Hi guys,
Have a problem with my 1985 K100 8v.
When you rack the throttle hard, the engine will bog or stutter - and even more so under load. Yet if you gradually open her up, she pulls very strongly.
Shes had new plugs, leads, fuel pump, filter, hoses, regulator, air filter, and i've had the injectors cleaned and tested.
The fuel pressure is spot on according to my gauge.
Any ideas? I rebuilt this bike from boxes of bits, so know the bike quite well - but cant guess why this is likely to be happening.
