my 16v kr seems to rev hard on cold starts sinse it got colder ...it will rev to 2500 ish on every cold start,it then settles to 1100 after a few seconds..a few people said its normal but it seems too much??

what does yours rev to on a cold start?

 

ive checked

isv,temp senders,flap height in airbox,thottle switch,idle set up

 

cheers for any help

if you mean idle, myne starts at about 1500-1800 then sits at about 1000!

 

hope that helps

yeah thats what i mean...so judging by you mine revs way too hard

anyone know how to alter it?

When it's idling at 2500rpm, tap the idle valve with a hammer and see what happens then. If it drops to 1100 straight away, try cleaning the valve out with some carb cleaner and then a little WD40 to keep the valve lubricated. A KR should idle at 1100 when cold and then 950 when hot.

 

Your base CO might be out too. KRs run best at 2.0% CO.

no..its no a faulty isv...it goes to 2500 on start up then gently settles to 1100 ish

 

wouldnt the c/o need to be miles out to cause that?..anyway it idles at 900 with the isv disconected

OK, around the thermotime switch are 3 temp senders. One of them (blue/white wire from memory) controls the idle speed. Check the wiring here.

 

The idle should be 1000rpm with the isv disconnected.
