Starting troubles
« on: Sep 11, 2017, 01:07:12 »

Didn't know where to post this so it's going in here. So my bike has been having trouble starting,
sometimes it's hard to start cold like this morning I was trying to go to work and it was really hard to start. Then when I was leaving work it started right up... then I let it warm up and restarted it. it started fine, then I drove it home and turned it off and back on just fine, tried again and it was hard to start.... any ideas? I this problem went away for almost a month but now it's back and idk what to do...

Have you checked all the left hand side connectors for corrosion?

All the left hand side connectors look okay. Should I buy electrical cleaner spray and spray the connectors?

had the same issues with my XS 750 which was converted to your later transistor ignition.

1)check your battery voltage, if its under 12v you will not get proper spark.
2)thenI would check spark on all cylinders.
Do you have fat nice spark on all 3 cylinders?
3)if there is no spark on some of the cylinders I would cut a bit off the ignition cables (1cm) and then put them back into the spark ignition coil.
swap around ignition coils,check the plugs on the coils.

My issues were a combination of bad connections in the loom and a bad ignition box.

1st plug(left)
2nd(Middle plug) it was super gunky ...
3rd plug(right ride)
Looks like I have a strong spark on the first. And an eh spark on the third but the middle is a little rough. Probably because it was dirty....what's really weird is that whenever I'm testing spark on one the engine fires up(with the other 2 cylinders) like every time...but I put it back in and it won't start again...i can't really do your other tests yet since I have to ride it to work...yay for kicking the engine 50 thousand times, unless I get lucky! Battery had good charge I think it was at 17

So you're saying cut these back and plug them back into the connector since there is a weak spark?

NO.  He means the HT leads  where the plug cap is screwed on.  Often the ends of the sires inside the cable are broken off.  Remove the pug caps, cut 1/4" or so off the leads and screw the plug caps back on.

Though the circled section doesn't look too good, either.
