New fuel filters both bikes. Same model filter as last season, that worked perfectly.
Black was tested with straight hose without filter. - no change.
I've test fuel flow from the petcock and both bowl drains all are strong.
This issue really has me stumped. And even crazier both bikes are doing the same thing.
I shimmed the needles because I read it helps out for mid level power.
Blue had .60mm of shim last year and it was noticeable riding black that was not shimmed.
Idk maybe I don't need any shims because everything this so clean and fixed up?
I did try taking the shims as part of my troubleshooting and it felt like it ran better with them. I did not test ride or change mixture setting with them out but couldn't rev past the wall so I put them back in.
