hi i have a 1999 busa problem started a week ago when she started running roughf ..
so after striping fuel pump and cleaning filter wich was realy dirty i have a new one orderd now after re asembly the bike will not start it is getting a bit of fule trought the injectors any thoughts guys
 
Is the new fuel pump installed or on order??

If your filter was dirty, more that likely the injectors are dirty as well. When was the last time the injectors were cleaned and calibrated?

Before you spend any money on cleaning or buying a new set of injectors I would see if you could borrow a set from a friend to test.

Also I would check all electric to the pump and make sure it is priming the injectors, you can here it run without starting the bike. Key on, kick stand up, and hit the on switch (not the starter button) and listen for the pump running.
 
have tryed that it seems to b priming all the injectors seem to b putting out fuel for one squert then not much ??
 
thanks for that both of them filters are cleaned .
problem must b injectors :banghead::banghead::banghead: is their any way i can clean them my self ??

not very well. You can try spraying carb cleaner in the injector but the injector screens get clogged pretty easily
 
ok budy will try that tommrow it almost 1 am hear in ireland so it b bed time for me thanks for all your info will try that tommrow and let ya know
 
if your fuel system was that dirty, you may need to have the injectors cleaned
 
You might be able to check the fuel pressure on the rail and see if it's in spec.
 
wahoo she sorted thanks guys for all your help and info after cleaning injectors with brake cleaner .
but i happen to notice an o ring out of pump when i was cleaning up and seen it today and after looking thrue manual i figured out whear it was for number 27 on that link lol the small thing that make such a big thing run ,,

Glad to hear she's running again! Something to think about, if cleaning those injectors with carb cleaner helped its almost a definate that they need cleaned and calibrated. Doing this will be the difference between a running bike and great running smooth bike.

Good luck

1999 and 2000 Busas are prone to this because of the fuel pump design. What you see as rust in the filters is actually part of the fuel pump impeller that rubs inside the fuel pump housing. As long as you use a 99 or 2000 Fuel pump you will continue that have the clogging problem over a period of time. I would suggest going to an aftermarket fuel pump and fuel pressure regulator. Once this is done you can install 2 fuel filters (one before the pump and one after the pump) this is eliminate the problem. Then pull the screens from the injectors.
RC Engineering does a great job of cleaning and balancing injectors.

RC Fuel Injection

MPS Racing can clean them but not balance them

cost is about $100 to clean them
