[Can somebody help please]

Check the fuel shut-off valve to make sure it's all the way open, fresh gas?, kinks in the fuel line? battery voltage and voltage on the supply lines?

Thank you for the post I’ve checked all that and they seem to be fine.

I have a 2008 Royal star venture. I was working on it again today and it seems like it doesn’t matter what Gear it is in when I get a past half throttle it starts to bog out. I have rebuilt carburetor put new spark plugs and a new fuel filter and fuel pump I have drained all the old gas out and put new gas in. If anybody has any ideas of what is causing the problem please let me know thanks
