In Brazil, we've encountered the same problems involving the regulator. The issue is that the wiring connecting the regulator to the battery is too thin; this problem can be solved by switching to a larger gauge wire. Simply follow the red wire that goes from the regulator to the 30A fuse, and then to the starter relay. A good practice is also to change the connectors. I particularly use a Deutsch DTP for both connections (stator and regulator). It's also a good idea to change the TBI connector to a waterproof one. If water gets in there, your bike will shut down. Another source of problems regarding ignition may be caused by the spark plug connectors, which here in Brazil were pretty trashy. Water gets into the cylinder head and messes up the spark. A good solution we've found here is to change to another style of connectors.
I had a similar situation with my Versys 650. I found out too late that the very early models (like mine) had a weakness in the weatherproofing of the Rectifier/regulator electrical connector which meant the plug would corrode...and then fry the rec/reg. It's a lot harder to reach on the Versys than on that Hyosung but I got it all changed eventually but before I plugged it all together I packed the plug with dielectric grease, and then fashioned a waterproof boot out of an old cycle inner tube and cable-tied that around the plug. Thanks for the video - enjoy your holiday!
I just got one of these bikes used and I have been working on it and I have to save these videos have saved me a lot of time specially since its my first bike so I had no idea what I was doing
I've had the red warning light come on everytime I started the bike. You mentioned something about that being associated with the voltage regulator. I noticed after a ride if I got caught in the rain have persistant electrical issues (starting). Finally lost power to the instrument cluster on a short ride. Fuse blown. Seemed obvious to me the voltage regulator was no longer regulating. I suspect after a wet rain water was dripping down past the frame onto the wiring loom with a major group of connectors bunched together. The rubber shroud was poorly designed and the seam/split facing upwards. Ordered a replacement regulator on Ebay. Also I'm going to revisit the shroud and attempt to improve the setup to enhance protection for these connectors so I don't damage another regulator after a wet ride. I think the oil you're seeing on the connectors is somebody else's attempt to stop water ingress into the connectors. I'm thinking after all dried out, cleaned up, checked use a few layers of electrical tape from top to bottom. Could do each connector seperately.
Yes, you are spot on about water and electrics on this bike, that was the whole problem from the start, and you could be correct about the oil on the wiring, was maybe grease originally and has watered out with the wet weather. You are on the right track improving the setup and looking for all the spots where water can get in. Sorry it took a while to respond,, been so busy at work of late.,,, Cheers
Best thing I did to mine: (1) REPLACE the rectifier RICKS Motorsports One (2) replaced with Ricks Stator (3) LiTH battery. (4) removed the SMOG/Charcoal Canister. Smooth as butter
Hello mate I have gtr125 Hyosung, it’s giving me some ecceleration problem, when I give it a full throttle it’s start dying. Any idea what can be the problem. Thanks
from what I have been seeing online, you are more better off soldering the wires together rather than having a removable connector. it makes it more waterproof and prevents dust, gunk or any other foreign build up occurring.
