Hi Richardthemotorcycle1 With regards to loosing your mind I can only prescribe olanzapine 5mg I am mental health practitioner
with regards to your carbs
I have the same issue with the reverse cones I have replaced my float valves and seats and "o" Rings. I also weakened the main jet needles to position 2 and 1 but this did not help
i am now waiting on main jets stepping down from 132.5 in increments of 2. Make sure......
If you have brass floats to set them at 26.5mm hight from the base where the gasket sits in
do not go above 27mm hight. once you have done this fit the bowls back on dont forget the gasgets,
use clear tubes to check the levels by fitting tubes to drain holes on the bottom of your carb bowls undo the drian screw but making sure your tubes are secured up the side of the carb body with a elastic band this will give you a clear visual on the float and fuel level ,,, if the carbs are off the bike as i assume they are you will have to feed fuel into the carbs using a large serynge or funnel necked down to fit the fuel line going into the carbs make sure they are level I used a small spirit level ,,, No Smoking
see my poats "what do you think" pics available
