    The bore can be bored upto 8 oversizes. Only the bore job and the piston should be right. Indian made pistons are available upto 4th over so you have one more life left.
    Regarding piston mods, it depends which piston he has used. Its usually a failure as it requires high precision machines and engineering. Hows your compression?

    +1;
    What happens here in local lathe is, these guys DO NOT have accurate measuring instruments upto microns. So what they do is, they simply take piston's size as reference & shave the cylinder. This is not good & suggested engineering way. The recommended gap between piston & cylinder walls are 20 microns from factory. Now imagine the shoddy job; these guys say that the clearance will be automatic due to wear & tear between piston & cylinder walls. My question will be, which one will get eroded? Piston or cylinder? Either cases, we're the losers!!!

    @sriram: yea even he said like that!! but wont that affect the life of that bore??

    You need to open up the cylinder head, scrape the carbon from piston head & check the size; 3rd oversize is 0.75 & you should see that being embossed on the head.

    Hmmm...these are little difficult to help over chat & forum!!!

    I don't know what to say; your rebore could be done on existing cylinder as well as they could insert a sleeve; like I said above, there're too many things involved. To address specific questions, I'd suggest opening a dedicated thread for you.

    PS - Avoid SMS language in the posts per the forum rules

    We're religiously following our law here - http://www.xbhp.com/talkies/xbhp-off...rself-gtg.html

    But again, from my experience, I'd say, buy tools & start things on your own; do not wait for any incident to happen, simply start removing the parts by yourself. Ensure you've a spare vehicle, incase you're unable to put things back. Not that I don't want to teach, but, there's nothing that can beat the confidence of one handling his own ride all by themselves. You can always reach out to me, I love talking on automobiles through the day

    Well, not only you, its for everyone that mechanics cheat. Trust me it happens in a different form even in western countries & I was surprised. Let me give the difference...

    India - The mech gives a high talk saying, "Saar, 5 speed, super, will smoke out RD etc"; when one falls into prey, they replace with all substandard parts or fake ones & steal the original parts.

    West - The mech states that the job will take X hours & he can do it for $Y & he'll do it for less than $Y. Ultimately, he'll not even take quarter of X hours & will charge you for it. That's one way.

    In second form of con, they do a misguide because of their competent knowledge to fix the problem (they'd replace the part instead of fixing) thus charging for what they do.

    I simply turned my anger/frustration positive & turned my anger constructive ; Result? I don't have to depend on mechs anymore; I don't have the fear of loosing any part being replaced with fake one

    Well, I would go beyond the install doco these days

    See @Yamdoot, like me, many ppl may not have sufficient knowledge, but they'll be willing & eager to help, so try to pour suggestions, which I do APPRECIATE with whole heart.

    So whatever ppl taught, helped me understand what I'm doing. Fortunately my education helps me to improve my knowledge from what I'm doing & what I understand

    Next time, someone struggles, I'll be able to guide them from WHEREVER they stand , now that's the confidence I've built.

    When I entered this community, came with little or zero about RX. Trust me! Just over a year, only learned how far is 'knowledge (on bikes)' from my understanding, woah! it is a long road. Thanks Aargee for your kind words.

    @ Aargee.. good you have ppl by your side. from what i know about Sri, he a grt person..
    Anyways, lets get to your prob solving.. I was wondering why ppl were telling you to fully rotate the stator counter clockwise when the install docs clearly say to start fully clockwise with the pulsar coil at 5 or 6 o'clock and then move CCW as you find the rite spot.
