The GV650 EFI started in 2008 2 ECUS (1 normal and other was made in Japan) because in 2008 we also had special aniversary edition red frame GV650 models, also last generation (around 2013-2020) we have DELPHI ECU using Delphi Electronics and revised fuel pumps , and the upcoming GV650 Pro will be DELPHI electronics again.
ALL EFi models are OK , it is just regulator was problematic , so we upgrade to Shingden Regs and Electrosport Stators (like you saw on this website’s shop pages)
Later EFI models (Delphi) use slightly smaller diameter stators , they work OK. But still recommended to change regulators to a beefier one or replace OEM one as soon as they start acting funny. Many fake shingden regulators online, so it is better to go to a local junk yard to find a wrecked Honda (too many models to list).
Hope this helps.
KRMotors has it on their website 🙂 and Sinnis will freely give it to any UK customer when they ask
I will upload it eventually on this website as i have other languages due to many EU users visiting this forum (ie. Spanish language for Spain) , i just need to find time!
They came after “hyosungSparesUK” was shut down due to scams. So this is another scam website!
Avoid any website out there that is usually blue & white because it is by the same person including “AU, NZ, wholesale, catalogue, eu, etc…”
This is based on many reports of angry people online.Are you confortable using standard car jacks x2 , to lift the frame on both sides instead ? and you can wind them down slowly when done ? Sissor jacks are what we use on GVs due to most of the “So called hydraulic lifts” are too high to slide them under the GV frames as the GV’s are low slung machines unlike the GT’s
£60 for what you saw in your picture is expected or more but any bike shop locally can get it for you since they already have trade accounts to get it from wholesellers ?
Oxygen Sensor in the exhaust
Engine TemperatureThese two can affect how much fuel mixture the ECU provides to the injectors.
Have you tested them ?
I would also keep an eye on the ISCV unit (idle speed control valve)
Try the TPS though and let us know and use E5 Fuel (RON 99) is best. Here in EU with E10 (10+ % ethanol content), the bikes hate it. Less ethanol is better.
That’s why our GOV in UK advises us for older motorcycles to keep using E5 (aka. Shell VPlus Premium) or pure unleaded (rare)
https://www.gov.uk/guidance/e10-petrol-explainedThe codes in the books are used by dealers to tell Hyosung which panels to send if rider has a crash or needs replacing ie. For Black rear panel, we would say send us “12435HG12345-SBK” = SBK Black code for some GT bikes.
On the Hyosung GT bikes, the red is different , and the closest car we found is Hyuindai Electric Red (not 100% but almost there) , took years and 1 guy took a gamble to share with us all.
So i am not sure which Korean car would use the same paint as your frame.
Bodyshop was the way to do it. They needed the bike with them to match paints (or try to)
Yes it is physically attached to the tank from underneath
It overflows to the road, and it is also a breather pipe (vent) , so let guide it on the frame until it faces the road.
You might have to use a mini dremel steel disc and cut the mushroom top of the nut off, then slice it down,
Replace with 8.8 Stainless Acorn / Dome Nut of the same type. Don’t use open nuts as the water/weather may try to corrode the threads.
Let us know if that worked out!
Marcel got me fixed up ! Thank you!
You are welcome!
Stay in the club and ask away , least our public replies will help others coming across similar issues of anything.
be sure to do a project journal 😉
Did you change the black piston slides inside the carb?
What jet sizes are you running ? (pilots and mains)
Have you modified the air intake in any way ?
Adjusted the float height?Trying to rise the revs and it cuts, sounds like the slides got stuck or bad mixtures (fuel mixture screw tampered with) or jets possibly too small (unless clogged again)
is it a carb model or EFI?
Do what happens if you go up to 6000 rpm very slowly?
Explain the “uneven behavior” more ?I’ve clearly got to get some mechanical issues sorted, but this winter I’d like to start addressing the frame rust and flaking paint. I’m also going to delete that unnecessary hunk of plastic attached underneath rear fender. Do you happen to know where I might paint match for touch ups? I can’t seem to find the Hysoung paint codes for the 30th anniversary edition (#86 of #1000. Yeah, bit of a brag)
Hyosung doesn’t usually say the exact codes as they use inhouse paint. Maybe a local body shop can closely match it for you and mix in a spray can if you desire ?
On this SECOND picture, is the pipe dangling down physically attached to the bottom of the fuel tank or is it coming from a carb ? Try another picture ?
it comes underneath the tank on the right side and doesn’t go anywhere but petrol comes out of itThis picture, are the pipes attached to the fuel pump itself going the right direction ? I could be wrong but it seems like fuel is going to the bottom of the pump
Usually the PUMP itself has arrows for fuel flow direction and it looks kinked on one of the pipes , could explain running issues too.
Maybe rotate the pump again ?
Also i still can’t see which pipe is leaking fuel , maybe lift the tank and hold the pipe while getting a picture?

I assume you got your answers already by now , but i will say Korea doesn’t always like things to mix and match or attempting to cross breed everything
Even with EFI, the 250 and 650cc have about 5 variations of harnesses and ECU’s! So even a 2008 EFI won’t fire up with a 2016 ECU simply because stators changed, pulse timings changed, different pressure pumps, and all the like, it’s a whole deep world of its own. Carby is easier to maintain , EFI is snappy & instantenous
Darth Vader black theme really suits it personally , i can’t see you changing colours anytime soon.
As for the italian cans, are they loud enough for your neighbours ? If yes, then drivers should move out of the way for you 😉
Any motorcycle will make us break the bank if we don’t stop lol. You should see Bandit 600 riders, they can drop easily £3K just to rechrome everything and trick everything but it is still a “Blandit” , i think the Hyosung GV650 is worth the cash & most comfy ride! – I like the new shape harley sportsters sub-cruisers/bobbers but i won’t still buy one or ever! – I’ll rob ideas and put it on the Korean damsel instead 😉
Keep going fella 👍
beautiful girl , really like the limited edition red frames & the cherry wheels, don’t divorce it 🙂
as you have guessed , Scotland is a bit colder than Texas! – So indeed, keep it as clean as you can, this island is wonderful for its green orgasmic sceneries but not the weather!
