    Re: KTM Duke 390 - Ownership Reviews and Experiences

    Any tips on adjusting slack on the chain when there's a huge difference between the tight and loose spots?

    While adjusting it yesterday, it was fine at some point and really loose at the other. Now, People say that we should adjust starting at the tightest spot but how does it exactly work?

    Do i find the tight spot and loosen it? But then my loose spot gets further loosened. And then if I tighten the loose spot, the tight spot gets tighter. What am I doing wrong?

      Then it's high time to change your chain sprocket kit

        I'm in the same situation as you...I adjust the slackness on the tightest spot. But the stock chain is of cheap quality, noisy and stretches way to easily. When it's time to replace the chain get the DID VX2 520 chain.

              Actually what chip faces is what everybody does. Almost all drive chains wear at a irregular rate, due to what's called run-out tolerances. Actually, the knack is not to tighten/loosen all the way from the tightest spot. You have to adjust just at the beginning of the tightest spot. When a chain/sprocket is worn, a slight loosening at the tight spot would eventually loosen up the loose part so much so that the entire adjustment has to be repeated again and again. Try adjusting the chain just at the beginning of the tightest spot and keep a tab on the wheel alignment itself.

              BTW, how many KMS has the bike actually clocked?

              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.


              THE END

                Duke 390 not starting, and then not idling

                Hi,
                After I parked my Duke 390 in Forum Value Mall yesterday, the bike seemed to being displaying this non-idling behaviour soon at the parking checkout counter, where it just stalled and took 3-4 ignition presses to start.

                Then at the mall exit it stalled and then wouldn't start. After a lot of pressing the ignition, trying to idle, and revving the engine, it started, but soon gave up the moment I left the throttle. This went on till all the way home and the only option was to never let it idle at all.

                I somehow managed to reach home. I'm thinking of the following possibilities:-

                1. The idle RPM was changed by mistake/ by a mischief monger.

                2. Some oil/water may have slipped into the fuel tank. (the fuel in the tank seemed one bar higher, but I didn't think much of it since the bars aren't exactly reliable) This also makes sense since the bike ran for like 100m properly, (using the fuel already in the pipe) and then started showing signs of trouble.

                What do you guys think I should do (in terms of personal checks or checks by technicians)?

                  Hey man,

                  The bike has just clocked 9000 km which is a shock to me! I service my brothers 390 too (he took it from me at around 12K) and till date it hasn't faced this issue. So what could be causing the newer bike to do this? I do pop an occasional wheelie during Sunday rides. Does that cause a lot of stress on the chain?

                    Better take the bike to SVC and do a thorough check up, you never know what you might find,🤔 that guy must have messed up with your bike😯, next time you see him kick his butt.😬

                      I don't think it's possible to manually fiddle with the idle rpm.
                      The idle rpm is controlled by the 'idle control stepper motor' which is located on the throttle body and this works along with the ecu/various sensors to maintain the right idle rpm. It could have conked out.
                      Another part that might have conked out is the throttle position sensor (which is again located at the throttle body).
                      Other stuff to look for are ignition coil, spark plug, battery terminal connections, fuse.
                      Also Inspect the throttle cable at both ends and see if you can spot anything obvious. Also check if the fuel filter is connected properly (take a peek under the tank)
                      Does the MIL warning light stay lit up on the console ?
                      Please head to the svc and let them check it out, and let them connect their diagnostic tool and debug it if necessary.

                        Immediately check the fuel . Take sample in a clean glass bottle by removing fuel tube from petcock and turning it on . Then do filter-paper test . If suspicious, remove tank , drain all fuel and clean the tank . Also check if exhaust pipe is clear .

                          no petcock on the duke. it's fi, at best one can remove the fuel filter but the fuel doesn't come out of the pipes connected to the tank(rather the fuel pump) on removing the fuel filter. the pump needs power to push the fuel out. and trying to play around with the tank in place is tricky due to very limited space (fuel filter is right under the tank)
                          one could remove the petrol from the filler area using a long pipe, but again i doubt if you could get a proper sample. only way is to dump out the entire contents and refill with known good fuel if you want to rule out bad fuel.

                            Oh , didn't know this Would have been better if there was some easy way to check a fuel sample directly from where it goes into the combustion-metering system ( Fi injectors ) . Because taking sample from top of the tank may not reveal the presence of water , for example ( water sinks in petrol ) . Any way fuel can be collected from where it comes out of the fuel-pump , say by opening the exit tube and momentarily turning on the ignition ?
                            I have seen this a few times at the Yamaha service here how fuel was contaminated with water , kerosene etc by frivolous miscreants . Even the service center had a hard time detecting it , found after a whole lot of parts opened and frustrations . They were at loss as how someone could get it into the tank .
                            Dismantling the tank and cleaning is laborious but if fuel contamination is suspected , whatever has to be done , has to be done

                              Just wondering, why and how would someone do that? If someone could open the filler cap which is locked, then he might as well take the bike out for a spin..

                                Hello,

                                How good are these tyres on Duke?

                                Michelin Pilot Street . **cheapest option, Is it better than MRF and comparable to below 2?

                                Pirelli Diablo Rosso II
                                Metzeler Sportec M5

                                I am planning to by a Dominar this week and swap the tyres as I am not confident with hard MRFs
