Re: Z thou a2 brake prob

David Silvers, get one for a Cb750 f2,its exactly the same generic copy and usually cheaper.same ones are readily available on ebay as well,though round not squarish,or get the original bored out to 5/8.

Re: Idiot brake light

Most of the old z series 440 etc had these outage relays and they do crop up,should flash when stop lamp blows,come on when front or rear brake applied.be aware will not work if using led idiot lamps will only function with filament types,

Re: Cleaning Main & Pilot jets (Z1 )

Hold them up to a strong light,t should look like a spiders web shape inside the pilots due to side holes,main jets should be a clear hole,dont be tempted to use any hard object to poke clear as are easily damaged,ultrasonic cleaning is best.

Re: Airbox to carb inlet rubber

It is possible,easier to do centre ones first as long as new and pliable,get them over carb inlet first then use long blunt small tyre levers to get into airbox,note centre ones are diff to the outers.

Re: Carb jets and needles

David,if they are originals,may be some wear to the needle jets,not the main jets that screw into emulsification tubes,does it make any difference if you lower the needle?what notch is needle on?.flat spot you describe sounds like transition stage from pilot to main system.
