Hi again guys!
Soooo after solving this freaking problem...
http://foc-u.co.uk/index.php/topic,23230.msg267705.html#msg267705i am facing another fuel problem that was coexisting with the previous one.
As i am standing at a traffic light or a crossroad or something like that,with the engine fully warmed, and i lightly blip the throttle the rpms drops significantly and come again at proper idle speed or when i try to start moving the bike feels too rich and want more throttle opening.
The pilot screws are adjusted at approximately 2.5 turns (01 model), if i try to reduce this,the bike doesnt idle properly.
I have tried to set the float heights in many different settings.
To archive the 3.5 mm above mating surface like Yamaha suggest, i have to set the float height at approximately 15+ mm above carb surface when bench setting them,but the bike with that setting, fills very strange and wont idle properly again.
Now i am at ~13.5 mm and with the tube test it reads something like ~6.5mm
above mating surface.I m confused again for focs sake! Air filter is clean,carbs are very clean, i have this problem with both carbs sets i have( spare parts!!!!), pilot jets are yamaha's 12.5.
Any help or idea will be much appreciated, because i am out again...
