Everything is factory stock. Nothing bent or broken. Having that first bolt and linkage romoved didn’t cause the issue. I just removed it to give sufficient clearance for the video. Ive since removed the entire linkage and shock for servicing and taken more pictures that show where the bottom coil has been rubbing on the swing arm. Its rubbed through the paint on both the coil and swing arm and has surfacerust there. Its always been that way with this bike. I can’t seem to upload the photos, the upload function isn’t working for me for some reason?

Try again ? Images should upload fine on the site , if there is error , tell me and ill login to a regular account to test it.
Ive got 16 photos uploaded in the upload photo ‘bank’. Its that at its limit? Can I delete them to make room for more?

Photo uploading still isn’t working. Im using my phone and always have since I joined. Its been fine up until now.
Will test it now… as admin.
If it shows, its working on my end
I will login tomorrow as a dummy account to retest.

The bike looks really nice now mate, apart from the hazard you found. Don’t stress bro, i reckon you can sort that no worries.
Take some metal off the swingarm with a grinder, without creating a weak spot? If that’s not enough for clearance, take a bit off the spring too. Preferably just the swingarm. Could also hammer the CONTACT point on the swingarm but may not have the room to swing it with swingarm on the bike. Can use a diamond hand-file but it will take a while. Spray Rust-Inhibitor from SuperCheapAuto onto swingarm when you’re done. It’s almost the same black as the Hyosung frame. It’s a primer but you won’t need a top coat as it looks fine. idk where to get the red from. Maybe Ferrari.
Feel for frame to swingarm play/movement & check the connection at the TOP end of the shock for rust or bad welds or damage, bro.
PS. I’ll be buggered if i can get photos to upload here too.

Still not working. Ive sorted the issue out on my bike anyway but as the project progresses it is handy to post up a pic or two to demonstrate.
I found the error, i am working on it, will try to reprogram some code this weekend bare with me. My test account couldn’t upload an image, how weird.

LaserBeam, thanks for the compliment mate. Your suggestion is exactly what I ended up doing in the end. I had the shock and linkages removed for cleaning and servicing. There’s quite a few bearings in those linkages that needed a clean and fresh grease. All looking pretty much good as new! I ended up just shaving a flat spot on the bottom coil where it had been rubbing on the swing arm. Just the bare minimum to give it clearance then applied some rustguard paint to seal up the bare metal. All is good now! I’d post up some pics if I could of course!

Good news … except for the photos, (not your fault). I’m happy about that fix. I should be fixing my bike. Rear brake has been staying on since i got the bike & it’s toasted the disc. Haven’t ridden for a week & there was no MotoGP so i’m a bit edgey. I think the Rear Master Cylinder is siezing-up, but it’s a guess. I also lost a grub screw from the rear caliper on wet roads, so maybe water & dirt got in & is making a slider stick. Ordered an aftermarket Brake Master Cylinder & hope it fits the bike & isn’t rubbish. I never used the back brake this hard in my life – it’s been locking-up the rear and sliding up to the cars that pull out infont of me. Once the bike turned left & when it stopped sliding it almost threw me over the highside, to the right. Brakes … need those working, hey? 😉-----LaserBeam---->

Yikes, you definitely need brakes both front and rear working very well, this could a good excuse to overhaul the the whole brake system anyways

Finally I can upload a photo demonstrating what I meant at the beginning of the post. You can clearly see where the bottom coil had been rubbing on the swing arm. I’ve since resolved the issue by subtly grinding a flat spot in the bottom coil to give adequate clearance. Its only a tiny bit but its enough without compromising the integrity of anything. All is good now with all of the linkages etc cleaned, regreased and reinstalled.

My Rear Brake Master Cyclinder did SIEZE. It was full of rusty brake fluid. I couldn’t save it even after a cleaning. Fitted a cheap replacement and it actually works alright. Cost me only $6 Pounds. I know- what a bargain. Has a cheesey little reservoir & hoses but it’s working. I been riding in a thunderstorm just because the bike CAN be ridden now.
The rear brake staying on has been costing me about 20km/h top speed & a fair bit of juice. I rode for 2 days without the back brake – that’s a bit scary.

Good job bro. It looks like the bottom of the spring was also hitting the swingarm. It looks a bit grazed & rusted. Good thing you found that issue – would’ve made for a horrible ride & pretty unsafe. I been looking at mine just to be sure i’m ok. 😀
