    it seems that HH ZMR has hit a road block. the way things are in our country things can be brushed under the carpet at will. when HH is delivering all its other bikes as usual to its dealers what has happened to ZMR ? it may have to do with a faulty fuel injection system as there are no other major changes apart from oil cooled engine and grs susp. the highly advanced fuel injection system may have hit a dead stop with the poor fuel quality in india ?

    we may never know.... but the truth is the bikes are not coming.

      As with any new bike or car, there is bound to be an initial rush and hence delay in bookings. I don't believe the delay has to do with FI units - did you read this somewhere in the media?

        sorry no.. its just the excuses put forth by the dealers for not delivering the ZMR withing a reasonable time. 2 months has passed it may be worthwhile to note there is hardly any activity about this bike on any forums.

        i think i may not be way off the mark with my soothsayer type conclusion on the ZMR, but i have ruled our ZMR for me.

          That's quite an informative discussion. It is really helping me to make my decision for my bike!

            Rahul if one bike doesn't have a kicker or one does, it would be difficult to start the engine ?

            Indian bikes doesn't have a kicker
            P220 DTS-FI(If in production)
            Karizma ZMR
            CBF Stunner PGM-FI
            R-15
            & Ninja 250 R(Does it comes under Indian bike?)

            Indian bikes have kicker
            Glamour FI(if in production)
            RTR 160 FI
            Classic 500 FI

            If a bike doesn't have a kicker when the battery fails, when you try to push-start it it's not starting(as you said)

            When a bike have a kicker when the battery fails, When you try to start the engine with kicker will it start ? If it doesn't start in-case it have a kicker,What would be the result ?

            I had this doubt for a quite long time.

The engine develops barely half the power, cuts out above a certain RPM and guzzles fuel like a drunk with his tail on fire. Just imagine this in a given scenario for our bikes: You are descending Tanglang La and the bike goes into 'limp-home' mode. By the time you get to Mandi or Chandigarh or Delhi where you can get it fixed, you'll really be aware of what 'limping' is all about.
                limp hole mode!!!!! this scenerio is bound to happen in the fi engine!!!! carb engines wont be facing this problem at all!!! am i right?????

                      the problem in the delay of the bikes was that of the cooling cylinder!!! it had a vertical cylinder put in it which led to less efficiency of cooling!!! which in turn over heated the engine!!! (dont no much about this but this is what i read on this forum when i asked for the problems in the new zmr!!!!)

                        not to the engine, but the carb float could crack ( i have faced it in my bullet ), the slide could get stuck, float needle could remain in the main jet clogging the fuel flow etc etc.

                          kicker or no kicker in a fi bike the engine wont start because the fuel pump requires power to prime the fuel even before the bike is started

                            ^^ how do u explain that to the number of people who push start their bikes like 220dtsi, R15.

                              The reason a push start is sometimes possible with a weak battery is that the fuel system on the high pressure side is pressurised and will retain the high pressure for sometime after the fuel pump has stopped.

                              The ECU requires little current and even a weak battery can manage enough to power it. Ditto for the injector too. Once the engine starts then the magneto supplies enough power to run the fuel pump.
