Hi all !

1st post, thanks for all being here & sharing wisdom, much appreciated. Im in Seattle Washington, I've got a 1984 XT600 kick start. I picked it up from a neighbor who'd had it for the almost 30 yrs, sat in his garage for the last at least 20.

It caught my attention as he was trailering it down the alley to deal with getting it running so he could sell it, I noticed it had the exact same engine architecture as my 86 Yamaha SRX which is a pretty unusual bike so of course I had to buy it !

Well, long story shortened, after much cleaning of tank , carb, petcock, brakes, etc... I got it running, seemed to be doing ok but went back to it after a month & it'll only fire on its initial few kicks then its dead - no start.

When I first noticed a problem I was running thru the neighborhood, gone a few blocks then it lost power & died, able to restart & limp home then die.

went thru the Factory XT manual electrics flowchart & checked as suggested all components - the ig. coil - looked a little out of spec - replaced it, no difference. The Stator source & pickup coil resistance tests are as per the book ohm's so I bought a new CDI unit off ebay from a guy in Denmark, nice looking unit but no difference with that installed either. he's suggested its the stator, this is his message back to me:
" hello - this will be sure your stator winding !! is a very common problem !!
Just measuring does not mean that it is good!!

This CDI does not need a regulator or voltage to spark!! only the stator/pickup
willy"

Ebays translating dutch so its a little off I think but Im not sure what he means I should be checking.

Bottom line, it fires on initial kick or 3 then wont fire off anymore. Was thinking fuel issue prior to CDI unit so pulled carb again & its fine. W/new CDI unit it does exactly the same thing as OE CDI unit installed. New unit however doesnt light the neutral light in the gauge cluster as the OE CDI did.

Im open to any & all suggestions, am I missing something on testing the stator?
Or is it some other issue I should be looking at?

Thanks! Evan

hi
have no experience with older/cdi/kick only xts, so the straightforwardness of my question/suggestion might be more understandable - how is the spark itself? is it strong enough (visible in daylight as well) when being tested outside the engine?
