cuthound Posted April 4, 2019 Report Share Posted April 4, 2019 Air in the fuel lines? If so check for the fuel system for air leaks and bleed the injectors. Link to comment Share on other sites More sharing options...
MtB Posted April 4, 2019 Report Share Posted April 4, 2019 Yes classic symptoms of air getting into the fuel system through a badly-made joint. Get the bloke back who did the top end rebuild! And welcome to the forum, by the way Link to comment Share on other sites More sharing options...

It is also a good example of one of those stupid BSS rules that can safely be ignored in my opinion. (As opposed to most of them which are sensible and good.) 2 Link to comment Share on other sites More sharing options...

So either examiners are making rules up again, or the rules have changed recently. Link to comment Share on other sites More sharing options...

Perhaps its another debacle like the all metal spill rails we had to fit, now they allow bits of rubber hose. Link to comment Share on other sites More sharing options...
john.k Posted May 8, 2019 Report Share Posted May 8, 2019 Changing a glass sedimenter bowl is a very sensible move.........Ive seen the things break just from being tightened to stop a leak,and broke one myself with just a touch of a spanner.............The catch is the ally bowl is very expensive.............good reason to change to spin ons.
