I joined the club a few day’s ago so I thought I would introduce myself. My name is Nigel, I am 63 and live in Grimsby, North East Lincolnshire. I recently retired from work and decided to get back in the saddle and put abit of fun back into my life while I’ve still got time ha! ha! I bought a new GV125 Aquila back in November 2017 and I am quite impressed with it. It has been around 40 years since I was last on a motorbike, so I chose the smaller 125 engine to see how I got on. It is certainly alot of bike for the money. I took the bike back to the dealer whom I purchased it from, for it’s first service earlier this year, but I am not confident that it has been properly carried-out. The dealer is about 20 miles from where I live, so obviously the engine was hot when I arrived. They only had it for 2 hours when they rang to say it was ready to be collected and charged me £75. I have since learn’t that the engine has to be cold before certain item’s can be checked and if necessary adjusted, like the valve clearance for instance. When I went to collect the bike I asked for a service checklist but was not offered one with the comment that they do not issue one anymore because the service is logged-in on the Hyosung web-site. Can any of you guy’s verify that ? I have lost confidence in the dealer now, so will look around for a recommended mechanic elsewhere for item’s to service that I am not sure of myself. I don’t mind getting my hand’s dirty and do some maintenance myself that’s within my capability, so is there a service manual I can download from somewhere ? I am really enjoying being back on a motorbike, the sense of freedom and being in control of the machine is alot more satisfying than driving a car. I have found your blogs to be interesting reading, especially the tips on maintenance and up-grades, of which I am sure will come in handy in the future. I will sign off for now and wish you all a safe ride.

Welcome to the site & forums. I hope you are also part of the Facebook group below too:
There is quite a lot of GV125 and GV650 owners popping up this season too. It’s not just hyosung sports bikes being famous now!
Moving on, let’s talk about your garage/dealer first!
For me with just a couple of years experience with the Hyosungs (knowing how every part works) I can honestly say this… Your dealer is an idiot.
If you have a bike under warranty for that matter, everything has to be recorded. What happens if you were to sell it and how can you prove what has been done and what ?
Also, they must tell you WHAT justifies spending £75 on what ? I can almost 99% assure you, they work on “budget” basis, basically they use WORKSHOP OIL (cheap artificial oils) …. Yet the manual says use GOOD premium oil. There is a lot of moving parts & bearings in these vtwins. a lot! Good oil, filter, o rings goes a long way
Myself, I do travel to some distant places to rescue some GTR bikes as a mobile mechanic, I can stress that it is always good to check everything on your bike if something is off. It’s good to address it before it gets worse! That saves a lot of bills in the long rung and a happier bike when the owner stays on top of things.
I’ve seen too many mechs take shortcuts, it doesn’t take long for each owner i meet to have a long rant about how they got ripped off in some places and ended up worse off lol.
I’ve never lived in Lincolnshire personally, so i wouldn’t know who is a true bike mechanic.
Ask in the Facebook group, as there is many lads who live there but most actually do the work themselves by following manuals.
To be fair the Hyosung’s literally last quite a long long time even 10 years @barry650 has one. On his 650, all he did was change regulator for aftermarket ones to keep the electrical system happy, the rest was just regular maintainance. Ive had a 125 Aquila that was 51K and 2005 reg. Old girl still had life in here!
My local dealer services some Aquilas that are usually 30K on clock, you can tell the owners have been riding all over the place without killing them.
Speaking of that, check out the links below for service manual & “owners” book.
Service = more detailed / Owners = common things to do.
So i say read all links, remember GV/GT250 engine works the same way as 125! – Just bigger pistons & a larger cooler. Same valve clearances / same timings.
(Download the “2003 Onwards” models):
SERVICE MANUAL (ENGINE WISE)
(Download the GTR & GV250 EFI SERVICE manual) – For detail engine work/ specs.
Coming from a guy that once spent 6 months average tinkering with his own cars in the past, I am glad to say “I agree with you Nigel , biking is just better”
Cheaper , more satisfying when things are sorted & more LIBERATING… (I am sure @bigtrev1969 can confirm this haha , i know how much he likes tinkering with this Aquila by himself , than trust some chinese to do it, i had to mention him!)
Ride safe fella. Hope this info helps you, if there anything unsure of, just let us all know!

Many thanks for replying to my enquiry with regards to the dealer. My brother said exactly the same word’s to me as you did, but when face to face with a so-called professional who tell’s you that they don’t issue service checklists anymore, I was’nt going to put him in a half nelson and demand one ! On one of my rides recently I came across another biker who recommended a fully qualified motorcycle mechanic (Ben Adgie) with some 35 years experience in the trade. His business is 20 miles away (only a further 5 miles on from the idiot dealer !). When I get the chance to speak to him, I will ask if he issues a service checklist and if he would be willing to work on my bike. I have downloaded the owner’s and service manuals (thank’s Marcel), at least now when I do some maintenance on the bike I’ve got some reference to work to. I have alway’s looked after whatever vehicle I’ve owned and am keen to make sure my bike is as well. I am going to order a new oil filter and ‘O’ rings and change the oil myself, I’ll be sure to get some decent oil as well. I’ve clocked-up 1200 mls and according to the owner’s manual the next service is due around 2500 mls. Will I be okay to leave it till then to get the valve clearance checked/adjusted and anything else that’s not within my capability. I can do most thing’s myself and other’s, if somebody shows me first then quite happy to “ave a go”. It’s a pity you don’t live abit closer to where I am then I could call on your service’s Marcel, anyway you’ve got your day job. I have been interested in the recommendation’s re: up-grades such as coil, fuel lines, engine mounting bolts etc. Would you suggest I leave it till something play’s up or up-grade as & when I want to ? Many thanks for your help Marcel, going to sign off now.
A safe ride to you, regard’s Nigel.

That’s cool, let us know how it goes with the new mechanic in the future, but i think i am confident you can be able to keep most tasks done yourself.
Keep receipts of whatever you buy & save it in a book somewhere, it’s something I do in case i have to sell it, i have receipts of whatever parts have been added & the mileage at the time.
Valves are checked 600 miles, as it’s important to ensure the engine isn’t tappy, ratty or loose cams etc… The first 600 miles gives the chance for bike parts to mature up inside and mesh together nicely
So after 600 miles, it would not be surprising to see some metallic shavings on the oil , once you do a fresh change.
How many miles do you do each week anyway?
Speaking of upgrades, honestly speaking, the mind is the limit but based on various feedback online, i know these mods are the “most obvious / most effective” upgrades meaning you will notice it outright & perform way better.
- 520 Chain Kit (Converts 428 chain to a fast 520 chain system)
- Large Kawasaki regulator
- Kawasaki ignition coils
- NGK CR8E IX or Laser Iridium plugs
You can read more about the first 4^ popular upgrades via the shop link below:
GV Aquila chain kits are a custom order, (no one does 428-to-520 kits besides myself), so send me an email!
5. Then also importantly (stock or modified bikes) – Upgrade carb jets to one size up…
I have written a full tutorial below , so you can see how the process works.
Easy to do! (if you need jets, just send me an email or ask your mechanic)
Your carb is Mikuni BDS26-DOUBLE

Thanks for your advice as regards the 4 upgrades and that will definately be a job for me to do this summer. Have ordered the Oil filter and Iridium spark plugs so as soon as they arrive I’ll get the oil changed and just see if I can tell whether the dealer has changed the oil or not. From what I have read up on the difference a 520 chain kit can do for performance sounds really worthwhile, as well as the regulator & coils up-grade. You mentioned the fact that if I want the 520 chain kit I need to email you, is that because the club shop does’nt stock that item for the GV125 Aquila ? Once I have got the regulator & coils fitted I’ll then see about getting the 520 chain kit. You asked me what sort of mileage I’m clocking-up. Well, while we’ve been having this good weather I have been trying to some seat time most day’s, and that usually turn’s out to be a 30 ml round trip. So in a week I could be doing 150-200 mls. Now that you know this do you reckon I really ought to get the valve clearance checked/adjusted ? I’ll give this guy (Ben Adgie) the motorcycle mechanic a bell and see if he will work on my bike if you say I ought to. Many thanks again Marcel, will email you when I’m ready to go for the chain kit.
Ride safe, regards Nigel.

Hello. Yeah just email me about the GV chain upgrades. Its a special order as 520 rear sprocket is custom made in the US 😉
So it will be a game changer when many gv riders have done away the fragile slow 428 chains.
Your parts have been sent. Expect them tomorrow hopefully.
Valve clearance schedule is:
600miles (1st service) , then every 4,000.
I hope your mechanic knows his way around hyosungs (they are still a suzuki intruder engine but evolved better by the Koreans).
Lincs isn’t far. If you need me , just give me a shout , be happy to show you how things done anyway & what to watch out for etc..
Have a good week!
