Engine Cuts One Pot When Reved

[fixitsan]

It's baffling why it would rev only on partial throttle, but then again, on partial throttle you maintain a high intake vacuum, where as with a wide open throttle the vacuum drops away rapidly, so there's at least one major difference.

So you could still be right about the carbs.

When you pin the throttle open  you expect maximum flow in the carbs, and if there's any debris in there it will likely get sucked into the jet then, more so than with a partial throttle, when fuel flow is much less ?

 

Maybe ?

 

My 850 carbs were also 'fun'. I had similar problems like other riders have here, you clean the carbs, the pump, the filter, and seemingly from nowhere a bit of something alien blocks open the float bowl needle !
