    So has it been sitting since January without running now ?
    Was there fuel in the bowl's when parked ?


    I have an idea for you to try
    Take the airbox off the carby's, put the palm of your hand over carby 1 to seal it and crank the bike over for a few second's
    Take you hand off the carby and put it over carby 2 and crank it for a few second's
    Same with carby 3, then carby 4
    You should get a bit of fuel on your hand's each time it crank's over

    Now try starting the bike normally, when it fire's and start's it'll be a bit rich due to the extra fuel but it should clear up pretty quick

    Doing this ^ i have cleared carby's that have sat for quite some time before, it draw's fuel through the pilot circuit and seem's to clear any blockage's

    It was running for 10-15 minutes on Tuesday ... but needed starter fluid to get it going initially.... yea fuel is old .... but it revved freely and started once warmed up so to speak
    choke makes a difference when trying to start it when moved on and off ... whether its working as it should , who knows
    I tried like 4 different fuel pumps trying to get one that 'worked' ... maybe crud has blown thru into the carbs from one of the old ones that were just sitting in a box

    pain in the arse .... 7 years Ive been 'fixing' this pile of crap

    Any more major bike builds wont happen till my workshop is built ... doing the ZXR reminded me of how crap it is here now working 'outside' etc

    Things like the carbs and wheels will probably end up on the flyer and its now out of rego anyway ... its had its day
    The engine needs a total rebuild and third gear is stuffed also but for the time being running down the track will do while its still in 1 piece

    Need to find a way to spray engine start into it without having to take all the bits off. If I remember right, it was hard to start, but ran fine once hot. Started fine when cold with a bump start (from memory)...right?

    Thats about it ...... I started it today with Aerostart but it took alot ..... didnt try to bump it as I wasnt going to try pushing it up the hill..... bumping worked easily that first time at Gunnedah when cold and then started via the starter all weekend.
    When racing is looming again Ill try that here in the street (when theres 2 of us) to see if its a common occurence

    Plan is to change a few things then just drag it till the gearbox and/or engine self destructs

    Might I suggest that your pilot jets are blocked? :lolsign:

    When do you plan to make a tank skin to go over that? Maybe some kind of hinged unit for easy open and close to get to carbs?

    Should save about 4-5KG ditching the metal tank.

    Pulled some more extraneous bits today

    Chinese fuel pump had died ..... might not have helped trying to run the bike the other day ... put the original back in

    Ditched the coils as I have these sticks on the way

    coils.png COPS.png

    Ok electrical honkys .... would Jaycar have these maybe? .... or just the bare terminals to rewire them?

    coil plugs.png

    I had a good look at the diaphragm vents also .... I dont know about there being 'filter' material in there but they sure were clogged up with junk ... might not help in the act of carburetion either

    filters 1.png

    before

    filters 2.png

    after the air gun


    filters 3.png


    Also time for some gearing experiments for the ⅛ mile

    Its had stock gearing for years so a 17 front but lets lose some teeth and get the most out of that 18500rpm :D

    13 or 15 ? hmmm :cool:

    Go with 15 to start with... 13 might cause you to see the sky at take-off... and Wheelies are slow.

    What is your average speed over the finish line atm ?
    And in what gear ?

    I would gear it down so you are crossing the finish line around 14,000 rpm's ( a touch below peak horsepower)
