Any help is appreciated I got this bike as a project bike so I can learn to work on them. I just rebuilt the carbs, added velocity stacks, and open pipes. In the process of trying to tune everything in and for whatever reason when I hit 70 mph the engine stumbles and pops a few times. In first, second, and third gear it can handle WOT but as soon as I hit 70 it just bogs down and I have to coast to let the bike catch up. Im thinking I might have to up the main jet size but I honestly have no clue.
sounds like you are running out of gas. Classic fuel delivery issue. Fuel not entering the float bowls fast enough. What bike are you working on? did you eliminate the fuel pump?

The bike is pretty much stock except for added running lights and the performance kit. I noticed before I did the performance kit it would start losing power on the top end of fourth gear which is what prompted me to start with the kit. When I rebuilt the carbs I added the new float needle but didnt adjust the float itself should i start there?
