    thanks for that, i will give it a go and see if she turns. the plugs seem to have small numbers on them, the two far plugs have the number 3 and 4 labels attached to the tip where it continues on as a wire. the other two, well they have 1 and 2 written on the actual plug.

    i attempted to jump start it off the cage yesterday but still does not seem to want to turn over, granted all plugs were connected. again the lights dim, to almost off when i press the starter button.

    when i turn the key to on, exup starts, lights and instrument lights come on.

    not sure if it is related but i just remembered that i had to replace indicator globe twice in the last two weeks. one left hand front and the other left hand back (from memory).

    You definitely should take the plugs out and try and see if the engine turns over by putting in say 3rd or 4th gear and pushing the bike or by taking the magneto cover off (right hand side) and turn the flywheel by hand (clockwise) - it should turn easily....If it does then it is most likely an electrical problem.

    hey guys,

    i took off the plugs and tried to start it via the starter button but no luck, just the same response as before, but, did not try to push start it.

    so, will give this a go today and also will try by taking the magneto cover.

    will let you know.


    thanks for all your help guys

    The next 2 things to investigate would be the starter switch and housing and starter solenoid.

    so, tried to push start it without luck. gives the same result. it also locks the rear wheel. i also took off the magneto cover but the wheel will not turn.

    my uncle, auto electrician, comes back to perth tomorrow so i might get him to take a look. im guessing, if its electrical the principles would be the same, car or bike.

    will let you guys know..


    thanks

    Sounds like a mechanical problem if you cant turn the engine over at the flywheel with the bike in neutral. Try turning in both directions and let us know how you get on.

    My advise....let me take it off your hands for a few dollars before it really starts costing you money...$500 sounds fair given that its a non-runner.

    hi dave, i will give it another go.

    superGlide, thanks for the offer but i will have to decline at this time. In a way its not a bad thing that its happened. im learning alot more about the bike, which can only be a good thing. As i am not strapped for time im willing to try a few things here and there until i take it to the mechanics.

    also, as i am close to being able to go and get my open class (R) i am looking for an upgrade. I did see a few FZRs for sale, a 600 and a 1000 <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) --> but i am leaning more towards a cbr or a gsxr, see how we go i guess..

    SM0T0 - Just a wild shot here - Did you by any chance take out the cam chain tensioner during your maintenance session????

    ACE, i am not sure as to what you mean if the plugs are too long, they seemed to work previously, as to your second question, no the bike does not turn when plugs are off. it does not seem to make any difference if the plugs are on or off.

    dave, i wouldnt think so as i did not touch anything else while doing the service. What i did was, took off the exhaust including the headers, released the oil. while waiting for the oil to drain i replaced the spark plugs, changed the filter, filled the oil, put back the headers and exhaust.

    I am begining to wonder what could have happend. Another long shot - It is possible for a small rock to drop in the park plug holes when you renove the plugs and then sit inside the cylinder or jamb in the valves.

    It is a bit of a chore but if you take the camshafts out you should see all the valve tops sitting at the same height.

    i remember someone having a similar problem recently,after a service same thing it jammed afterwards.

    my advice was to put the bike in 6th gear and rock back and forth, it seemed to do the trick perhaps you should do the same it worked for them.

    flat battery.....

    i thought i had a flat battery, but it was a hydraulic lock. ended up burning out a starter motor. $$$$$

    did you put the oil in the sump or in the spark plug wells?

    this may sound a bit nuts. try put the bike in gear and rock it backwards while sitting on it. You should hear the starter motor turn over. I do this when my stater clutch wont engage or the starter wont spin.

    hey guys, thanks for that, i'll add it to my "to do" list.

    raptor, have not tried that, will give it a go at first chance.

    SOBIL, oil went into the sump. if it is the starter, how much can i expect to fork out?

    need to work out my spending for the next few weeks <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->



    thanks guys

    if you can't push start it, don't worry about replacing the starter motor - obviously that isn't the problem.

    Considering what little you did, it does seem strange that it's just died.

    will be interesting to hear if you can turn the engine over backwards (ie as said above, put it into a relatively high gear and push the bike backwards).

    boys, an update..

    finally she turns <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) --> putting her into high gear and rocking backwards seems to have unjammed it. so she now turns but wont fire. i think its because she has been sitting there for a while now.

    so, im gonna go have a try at roll starting her..

    will keep you updated.


    thanks all for your valuable input, very much appreciated !!
