So i start up my rb, it's been like 3weeks. good idle but starts to pop at idle. Took it for a ride and just felt like crap. Was thinking maf but this started awhile back. swapped mafs. same prob. Changed fuel filter a month ago and went away but came right back. So i'm thinking fuel filter is clogged again.

Suggestions for cleaning out fuel lines and filter

You can disconnect the fuel filter and cycle the ignition on. The fuel pump should pump for a few seconds. Put a glass jar on the end of the fuel line so you can see the quality of the fuel coming out of the line.

Check the filter on your fuel pump, could have fallen off or be clogged.
