Honda-SOHC

Hi ,Ive finaly got to the stage where im getting the CB5OO ready its MOT (photo attached) however im having probs with the carbs i have replaced most parts with a KEYSTER carb set from the USA which had  a 26 needle ,100 main jet,40 slow jet , air screw and spring ,float needle and holder,and and new gaskets also in the kit are some steel ferrels and washers which im not sure where they go.any way i rebuilt the carbs with the new parts set the floats to 22mm and pre sync the carbs with the drill bit method .ive yet to balance the carbs .im having trouble with the carbs over flowing not always the same ones ive stripped and checked them 6 times at least only once have they not leaked i the checked the amount of petrol in each one and had approx 55ml in each float bowel,next question the keyster slow jets are not the same as the ones in the carb(photo attached)so i kept the old ones in.Next query the air screws are mounted on the side of the carb set at one turn out so is it screw in or out to enrich the mixture.Finaly clutch ,when i select any gear from cold it goes in sweet yet when the engine warms up the gears wont go in it feels as if the clutch is not fully disengaging (clutch drag ?).so any help would be much apprciated.thanks mick and happy easter all

HI ALL .AS MY POST SAYS IM LOOKING TO CHECK THE DATE OF MANUFACTURE OF MY CB500/4 .THE LOG HAS IT BEING REGISTERED ON THE 3/7/1973 IM SURE IVE SEEN IN ONE OF THE POSTS THAT ONE OF YOU GUYS CAN CHECK THE YEAR OF MAUFACTURE IF I CAN SUPPLY THE FRAME AND ENGINE NUMBERS AND YOU CAN CHECK IF IT WAS MADE BEFORE JANUARY 1973 AND SUPPLY THAT IN SOME OF PROOF.OF COURSE THAT MEANS I COULD POSSIBLE GET FREE ROAD TAX? OR AT LEAST THE OLD BLACK AND WHITE NUMBER PLATE WHICH WOULD COOL ON THE BIKE.IM GOING TO BE OFF WORK FOR 3 WEEKS LEAVE AND IM HOPING TO GET THE CB ON THE ROAD BY THE END  OF IT. THANKS IN ADVANCE MICK

Hi all im mick from wrexham n/wales ,ive just bought a cb500 k1/k2 for a project over the winter months.MY first honda was cx 500 back in 1988 (cam chain gremlins),then CB750f good bike but flighty front end and which i dumped on the road by kates cottage IOM tt 1982 followed by cx500 eurosport.i then was off bikes until 2006 when i got a suzuki bandit 600 which i got rid of this year.since then i have rebuilt a suzuki ts 125 and sold ,tha GB250 which i converted from a rust bucket to a tidy classic .first time ive made money on a bike  .ive been a biker for over 30 years (and got the scars and aches to prove it).So thats me i look forward to meeting you in the forums and picking your brains for help with the CB500
