carb fiddling


all needles raised now by 2.5 mm using a brass spacer. ive left the pilot jet at 2.5 turns out. Airbox is off totally and all inlet rubber clips tightened. The engine revs freely with no lag when the throttle is blipped to around 7000. Seems clean enough. Still got to test it under load.

If I can run it now without restricting the airflow into the funnel then I may be able to use the Suzuki Tlr tank as Ive always preferred the shape. May be create a way of directing the air from the fairing scoops of the tlr fairing.
I ve also re routed the clutch pipework so it doesnt foul anything as before it was the wrong side of the forks.
To use the Tlr tank Ive got to seal the underside of the tank where the Tlr's fuel pump would have gone. picture to follow.
Front brakes need bleeding as they get spongy after its been left standing. Clutch fluid needs topping up and bleeding. Little by little its getting there.


Looks quite the beasty now.

testing!.....

just a brief test, needs a lot of fettling. I have 2 sets of carbs, 1 standard jetting.........this is my back up. Current set up a little wild. special adapted needle nozzles from cbr640f-h Leon Moss stage 3, matching neeldles, first set to 1.5 mm raised needle position( needles use spacers to raise or lower).Huge 150 main jets....may be too big.
airbox on with filter.........tried without filter engine would'nt rev passed 4000 while static......hmmmmmm.....would rev with restriction over the trumpets so put the entire filter on , sealed box again just witht he snorkle area removed....revved fine.
load test....would take off well but huge flat spot 3500-5000. turned pilots out 1 turn...not much....then think between 3000-8000k is where the needle jet works.....so raise the needles to 2.5mm from base of needle.
But all this messing about is fruitless because after all this I realised I hadn't tightened up any of the inlet rubber clamps.......!!
start again.....get proper track arranged....going to be difficult as now back at work.
