929 fuel pressure regulator
So on closer inspection of my fuel system, it seems the FPR is faulty. It seems a previous owner worked this out too and simply added another fuel line to the vacuum side of the FPR and turned it into a pass through for fuel haha. And the vacuum line has just been blocked off.
This probably explains why the bike likes higher revs but it seems mostly fine.
Are there any problems leaving it as is or should I spend the money on a new FPR? It's mainly a track bike so rich idle is not really a worry. Thanks.
