    Guys I am facing this issue of intermittent ignition failure. This mostly happens after brief stops at traffic signals, bike just refuses to start. If I keep on cranking, the battery seems to drain and then if I wait for a few minutes and try, surprisingly it starts.
    Today morning I tested battery with multimeter. In cold condition battery voltage was 12.65v. When I cranked it, the load test voltage was 10v but it didn’t start. As I kept on cranking(around 15 attempts) the load test voltage kept on decreasing and reached 6v in last attempt. Mind you that I turned off ignition in between and waited.
    Then after a few minutes I again tried and it started. Battery voltage at idle was 14.1v.
    Is this an issue with battery or something else ? I am using 3.5 years old exide xltz7 battery.

    Another issue I am facing is that when I ride in traffic where brakes are frequently used, the rear wheel tends to jam.
    Once it happened that rear brake failed and the brake lever was going all the way down without any resistance.
    I too faced similar problem just few days ago,i was skeptical about my spark plug or fuel pump gone bad as after turning on the iginition i couldnt notice any vibration that fuel pump motor generates,on getting it checked at svc they found it was a relay that wasnt working,costed me around 110rs plus 80rs labour..its a small fuse like part with omron written on it.

      Thanks [MENTION=29396]shiv[/MENTION] and [MENTION=99741]Moshca[/MENTION] for your inputs. I think the problem is with relay only. Just now it happened again, I observed that when I turn on the ignition the fuel pump was not priming. After switching ignition key to on and off multiple times, I finally heard the sound of pump and then the bike started in one crank.
      Most probably it is the faulty relay. I have one spare relay which I will install tomorrow morning and it should resolve the issue.

        Too low brake fluid and excessive air will cause the pedal to travel all the way down. Rebleeding of the brake system is necessary. Also, extremely worn out pad would cause the piston to heat up in in turn boil the brake fluid which would mean brakes locking and jamming. It's time to overhaul your rear brake caliper; bleed it properly, with new fluid and also new piston seals would help. Yours is an ABS or non-ABS?

        Cheers!

        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.

          Pads are nearing the end of life so I will replace them along with fluid and bleed it. Mine is non ABS.

          PS: Ignition issue is resolved by replacing fuel pump relay.

            Just as I suspected. Replace your pads, clean the caliper innards thoroughly, grease the slider pins.

              Hey guys, I've officially taken the plunge into the unknown quite literally as the tagline of the Honda is [emoji28]. Purchased the aracer MiniRC 5 for 15k , without shipping which won't be needed cause I have a aunt in Thailand bringing it in by next month. It's also 3k cheaper the most readily available ecu for bikes on the market, powertronics.

              I can also say I'm extremely impressed by engine ice, which is keeping my bike cool even in stop and go traffic surprisingly and the liqui moly 10w 40 street is holding up really well after a bit of sitting in the higher revs. Will mostly stick to this oil, and will change it right before changing the ecu and sort out some front end niggles and also changing the bottom t stem and may the top of if it's bent and adding tapper roled bearings in the bottom which I can say has made the steering light and easy .Will make it even more compliant. Soo that's that will give a update at 60k km with the new ecu [emoji16]. Also I have changed my clutch set at 51k as precaution , old clutch set had about 30% life left , didn't wanna take a risk because was doing a short trip of Chennai to blore.

                    Hi fellow riders, I'm new to this forum and need bit of advice on my newly bought used cbr250 ABS gray matte with orange, 2018 model, 7500km

                    As per service bills, first owner had replaced the rear brake pads at 4000km only, now mechanic told me that rear brake pads are due for replacement again @8000km

                    Do the rear brake pads of cbr250 ABS require so frequent replacement or is that a fault with the brake unit? What should I be looking out for. Any help is appreciated.

                      I am indeed surprised to know this. For the first time ever, ABS brake pads requiring pad replacement in less than 8k, I am shell shocked. "No", there is clearly something wrong with the caliper. Either, it's getting stuck or the dependence is too much on the rear brakes, yet still, it should easily last more than 18k solid, the rear and the front combined. First off, what was cause was reasoned as the replacement of rear brake pads? Did you check the old brake pads personally? Sometimes, SVCs loot in the name of consumables such as brake pads, fluids and what not. Unless we have a clear picture (actual picture) of the old brake pad, it's hard to guesstimate. Secondly, how good is your rear braking, is it affected negatively as such, or it's the same as usual i.e. when you purchased the vehicle? I am suspecting a foul play here by the SVC guys, but again, without any evidence backing it, I can very much be proven wrong.

                      If you can, do post a picture of the rear brake pad that's due for replacement.

                      Cheers!

                        VJ, thanks a lot for your reply and advise. The rear brake bite is bit poor since the time I laid my hands on the bike but it does its job. First owner had replaced the rear brake pad at SVC; I got it checked from outside mechanic because I've less faith in SVC. The rear brake was not opened but the mechanic told so just by looking at the unit that it might not last more than 2 months.

                        I'm attaching few pictures of rear brake unit, not sure whether it's helpful to make a guess. Sorry about the mud and dirt on bike due to rains in Pune.

                          Thank you for the photos. That's a goner indeed. The brakes will be totally bare to the metal after a couple of thousand KMS, or a couple of months, as you trusty local mech has advised. My suggestion would be to replace the pads outside SVC, in front of you, and let's see how it unfolds.
                          Good luck..

                              Will an H4 LED headlight unit (like a Cyclops or Night Eye) fit into the socket for those little lights on the side of the main headlight? I dont know if theyre DRLs or what? That'd end up with three separate headlight units in the front end of the bike. Yeah I know its a crazy idea, but is it possible?

                                The Pictures confirm that the Rear Brake pad is indeed a bit worn...it is worn more than 60% . Before changing pads, Please do check if the floating caliper is jamming and also check free movement of the Brake Pistons in the Caliper ....either one of them is stuck or there is a tendency for the rider to rest his foot on the foot brake pedal causing mild application of brake all the time.
