So my 04 is dead

(1/3) > >>

SMPKX500:
Took out my 04 K5 Thanksgiving weekend and after a quick warm up the bike started stalling. At first thought it was fuel but quickly ruled that out.
Changed out the plug with no luck. Kind of think its the CDI unit but I'm not sure. The coil could be going as well.
Anyone know how to test the box? Who has them for a good price? I remember replacing one on my 250 once, wasn't cheap.

KX500freak:
what color has the spark?
how bright ?


about testing ,it can be done i think,dunno how exact
but you don,t have a buddy with a kawa ,then you could try his cdi first

SMPKX500:
Well I kicked it over with the plug out grounded and got no spark. But then when I put it back in it started for a minute.
That's to problem. It will run for a minute maybe two but then it just shuts off. :oops:

KX500freak:
hmmm sounds also a bit like to rich jetted,
what jetting do you run ?
what mix ? 1:40 is my mix
does it stall whatever revs you,r making?
or just above idle?
anyway check the plugcable too ,maybe loosend a bit .
and what plug brand /type ?
some plugs can fool quite fast if jetting is off
i have denso and twinspark and jetting okay ,never fools plugs

SMPKX500:
Its not a spark plug issue. And I have never fouled a plug. I run a NGK BR8EG. Stock jetting. Sometimes it will start, run perfect then just die. I think its the CDI unit. If it were the coil it wouldn't be intermittent.
Are the CDI the same though the years or do they change?
