    Clicking starter motor is normally a battery issue. Your battery has reached a level of charge that is not sufficient to turn the starter motor. Batteries will drain when you keep cranking them while trying to start an engine.

    I have charged the 2 batteries fully overnight before trying this avo and it is doing that so i doubt it is the charge but i will try a battery with a bigger cranking power tomorrow. Failing that can i open the gearbox cover or somewhere i can turn the engine using a rachet spanner?
    EDIT-
    I just found this so i will try it....
    The easiest way is to put it in gear, lift the rear wheel and turn the wheel by hand, “bumping it”. Otherwise you have to take off an engine cover that reveals the end of the crankshaft and then use a socket or wrench to directly turn the crank

    bring it over or i can drop in. galston. hills district.

    turn it over by hand first. they arent that hard. if it doesnt want to turn at all... you got issues. if it does turn, you can tell if its got compression or bad valves. should be able to feel both cylinders go through top dead center. and hear some hissing as at low speed some leakage is normal. rings dont seal perfectly.

    pop plugs. water or rust? shes stuffed. water (soap) in the oil is another sign you have an anchor. im assuming its been under cover so thats probably not an issue.

    fuel sprays out? its hydrolocked. needle valves or fuel tap. no big deal but you do NOT want to use power to spin up a hydrolocked engine, and the leaking bits need fixing. otherwise youll bend a rod or twist the crank one day. not good.

    if its turning over with no major issues, THEN bypass the starter solenoid. negative on frame, and tap positive on the lug on the starter. can do it backwards as well, positive to the frame. the starter will spin and the one way clutch means the engine wont. its an easy way to test the starter without digging too deep. can also hook the battery up, unplug the solenoid and give that some power straight from the battery. at that point you know if its the starter, solenoid, or starter switch... or battery.

    once you know its free to turn over, no issues popped up... with ignition on, it should have spark, with or without the battery hooked up. and with the carbs popped off, a drop of fuel down the intakes, she should fire straight up. rev briefly, die. at that point you know the engines good and its worth proceeding with.

    if it doesnt... can be as simple as mud wasps up the exhaust. pop the exhausts and try the fuel down the intake again. otherwise, valves are leaking/damaged.

    no spark can range from bad sidestand switch to clutch switch to neutral indicator to ignition woes....

    more than likely its just been parked and at worst, it will have rotten fuel in the carbs. no big deal. if it was me it would already be doing laps and risking licenses with unregistered vehicles, lol... or be cursing the guy that sold it to me?

Thanks so much for your offering to link up.

    Hi everyone, its been a bit of time since the last post. My hypothesis regarding the stuck gear in the previous post turned out to be untrue. There was no stuck in gear problem. I managed to get a few things done in the meantime. Repairs to various plastic parts, guages, electricals and buying things in prep to do other bit such as re-covering the seats. Check out the guage needles before it was a red WD spray tube cut to length LOL (near enough was good enough)... the journey continues...

    can someone tell me how i can run the bike using a jerry can for now while i can access the carbys to squirt some fuel into the carbys to get the motor running? do i have to trick the vacuum tube to get fuel to be sucked into the carby? i am trying to ensure the motor can run before sticking the proper tank on with the petcock that i am not sure is working perfectly or not. Just another step of making sure each stage is working... thanks in advance...

    Block the vacuum tube with a suitable sized bolt for running when the tank is removed. The vacuum tube will go to the petcock. It is used to open a diaphragm in the petcock. If you can find a suitable petcock which is manual (on, off, reserve) with no vacuum connection then use that.

    With the tank and fuel tap removed, the vacuum line will connect to inlet manifold or vacuum port on the carb. In any case you just block it off while using an external fuel source.

    Thanks Linkin and Andych, i kinda had wishful thinking to try and start the bike and see it would stay running but it doesn't. Fuel was not getting drawn in sufficiently. The carby clean was invitable.
    Today i got it out and found that it indeed need a super clean. I will run let the ultrasonic cleaner do its thing may be this weekend. I did find a broken part in one of the carby. It is proving to be a pain in the butt to remove. Might have to drill and use the extractor to get it out...
    Would anyone out there have 1 unused jet i can have or borrow?
    I already bought a carby repair kit... waiting for delivery in the weeks to come

    That's a broken pilot jet. You will need to extract it, thankfully it is a removable part anyway so not a massive problem. It would be a good idea to apply heat and penetrating oil before attempting removal. I would be using some adjustable multi grips or vice grips for that (small ones).

    At this point you will probably want to replace all the jets, float needle/seats and gaskets/o-rings. Along with the mixture screw assemblies.

    If you want to know if it will even run at this point, you can remove the carbs entirely and use some starting fluid, carb cleaner or petrol down the throats of the engine and crank it over. If the ignition system is in good order the bike will fire and you will hear it.

    Jets (and other bits ) are brass and turn to 'mush' pretty easily so take care when removing them

    Thanks Linkin
    I did manage to get to crank and start by spraying some fuel into the carbies so it is a good sign the engine is working.
    The jets and
    I bought the carby repair kit yesterday (hope it is the right one) and will have to wait for the delivery now.
    I will try the heat and WD40 this weekend sometime.
    Edit:
    I just had a chance to try again and got the culprit low jet out. Felt so relieved that i did not damage anything in the process. Initially I tried using a dremel cutting wheel to cut a slit and use a flathead screw driver but that just made it worst as the brass is sooooo brittle. I ended up using an extraction bit to reverse the jet out... Phew!
