So K3 has ~31,000 miles. It's done some weird things, such as feeling like it's turned off while riding, then I twist the throttle and power is back on. Still wondering if its in my head. It's also just died for no apparent reason. I pull over, thinking WTF, then it starts back up.
I recently came back from a trip and when I went to ride, the battery was dead. I jump started it and figured it would just charge up on the ride. Well, after a 30 minute ride, I got gas and it wouldn't start. There was a nice hill, so I just roll started it.
This was also super weird, I was racing a friend, kinda forgot to shift... Went to redline, bike didn't like that. Lost power, saw F1 flash on the dash, and rolled to a dead stop. While I was slowing I was trying to fire it back up but it wouldn't start. Sat a few minutes, turned it around, and got roll started (thank fully, cause that would suck to tow).
Rode around some more, then had an opportunity to charge the battery on the charger. I believe the battery is good. It was at 12.65 volts after 2 weeks of sitting and I hadn't put it on a charge since the last time I limped it home.
Okay, so I went through the service manual...
The battery current leak was about .3 mA (with in spec of under 3 mA).
The regulated voltage was low, appeared to be battery voltage @ ~12 V (suppose to be 14.0-15.5 V @ 5,000 RPM).
Measured the resistance of the generator coils, they were 0.2-0.9 OHM for 2 legs and OPEN to one of the legs
(all suppose to be 0.2-0.9 OHM).
Measured generator no-load voltage of ~65-70 V and 2 legs ~40 V
@ 5,000 RPM (suppose to be more than 65 V @ 5,000 RPM)
All the measured values for the regulator/rectifier were with-in spec.
Another couple things I noticed... When I bought the bike, it was leaking a little oil from the stator cover. I removed the cover, cleaned the surfaces, then applied high temp silicone gasket maker, fixed the leak (but am thinking that someone was in there at one point). The R/R is aftermarket and looks cheap, cause when I went to test it, there was no coupler, instead it had all 5 wires were individually soldered together.
So, I'm assuming that the stator is bad. The R/R appears fine even though it's jimmy rigged and electrical taped together. Should I just replace the stator/generator only or also replace the R/R?
Has anyone had these weird problems? As always, any input would be appreciated!
This is a pic of the R/R, everybody like pics.
