300/440/550 JS550-B1 fuel problem

[ville13bturbo]

My gastank will not give the requierd amount of gas, I can only rev half way.
You can se that the gas in the fuelfilter gets sucked upp quicker then it gets filled upp, I have unplugged the fuelvalve and just ran it from the gastank. What can it be?

Check the return line for a restrictor.

Post a picture of your carb/fuellines/fuel tank so we can see how you have it routed. How long ago was the last carb rebuild? Did it sit for a long time? Did this all of a sudden happen while you were riding it?

I bought it two weeks ago and it ran good in the water, then under the second ride it started to bogg down.
