Rejet after cam change
Posted: Thu Oct 05, 2017 3:58 pm
Hey, hopefully someone can shed some light on this. I've totally restored my zxr l3 but unfortunately I'm having some running issues.
She absolutely perfect on the bench. Starts on the button, revs to the redline no problems.
As soon as she's under load however she struggles to rev, lacks power and stalls at idle.
I've changed plugs, coils, wiring loom, battery, igniter. Compression test comes back at 120-150-150-150 (the 120 cylinder has scoring)
The carbs have been vapour blasted, rebuilt with all new kwak seals and a Dynojet Stage 1 kit installed. Balanced. K&N filter
I've had the head skimmed and have had the SP adj cams dialled in by an engine builder.
Ran out of things to do but do you need the SP igniter etc with cams or: is the bike firing early/late? Or is it more likely a jetting issue?
Any help would be appreciated
