Message My Burg NA Zed is a California Daily Driver.. My Outside Temps range from 8F up to 115F..
This Zed has a Hot Knock above about 110F on Freeway Driving Minor acceleration.. Moderiate to Full acceleration it's fine .. I've not been able to chase down an actual cause.. I just now do not drive it above 110Deg Outside Air Temps.. I'm Figuring it's #6 Cylinder water flow issue.. Next time the Engine is out, i'll check that..

I'm now chasing down the Cold Start Flooding issue.. When it's cold outside <30DegF, it will try really hard to flood and die.. if I keep the R's up for about 30 seconds it will clear it's throat and stay running at idle..
>~40Deg Mornings the Start is fine and I do not even give it a second thought.. <20 Deg mornings I need to keep the Idle R's up for about a Minute before all is good..
Presently I'm Pulling out Cold Fuel Enrichment VS Water Temp.. I'm scaling by about 1/3 presently up to 30C.. then I'm leaving the rest of that chart alone..

My other two Zeds ( Same ROM Code, also NA's) have never had this issue..

Anyone Else have to do this?..

Thanks..
