Post pictures on your next reply by clicking “ADD MEDIA” green button.
So we can see and verify which pipe it is. A few pictures would be best. (where it starts from and where it ends)
Hey,
Buy these ones and bend the pipe slightly (!) , and it will 100% fit your engine (it says 250 only because it is shorter that’s all, so expect to use a longer hose ?)
https://www.ebay.co.uk/itm/255440961047All GV’s from 125cc up until 650 had “optional upgrades” of center stands, saddlebags , crash bars , – The center stands seem pretty rare nowadays , i even need one myself for other GV’s i own.
Custom made can be done for sure, but will cost some money to your fabricator that does custom work on choppers , just make sure it can support the weight of a 200+ kg loaded machine!
Hey, open this topic below, you will find CDI diagram for 125cc carb model GT125R , it is 10000% the same as GT250 carb model. They use the same CDI
Needing a little help with my current project (+GT125 CDI PIN OUT)
Is halfords near you? Get a bottle called WYNNS FORMULA GOLD PETROL , strictly this bottle only as i rave about it all the time. Redex is just junk.
Pour the whole bottle inside.
Make sure there is about max half a tank inside (less diluted if the tank is full) , ride until you reach 1 or 2 bars as long as you are within proximity of the service station to refil.Use e5 fuel only. They don’t like E10 at all.
Use fresh CR8E spark plugs from halfords during this.
Report back and let us know if the “soft cleaning” has helped your entire fuel system (incase there is debris all over the fuel system from tank pump right down to injectors) , yes a pump that’s bad will make a bike run very rough , vise versa to the clogged injectors too.
If not, are you able to download the service manual on this forum that corresponds to the year of your bike, and follow the instructions to trick the ECU to output any error codes (past or present that may be stored in the ECU)
Externally, remove the “GOLF BALL” that is near the airbox system with 3 or 4 pipes sticking out of it going from airbox to the throttle bodies , this is your “Idle Speed Controller Valve” (ISCV) , it is what controls idling when the bike is at closed throttle (neutral) , sometimes this object needs replacing. There is a few versions , so take pictures , i may have spare ones on ebay of these ISCV’s
Check your regulator is 14v idling (13.5 absolute minimum) to 14.5v max and the voltage doesn’t drop when revving to about 5,000 rpm ish
If it does, replace the regulator , unstable voltages will make the whole EFI system haywire , unlike carb bikes that can still chug on , but EFI likes the electrics delivered pretty consistently
Keep an eye on this topic too, it may relate to you a little bit i hope
Hey, i noticed the topic was a duplicate of this one below , i will reply there instead 🙂
Welcome!
Post a picture of her 😉
I hope you keep her for a long time, they are fun machines.
I’ll hunt it down for you and do you want me to email you ? or will you email us first ?
I believe Startright Motorcycles have it (oldest hyo dealer in UK), but i can’t confirm yet, so give them a ring tomorrow morning?. They are on Google Maps, so their number should come up right away.Hey, Sorry I could not fully understand what you were saying, the translator i use is very rubbish. Is it possible to send a reply in English and upload a video (youtube, instagram , dropbox etc) copy the link here.
Maybe we can see what the issue is with our eyes too. We have a few 650 owners on this forum and one of them did a good ECU Diagram in tutorials section.
There is also the service manual in this forum, find one that matches your ECU / Year of bike = > Get error code and tell us.
Then add pictures so we see what’s going on. (Vacuum tutorial is already on the forum too GT & GV are the same , except GV has a manual tap that’s all)
Sadly , you need to ring your bank and get refunded. All “Hyosung Sites” that look identical to the WholeSale one , are scammers sorry.
See this topic
Have you looked on ebay ? you will find my shop for used parts under the name @evocrest (click here) , also ColchesterBreakers isn’t too bad , also ring our business partner STARTRIGHT MOTORCYCLES (oldest hyo dealer) and let them know Marcel sent you , can’t comment on other ebay sellers as i heard reports some sellers are just straight dodgy, so be wise on that platform.
Overseas ? I sometimes buy stock from SunCoastCycleSports USA (i trust them) , for fixing customer bikes on my private workshop , they seem to be a major USA hyosung seller. Can’t comment on other USA places , never tried them (or care to)
Europe ? Ring RacingPlanet UK first (they have warehouses in EU) , confirm stock first as their website doesn’t always show things. In fairness, last time i ever used them was in 2016 haha , then i moved on to other supply chains in trade & stocked my own stuff now.
If not , i can order new parts for you, just send us an email at the bottom of this site.
I responded to your email regarding the sprocket tensioner , not something i generally come across to be fair , and most of them are chinese made, so i am unable to verify their quality or how well they tension the chain
Small motorcycles probably (50cc/125cc can get away with it with their 428 chains) , but the beast of a GV650 running 525 chain. I mean if you find one that fits properly from Amazon (not ebay) , if its junk, Amazon will take it back free and your money is back. Expect trial & error
Based on that picture, i would say if it tried to say E41 , the code doesn’t exist , so C41 would be correct. Why the ECU keeps saying C41 despite a replacement good harness, will now suggest injector woes (you did say it runs rough, it won’t idle for too long).
So the injectors may just be wanning, i’d still keep an eye on the fuel pump though , as the same error applies to it including any wiring to aforementioned parts.Also check your ISCV unit with the service manual to make sure it’s working properly as it does control idling when throttle is closed (idle speed control valve / ISCV)
Is the bike running normally now ? and have you been out on it ?
I’d say it’s not a bad call to replace the injectors and re-check the wiring between injectors + pump back to the ECU, but i believe in regards to wiring you have been through it enough times.If it helps , I can always do a chain conversion kit for you as a local stockist just email us , as most of my 650 clients use chains now until their budget allows them to go to a belt system again (at that point, it’s good to change the pulleys, keep old ones as spare)
If i ever find a way to source a cheaper belt in the UK from my traders, ill be stocking it on the website like crazy , has to be good quality , none of the china crap that snaps in 2 days.
Some ECU’s might moan , as the fresh air pumped from the airbox might affect the 02 sensor readings back to the ECU. So i would caution this.
With that being said, I did have a customer 2011 Delphi bike with 2x 02 sensors (i know 2011 and a delphi?) the engine had no AIS system whatsoever not even a plug for it, it was as if Korea saw no need for this particular bike not to have it , then i had a 2008 Sentec ECU bike that had 1 AIS system feeding the rear exhaust where the lambda sensor was.
I don’t believe a gauge can just die , it is rare on a GV , you would need to re-check the harness that is sending all the signals from the blue connector plug and the red wires.
Even the “Right KillSwitch” , actually should at “least” turn on the green lights for the RPM & MPH dials ?
I wish i could see a video of the bike running , and you turning the lights on and off just to see what happens to it and revving it. Black/Yellow wire actually tells the RPM counter what to do.
Speed Sensor = Goes straight to the dash on the MPH side.
Use the link below to make a new topic as it will be easier this now. It might be beyond fueling issues etc, so making an individual topic specific to your bike could be easier for everyone to follow / reply to. Again, if its not fueling , then it will be something else deeper in the engine 👍
Not a problem. Glad you sorted it. I gotta say i respect your creativeness!
Have you actually opened the fuel gauge display in the middle so u can see the wires that end up inside the digital circuit boards
The red wire or grey wire might be split in 3 so that it shares power to the rev counter and the mph gauge also.
I hope you don’t need new clocks!
