Hiya all???:banghead:
am having problems with me 1999 busa! when cold it ticks over and runs sweet. go 1/2 mile down road and then it coughs, spits and sounds like a bag of nails. if you open her up tho she flies like its new, but cruising at 2500 3000 rpm she miss fires, you can get F1 light flashing. I've put new plugs in (original spec), had a full service on her and she still after a while starts to play up. am toying with the idea of getting new coils but money don't grow on tree these days so before I do. Anyone put me on the right track?? Phil
 
hi thanks for asking.
there is no code coming up. but the f1 light is on and "f1" is on screen. after switching it off , it resets it self. havent been out on it since as i dont want to do more damage to it.:thumbsup:
