    If you've still got the manual, see what the coil nominal resistances are supposed to be - and if the Dyna's match that.
    I've got a niggling memory that the OE coils are unusually low ohnms.

    Hmm, I could ask for the std coils off the impulse.

    I might have to send you Kali's carbs.

    Actually they are next for my final fling of getting the sodding thing starting properly.

    Well I pulled the 2nd set of carbs to see how the chokes were fed.

    Hmm, so the brass tubes sit in drilling and have 2 drilling, centre and side.

    Pull carbs off bike. Sure enough brass tubes are blocked on both sides of twin carbs. Finally have a use for my jet drills. Tiny holes.
    Then check the float bowls. Of the 4 I have 3 are blocked. More careful drilling. Finally petrol when tipped into the bowl fills the drilling.

    Back together problem sorted. Will it start? The fuck it will . Arseholes!

    You've had it running though yeah? Cunts of things when they dont go for fuck all reason. Had a GF250 that wouldn't go because of broken magnets in the hall effect generators once.

    Yeah when it's warm it's fine.

    Tried brake clean which is my usual starter fluid. Might have to buy some better stuff.

    I'm guessing you've tried winding the pilot screws right out.

    Yeah. Need to be a bit to reduce off idle stumble. The choke was having no effect before. Have to start it to see if it is doing something now. Well actually it was leaning it before so was better off with it closed.
    Not surprising as the fuel feed to it was blocked . That little guy feeds the bore the choke tube slides into. Part way down that bore is a .7mm drilling. Not sure why it is so small. If it's smaller than that the fuel bowl can be filled and it won't fill up the bore.
    Does now.
    Thought I'd found the issue and why it has always been a pig to start.
    I can't give it back to her this bad though.

    Ha. Just reading s Practical Sportbike mag i subscribe to. Letter in about hard starting GSXR400. They offer up the choke drilling, the valve clearance, the coils and CDI. Done all those. Well the last two I'm assuming as I can get a spark to jump 8mm from a HT so that seems pretty useful at cranking speed. Dyna coils with std copper leads. Could swap a spare CDI out of desperation but not sure how that could help.

    I'll get some ether start fluid and then check if the choke is now having and effect.

    Well got back from ride early and after some van plugs (tedious but gap was like 3mm)
    Dragged the GSXR out. Quick spray of Startyabastatd and fires straight up no choke. Then the button stopped working. It's been dicky.

    Pull twist grip off. Lots of bodge joins. Solder joints in heatshrink but all that does is make a great joint that is stiff and will fracture. Replaced a full wire and ignored other horrors. Although I did remove the nasty splice fitting.

    Squirt. Varroom.
    Apply a bit of choke and hey what do you know? The choke is working as it should.

    Will try it all again sans spray later.
