Bike Model = : EXIV250R/GD250R
A few post back I made a post about the 400 mile GD250R I took in recently.
Slow crank would not start. New battery. Found the factory ground (battery to engine case) appeared to be placed on a painted engine cover. Horrible spot beyond that it is in between the frame and engine. Added a clean new ground and the bike fired right up.

Quoting your previous post
”Bike Model = : GD/EXIV/ 250rHi! New to the group after buying/selling hundred of bikes over the years a Hyosung has eventually ended up on my lift.
2017 GD250R/EXIV 250r only 400 miles has not been started in about a year.
First thing I replaced on it was the battery. It cranks slow. Have tested and tried a handful of known good batteries so it is 100% not a battery issue.
have checked nothing else, I will start with frame/engine grounds, starter solenoid and then starter.
any input from other owners? I just want to acknowledge how cool it is this seems to be an active forum. Almost all bike groups have moved to Facebook at this point and I don’t think it’s for the better.”
=========
Have you considered removing the flywheel to check the condition of the sprag clutch ?
But looks like you fixed it though , gotta love electrics! – Apply some ACF50 and clean wires, incase of oxidization after all the years , did the owner ever ride through a bad storm ?

But looks like you fixed it though , gotta love electrics! – Apply some ACF50 and clean wires, incase of oxidization after all the years , did the owner ever ride through a bad storm ?I think it was just a matter of sitting with low mileage for a long time. What little connection it did have at the ground probably oxidized over time. It was in a standard garage in the northeast US with no climate control, no major corrosion anywhere on the bike but the ground is pretty tucked in and low so it’s possible. Added a clean larger gauge ground wire as the stock one is pretty thin and long. That was ultimately the fix for it. Runs and rides great will be going through it with basic stuff like changing all fluids, and torquing/thread locking major bolts.
I’ll read up on threads about what these tend to need “out of the box” i am assuming the same kinds of things you’d want to do with most cheaper produced bikes. I think for someone in the market for a cheap first bike this spring it will be a great deal.

Will you not keep her? She looks stunning! Do like the aggressive brawny MOTO3 vibes it gives out , think its the best looking sports bike hyosung has done and such a damn shame it was shortlived as its bigger sister GT650R was more preferred by most riders and the GT250R funny enough due to them having vtwin motor instead of the GD’s unique single piston 250 motor block. Its definitely faster than a GT250R by a small margin if both bikes are factory untouched (no mods)
As they say, “look after it and it will continue to serve you” , get busy , Spring season right around the corner now 🙂
