Z1000J idling too fast after carb balance
Posted: Sun Jul 15, 2018 12:51 pm
Hi,
Checked valve clearances, set ignition timing and all now ok.
Idle has always been a bit lumpy, so decided to balance carbs (standard 1000J CV carbs).
All went well, throttle response and overall performance is now good, except....
it will not idle below ~1500rpm when hot.
Cold start is fine, but then idle just gets faster as it warms up until it settles around 15-1700rpm.
The idle speed knob will raise it further if screwed in, but it won't drop below 1500 when screwed out !
Nothing within the throttle/carb system appears to be snagged or not moving correctly.
If there's a clue anywhere, the idle speed did rise (and smooth out) as I balanced the carbs, but now seems to be stuck at this higher speed.
Should I just screw all of the adjusters right in and start again?
Any suggestions welcome.
Thanks
