I have added the stainless steel caliper rebuild kit to my shopping cart. If it will for certain work for my 2008 30th anniversary GV650 then I’ll place the order to night.

Jul 5, 2025 at 8:17 PM in reply to: Can You Parts Swap Between Suzuki SV650 and Hyosung GV650 ? #19923I have spent days dredging the dark corners of the interwebs and found nothing but cloned websites of cloned websites.
I was concerned about the stainless piston rebuild kit as there is a warning sign next to the GV650. Something about it only working on the silver and not the black calipers. I have the black rear calipers on my 2008 GV650 efi

Having to look up parts based on what brand of machine it’s bolted onto rather than the part itself is very frustrating. It seems the Tokico 2 pot caliper is used on loads of older bikes.

This is beyond annoying. Why the hell won’t anybody list the physical dimensions of the product?
I am still riding with just the stump of a broken footpeg because either the listing doesn’t include the pin and spring set, doesn’t include the physical dimensions, or both.
I can manage with a missing left footpeg around the city and without a passenger but only for short hops around town, and without a passenger. I’ just frustrated with the lack of brick and mortar, physical parts stores.--==I have come to comfort the disturbed and to disturb the comfortable==--
Unrelated
My front left-foot peg broke and I need a replacement. I see a tonne of “Universal” footpegs on eBay.
Could you point me in the right direction? I don’t care about keeping it OEM, so long as it is decent quality at a decent price--==I have come to comfort the disturbed and to disturb the comfortable==--
I’ll get the photos off of my phone for later. I ordered them and at first was a little concerned as the packager was significantly smaller than expected.
Thankfully, they do fit, they do line up well enough. The only real difference is the heat shield for the front cylinder, the one that runs under the rider’s right foot, is a bit shorter. This isn’t an issue, it just doesn’t wrap around as far up underneath the bike as the old one.
I’ll get some photos up here soon.--==I have come to comfort the disturbed and to disturb the comfortable==--
Seems like I am out of luck, unless you know a tuner that can help.
I’ve emailed a dozen shops and nobody seems to be able to help.
Follow-up question.
Will the exhaust heat shields (consisting of 5 pieces) from a 2016 GV650 Aquilla Pro fit my 2008 GV650 EFI Anniversary Edition?
From the photos they look identical but I’m unable to find anything online to verify whether they are a direct bolt-on or not--==I have come to comfort the disturbed and to disturb the comfortable==--
Running an aftermarket exhaust/ slip-on “can” or “silencer” really shouldn’t make a difference. Regardless, if you’re still running lean when up to operating temps it might be a good idea to pull the bowls on the carbs to check the floats aren’t sticking and there’s no bits or gunk in any of the ports/lines. Also, if the bike has set any lenght of time before, or after purchase, it might be helpful to purge the tank and fuel lines.
I’m glad you’ve got it rideable
P.S. The bang-and-pop is a thing some riders like and why they switch to aftermarket slip-on exhaust.
Best of luck
Cheers,

Fair enough. But have you solved the original issue with stalling at lights? Still hoping for some advice on the stalling at lights issue. I have added some Liqui Moly Carb and valve cleaner (as mine is not an EFI). I added that, filled the tank with E5 and took it for a ride before taking the exhaust off, but there was no improvement after 20 miles. Perhaps I should have mentioned that I bought my bike with an aftermarket exhaust fitted, but the original exhaust came with the bike. I asked a chap at the local Triumph dealer if an aftermarket exhaust could affect smooth running and he said it might, so I thought I’d return the factory exhaust to the bike. On removing the aftermarket one I found it had a great big crack at one of the joints (hidden from view) and the front cylinder fixing was loose because the gasket was missing. When a new gasket arrives I will be able to see if the factory exhaust improves it at all.
Does your carby GV have a manual choke?
--==I have come to comfort the disturbed and to disturb the comfortable==--
Ohhhhh boy!
Yeahhhh, any changes to intake or exhaust will change the behaviour of the bike. Increasing the amount of air in (For instance via K&N high performance air filter) or the amount of air out, such as after market exhaust, will have some effect. Typically it will cause the bike to run a wee bit lean as it’s now breathing better.
For starters, there is an Idle Adjustment thumb screw. You can adjust this to set the default idle to run a bit richer. It will idle high til it warms up to operating temps, but that is the quick fix solution.
https://www.manualslib.com/manual/1018449/Hyosung-Aquil-Gv650.html?page=24#manualDepending on the increase of airflow due to after market intake/exhaust you might need to change your carb needle jets
If you really want to get into the weeds of carby tuning I found a tutorial from Marcel
[Tutorial] How to adjust Carb Slide Needle (Tuning) – Hyosung GV & GT 125/250
Honestly, the aftermarket slip-on should not make that much difference. It might cause it to run a bit lean, just as a high performance air filter would do. The quick fix, once all your other issues are sorted, is simply making sure your spark plugs are properly gapped, your air filter is clean, and adjust your idle up to run a bit rich

I would prefer to stay with belt drive but the only belt I can get my hands on here in Scotland costs £300.00
I can get 520 O-ring chain anywhere and it’s way more affordable--==I have come to comfort the disturbed and to disturb the comfortable==--
I’ll do that. I have given the bike a full top to bottom cleaning and full service. I did this immediately after purchase. I’ve been riding big twin cruisers since 1995. My current GV650, the first bike I’ve owned since moving to Scotland from Texas eight years ago, is the first Sports Cruiser I’ve ever had (I’ve always had a traditional style cruiser. Such as the shaft drive 1400cc Intruder), and by far one of the smaller engine sizes I’ve ridden, let alone as my primary daily rider.
I’ve never before encountered these types of gearbox issues.
I am grateful the GV650 comes stock with forward controls giving the smaller frame a more comfortable riding position. It did not occur to me to clean and lubricate the forward control shifter linkage.
Hopefully that will help resolve the issue

I installed the standard X-Ring chain conversion kit. I believe it came with 16T front and 46T rear sprockets. The chain that came with the kit is 520 “Heavy Duty” JT O-ring.
Ideally I’d like to get a 6-speed gearbox fitted (possibly from an SV650?), but if needs be can make do with adjusting the ratio. I understand it will negatively impact acceleration, which sucks, but will also lower my RPMs at motorway cruising speeds, which is what I need more than off-the-line, red light to red light acceleration.
--==I have come to comfort the disturbed and to disturb the comfortable==--
Does the X-ring conversion kit offer just a smaller rear sprocket or just a larger front sprocket? I’ve been considering changing the gearing ratio by dropping a few teeth on the rear sprocket. As far as the gear ratio goes, either increasing teeth on the front or decreasing teeth on the rear should have the same effect.

Jul 5, 2024 at 1:32 PM in reply to: [How to Tutorial] Hyosung GV650 ST7 Front Drive Pulley Removal without Belt / Chain Conversion #13983Thanks for the heads-up. Though I’m afraid I may have the opposite problem as I over torqued the front drive sprocket nut but will definitely be keeping an eye on the entire assembly. The X-chain conversion fitted perfectly without any fuss, but I’m still a tad nervous about either of the sprockets coming loose. Not really a fan of chain drive but it is the best option for a GV650 as old as mine. Definitely will go through every last nut and bolt before getting a Stage 1 ECU tune

This is what happens when an East Texas cowboy and a Highlander wrench on a bike in a Glasgow car park.--==I have come to comfort the disturbed and to disturb the comfortable==--

These are the new rear shock absorbers.
I’m working on getting them dialled in. Ride, adjust, ride, rinse and repeat. Haven’t quite hit the sweet spot but I think that’s a rebound not preload issue. The bladder is very finicky and just checking the pressure can bleed of 10 PSI.
I tend to run with pretty well loaded saddlebags. Finding a sweet spot that gives me good cornering as well as a comfortable ride both with and without panniers, with and without pillion, is proving to be a bit tricky. I’s rather err on the side of the suspension being a bit stiff when solo and no panniers as I’d rather not hassle adjusting preload every time I throw my saddlebags on or happen to have a pillion.I have not yet addressed the forks. They have not been touched from factory. Not overly excited about having to do a teardown and replace seals, but they are sounding like they are dry

Question
I also have a GV650 EFI.
Do you reckon this K&N filter fits the GV650?https://www.knfilters.co.uk/su-6503-replacement-air-filter
--==I have come to comfort the disturbed and to disturb the comfortable==--
I’ve never had a new bike. Always bought used, rode hard bikes. Unfortunately, unlike back yonder here I don’t have my own workshop. My Brother (Not blood related. Ride or Die Brother) inherited all my tools when we moved. We relocated with only two checked bags each. I’m slowly building back up my toolbox.
The biggest struggle acclimating to Scottish/ U.K. life is “Where the hell do I buy stuff”. Automotive parts and accessories just aren’t readily available over here and just about everything I need has to be got online.I spent the afternoon installing new rear shocks only to discover the tire gauge I bought online doesnt fit the Schrader valve on my wheels or suspension dampers. I keep running into seized bolts, and was unable to remove the front drive pulley because I don’t have a big enough socket nor a breaker bar. I don’t even know what size socket I need.
So I can’t tune my rear shocks. (which is a two-man job anyway) I can’t prep the bike for the chain conversion today for lack of specific tools. My front suspension is making a noise now like it’s dry or a worn seal and I really don’t want to have to rebuild my forks.To top it off, I’m doing all this work outdoors in a shared car park … it’s been a long day.
Do you happen to know if there is a PDF or video guide for the X chain conversion installation?
--==I have come to comfort the disturbed and to disturb the comfortable==--

I’m an idiot.I bought a trolley jack from Tool Station for 32 quid. I did this the day of finally finding and ordering the X-ring conversion. If I had just spent a few more hours searching online I could have had this.
Well if I’m being charitable with myself, I had just spent a weekend working on my friends van, in the rain, to then ride an hour home, in the rain, to then snap my drive belt a mile or so from the flat and had to push her home, in the rain. Then i spent three days being a ball of ADHD anxiety trying to find a replacement belt. By the time you came to my rescue with the X-ring conversion kit I was done in. I’d already spent three day freaking out over how much this “simple” bit of basic maintenance is costing us. I am hyperfixated on every penny we are having to spend. So when my nesting partner came into my office and said “What all do you need to get this sorted? Whatever tools you need, just buy them”
My brain was absolute mush, fatigue, sciatica, arthritis, that spot in the middle of my lumbar I can’t reach any more from the two times I broke my back, I was done. I couldn’t see spending 60 quid on a jank metal hoop that I could absolutely do a better job of with scrap metal and a bit of PVC for the roller. So I just blurted out “I need a floor jack. There’s a floor jack. Sorted” 😀Last night I found this, on Amazon. It’s too late to return the trolley jack and order the bike lift in time. Parts should be here tomorrow, and it doesn’t hurt having a trolley jack.
Live and learn.
With a new rear tire needed before winter and having spent monies put aside for that on the chain conversion just means I won’t be getting the bike jack til sometime next year, hopefully.That’s a really rambling way of saying, I found a decent looking bike lift
If I had just waited
