Help! Stubborn XL600
David Paul
started. The problem initially occured when I did not even get a spark
at the plug, so measured the resistances of the coils and the alternator.
Both had perfect values. After putting the bike back together I suddenly
had a spark (although I did not change anything). I just would not
describe the spark as FAT as everybody keeps telling me it should be (it
definitely is blue !). However, with this spark the bike is not bad to
start cold (4 to 5 jumps), it idles not toooo perfectly smooth for about
twenty seconds until it dies down...as if somebody stopped the ignition,
no warning, nothing. When the bike is warm (once it ran for about five
minutes without stalling, what a miracle) it is almost impossible to
start (at least I gave up). Now if I checked everything right the cables
and their connections should be okay.
Is my CDI fooling me ? Did anybody have a similar problem ? Thoughts ?
Suggestions ?
I am sick of staring at other bikers riding while I am walking.....help
me !!! You are my last resort...well, the last resort will be my Honda
dealer, but he already got enough of my money...
Thanks in advance

position not affect the stalling? If it is dying while idling, I'd check
the carburator, you might have clogged jet. If the throttle position
doesn't keep it from stalling, it's probably electrical. Check all the
connections, dielectric grease every single one. If still no luck, check
the CDI. My XR650 was having a similar problem, cutting out, stalling,
..etc., did all the above and it turned out to be the CDI connectors. $93
and a new CDI later the problem was gone.
Hope this helps you.

I've had to have my ignition coil rewound twice now on my '87 XL600. It
really ticks me off when this happens, but each time... The resistance
was out of tolerance. If I remember the origional post, he said that his
coils tested good. I'd still check the carbs.

Check the needle valve on the float. Damn Hondas.

Check the pistonrings or the fuel injector.

starts easy cold but doesn't when hot, the pilot jet is to rich. When the
bike starts easy hot but not cold the pilot jet is too lean.. Hope this
helps!!

Waaaaaaaaaiiiit a second here....I never read the original post
regarding your XL, but it is my understanding that in order to comply with the
EPA, ALL DSers are jetted lean.....articles I've seen on rejetting for
performance make HUGE jumps in some cases, to get the machine running right.
While the advice makes sense, I think going richer is the way to go.
Think about it: there's a reason why your idle mixture screw has a block on
it........and several other factors contribute to hot-start woes....when it's
cold, you have the choke to cover up the overly lean circuits, but when hot,
it's useless (and would cause bigger problems), or possibly your valves are
tightening up, making hot starts next to impossible.
Advice I've seen here that I'll support: Junk the auto-decomp. helped
my hot starting.
Criticism/Support greatly appreciated.

however we are not talking about a DS bike here that would be the
XR650L, but Honda does jet the bike slightly lean from the factory. I
would not go to the extreme try adjusting your idle screw first, then
if needed try the idle jets. The big conceirn which the poster above
was trying to convey was , MAKE SURE THE BIKE IS NOT RUNNING TOO
LEAN!!!!!! very harmfull on these big bore air cooled singles, or
any engine for that matter.
you also might want to check your idle circuit, I don't know how long
you've had the bike but it may be clogged or just dirty, does the bike
idle properly once started???
if the bike pulsates when idling, it's idle circuit is too lean
hope this helps..
