    MAX Power Delivery

    hey guys
    i have a doubt in my mind

    for example
    lets take a bike HONDA DIO producing 7bhp @7000 rpm
    does this mean the bike can go only till 7000 rpm ?
    .
    and by going for big bore setup , free flow exhausts free flow air filters
    and other sort of performance mods

    the BHP increases
    lets say upto 9-10bhp
    and if it can go only till 7000 rpm can the bike deliver the increased performance that is the 9-10 bhp ?

      9-10 bhp is something that is attainable, but it would need vigorous mods... and it the end it would turn out to be unreliable on a stock engine, unless it is is designed to take mods. On a stock engine you can expect

      For a proper power expected mod you will have to take care of the gearbox too.. well i dont really know anything about the gearbox, but i believe we can attain some good increase if we consider the transmission too..
      Presence of MIND and self CONFIDENCE is the primary aspect You need to be on road, not what brand your riding gears are.
      If you lack these two then DONT

          Hi hunkofgals,the answer for BOLD part:
          Usually, the Bike specifications tell the MAX power (what bhp at what rpm). In your case, Dio makes a Max of 7bhp at 7000 rpm. The bike will for sure go higher than that but the power delivered will be lesser than the 7bhp!

            please explain/ elaborate bold part and is it applicable on any engine..?
            Its not enough to know how to twist the throttle; you must have judgement to know when and where to do it.

              no not for all engines..but for most bikes we have! and remember the Max power is at a specific RPM where the Bike is tuned to give the Maximum power..

              See this link for easy explanation of power/torque/power-torque curves/high-revving engine vs low revving engine,etc.,

                @hunkofgals:

                Every engine has a transmission system, the only difference is in the method the gears are shifted, manual or automatic. In automatic mode the transmission or change of gears are taken care of automatically, while we riders shift in manual mode.

                There might be some people who do mods or have new gearbox designs for specific models..
                But in a scooter of this cc, there is none.
                You cannot expect any great power gains from your dio.
                You can go for a free flow air filter and upjet your carburetor. and that will bring you 0.5-1 bhp increase..
                Presence of MIND and self CONFIDENCE is the primary aspect You need to be on road, not what brand your riding gears are.

                  i have got big bore setup done
                  recently added performance air intake
                  and free flow exhasut
                  ngk plugs
                  spit fire cables
                  upjetted the engine

                  what hp increase can i expect
                  stock was 7bhp

                  and all the above mods are done perfectly
                  and

                  do i need to change the CDI too
                  ?
                  as i heard somewhere that racing cdi allows to go beyond the stock rpm redline mark ?
                  is it true ?

                    I dont know about the racing cdi's but check with your tuner if he can modify the clutch i.e make it shorter
                    many a times all these mods generate quite a bit of power but the clutch does not let you use it.
                    What size bore are you running??

                          Well you can expect a maximum of 8.5bhp.

                            hi, why do u worry much about bhp figure? If the performance is good & satisfactory, be happy with the work done 1mm cc increase would not do any difference. If you want more power you can do head porting, stiffer valve springs, bigger piston like 57mm will surely give you good power
