Gutless at 70 mph

No guts…
Just had carbs stripped rebuilt new diaphragm in each carb but when it gets to 70 it just starts cutting out. Anybody have advice on this issue?

  1. Is that all you’ve touched on the bike ?

  2. Did you do those diaphragms because you had a problem in the first place ?

At least one was holed… so given their age The carb guy changed them all… the rear right kept flooding…so all four were ssrviced. Only the carbs. The reg rec was swapped because the other was goosed tested for current etc and running spot on power wise from battery when engine was running.

Best to start with checking the fuel supply is up to scratch.The manual gives details of how to test the flow.
Rust in a pipe,a kinked fuel line or a choked fuel filter will show up doing this test.
If all is OK,I would have the carbs off and have them cleaned in an ultrasonic bath.
