    And I'm abit naive when it comes to re-boring...
    Can you please explain what it is, and how its going to be beneficial???

    Not really an expert , but here's my 50 ps worth..

    Over sizing and re-boring is normally done when you have some damage on the piston/cylinder and you can't get the full potential from the bike . It normally happens if a piston seizes and the piston / cylinder gets scratches on them . In that case tiny volumes of air/fuel mixture escapes through the gap and you don't get full compression and lose both power and FE . When we put in an over size piston ( difference will be @ .25 - .50 mm ) the cylinder is bored to accommodate the bigger size piston and ( I GUESS ) BIGGER RINGS ARE PUT IN .This in turn increases the volume of the cylinder and you have slightly higher power output . If you want you can negate the higher power and turn it into better FE .

        Sorry t disappoint you bro It's not a DIY job . You'd at least have to give the cylinder outside for re-boring . I guess the rest you can do . If you're after more power 17/223x230 would give you just .53 hp increase . That's the reason I'm not that interested in it .
        Using liquid gasket would give you another (don't remember the exact figure mentioned earlier in this thread - guess it was psr who said it ) .50 hp increase . With both these mods I guess you can crack the 140 kmph mark ( assuming you are now getting 130 kmph ) . Well , now that I am putting the two together ( haven't done so in the past ) it does seem alluring ...

          OK,So where can we get next size pistons? How much will they costs? Is there any particular brand for pistons?How much will re boring cost's?

            Neutral(indicator) Gone off + ZMA doesnt start without clutch in neutral!

            Hi! guys

            I am facing a problem.
            Couple of days back, the neutral indicator gone off and isnt glowing since then.
            Bike isnt starting on applying self starter(in neutral), unless clutch is applied.
            Checked the two wires(located on the left lever assembly), everthing is good.

            Searched in Xbhp threads, but didnt get any result.

            Dont know what is the problem. Can any one help me out?

              Removing the gasket from the bottom of bore will give you between 0.8 to 1 hp increase...and increase in FE, while overboring to size above 230cc can be done with Pulsar 220 std piston which can give you slightly less than 240cc,with improved FE.

                Two possibilities...The neutral stub in left(gear side) crankcase had developed loose contact to connector wire or to inside connection...or the neutral plate inside crankcase is no longer making contact with the connecting stub...While the first is an easy fix by replacement of neutral connecting stub the later of the neutral connecting plate will necessitate splitting of crankcase.
                Are you sure the clutch switch is working properly ?

                    Thank you for responding PSR sir!

                    After just looking it, I think Clutch Switch is properly!

                    If I am not wrong, clutch switch is the metallic plate locate near the kick or alternator, above the Oil filling hole, which reponds on applying clutch lever.

                        I believe he's talking about the wire like thingi we see on the gear side, when we remove the sprocket cover.

                              Hey fellow mates.

                              Need help on an electrical issue. Off lately I have noticed that the indicators on my bike take their own sweet time to glow & if the bike is OFF they refuse to blink.

                              I suspect the blinker going kaput, so can I put any other bikes blinker or I have to put in ZMA's only? The other thing I have noticed is that the indicator on my earlier rides were glowing instantaneously when pressed but on the ZMA its quite slow.

                                1.You'll need to check for the Flasher relay.
                                2. Other bikes indicators?
                                3. If the blinker bulbs are not from the same make or not bought together, chances of blinker timing differs when compared to left and right. This is common for any bike.

                                Experts, please add/delete if any.
