It's done !
My bike is now pumpless.
I checked float level and it's between 2-3mm per manual says.
On startup in the morning it happened many times that bike start well with enricher, but after warmup when I turn throttle just a little bit or more engine stutter and stall. I have to pull enricher full start it up, push it halfway and start to ride before to push it back. I can ride 100-200 km without any problems until I stop it and try to restart it 20-60 minutes after a coffee/beer stop. It doesn't happen all the time, but most.
For now I don't have any filter on my fuel line and I'm straight from petcock to carb
passing under intake manifold.
I also feel like engine now run leaner, I checked spark plug and they're more grey than brown. Still have the 165 stock main
jet with regular air filter and V&H
longshot. And I did not changed any thing but needle valve and o-ring gasket.
