  • P 135 starting issues

    Need your help guys. I just just did the first service for my bike. Am facing a problem now. It starts after some five or six kicks, and the idle rpm is quite low. Feels like when will the engine shut down. And when I raise the throttle, it sometimes shuts down. Once it gets moving, there are no problems though. Starting is a big issue. It goes to 1k rpm, struggles and gets switched off.

    Once I get it moving it doesn't act funny though.

    Any inputs?

      Increase you idle rpm to 1300-1500,
      and if it does not solve the problem get your carb tuning right because SVC guys most of the time try their hands at carb tuning and mess it!

        How do you set the idle rpm? Can you elaborate? I am sort of a newbie. I do know that it has to be done when the engine is warm. That's about it

          Idle screw is closely linked with the throttle cable.
          warmup your engine and set the rpm to about 1400(as said by bajaj)
          and your bike will be fine!

            The manual suggested idle RPM is 1400 (+/- 100) AFAIK. You can easily bring it up if it is below that range.

            To adjust the idle, first you have to find the idle screw. I have not seen a P135, but i'll tell you how you may find it. When the engine is off, rotate your throttle up and down, (accelerate/decelerate) while looking at the engine closely. You may want someone to help you. You will observe a part moving along with the throttle. This is the throttle lever, and is connected to the throttle via a cable. There should be a screw touching this. It can be adjusted by hand, to keep the throttle more open, when there is no throttle applied by you.

            Do this adjustment only after you have warmed the engine (ride ~5km). While the engine is on, make very samall turns, carefully observing your new RPM. Do not touch the throttle when making the adjustments. Wait for the RPM to settle before adjusting again. When you are done, rotate the throttle once or twice to make sure that the idling speed does not change. If it changes, re-adjust.

            DO NOT adjust for idle RPM higher than the recomended range.

            Bajaj's own words: "Do not attempt to compensate for faults in other systems by adjusting the idle speed."

            During the run-in period and preferably always, you should start your bike and wait for 60-70 seconds before moving off. This will make the oil warm and reach all parts of your engine and evenly warm it up. Otherwise certain parts of your engine are warm, certain parts are cold. This leads to a lot of stress on the engine.

            If you wait that one extra minute you can save a lot. You won't have shutdowns, your engine life is extended, etc...

            NB: If you adjusted for 1400 when it was properly warmed, you WILL NOT get 1400 when it is cold. When you start it, it will be less than 1400, it will very slowly rise to 1400 as your engine warms up.
            If you adjusted for 1400 when it was NOT properly warmed, you will get MORE THAN 1400 when it is warm. When you start it, it will be 1400, but it will very slowly rise to more than 1400 as your engine warms up.

            Higher idle RPM = higher fuel consumption, higher engine temp, higher wear on clutch, higher engine wear.

            What i suggest is you find your best setting from the lower side, not from the higher side. ie: set it to as low as you can in which the engine wont' shut off when warm.

            If you still have problems, i guess you can look for other causes.

              Its still under warranty i guess don't try any experiments at this stage
              just go and insist the service center guy to look in to this issue
