think pistons gone. But i cannot see any smoke from the exhaust. Has anyone faced some issues?

            Yes I have tried the thing you said but that is not something I would usually do on regular basis and its not a permanent fix to me. Just need to replace the stock bulbs with something better available aftermarket. The idea is to get a better spread and brightness than the stock setup.
            You should try HID.

              Re: KTM RC 390 Ownership Experience

              Having some issues after exactly 2 years and 7500 kms on the ODO:
              1. Phut-phut sound while decelerating still present ever since purchase.
              2. Issues with starting the bike at a signal when the engine is significantly warm.Sometimes the bike shuts down abruptly when slotted to 1st gear from neutral right after ignition. FI never cleaned but additives used to clean it.
              3. Bike has some cold start issues sometimes, God knows why would that happen on an RC.
              4. What tools (other than paddock stand) are required for adjusting chain at home?

                Issue number 1: Might be related to chain slack.

                Issue number 2: Might be related to the side stand sensor.

                  Phut phut sound is coming from the exhaust.
                  Will check the side stand sensor.

                    Start off with a compression check on preferably a cold engine and see if it's according to spec, that's one. Dry or wet both. Secondly, smoke can come during riding or the burning can happen slowly causing blue smoke, which means engine oil is burning albeit at a lower rate. Keep us posted on what the SVC has to say.

                    Phut phut or the so called exhaust backfire happens on almost most of the bikes, it primarily happens when the engine runs a little leaner, (i.e fuel mixture) more pronounced on carbs than FI's. Point number two, as our member suggested, check your side stand sensor and clean it if you find it's all gummed up due to chain lube or muck. If the magnet doesn't have a clear contact, the side stand sensors triggers the bike to stall. Though 7.5 is pretty much low on the odo, cold start issues can pop up then and there and idling and fueling all depends on the quality of the fuel used. Fourth point, you can get paddock stand or a roller type that goes under the wheel from Grand Pitstop (check their FB page) for easy chain maintenance tools.

                      I had a camshaft issue i changed it about a 1200 kms. Can that affect anything? I mean camshaft in above the valves. Can not properly fitted camshaft cause anything such?

                        As long as you don't hear any crazy sounds from inside the head, on top of the engine, your camshaft sounds good. As there is nothing but timing marks associated with camshafts. How well they are defect free is another topic altogether, but your camshaft shouldn't be the culprit at least from what you've laid out.

                          another possibility is valve stem seals gone. it's not always piston/block issues.
                          are you sure there are no oil leaks? Remove the belly pan and check.

                          can you check on a cold start if there is any smoke ?

                            I did check cold starts, there is no smoke! And yes there is oil on the engine everywhere but svc will say that its normal in every bike!

                              And no, it isn't normal to say the least. Engine oil spewed all over the engine can be due to failed gaskets, O rings and what not. First off, start with valve cover gasket, it's always been one of the Achilles' Heel and next comes the oil filter O ring which is a another miscreant that causes oil to weep. All these leaks leave residue over time and you can see black muck covered over them and is easy to spot. Give your motorcycle a thorough wash, and before that snap some pictures of your engine compartment and post them here, would help us analyze, at least visually the severity of the leak.
