Something I would add would be a ceramic clutch plate (the next time the gearbox is out). They are almost indestructible, they work when they’re red hot, they work when covered in oil (if you blow a seal). You can rev to 5000rpm and feather the clutch out in 2nd to get going in deep sand without ever worrying that you’re going to burn the clutch out… it’s the first thing I replaced on my original monolever GS, then an 1150 GS and now my 1991 bumblebee. They practically last forever - I’ve never got near wearing one out including full trans-Sahara, trans-Congo etc.
Very nice information, thanks a lot. I‘m myself driving the 1991 gs and also had the shit in my pants because of the sidestand auto-snap situation. I‘ve had the sidestand modulated with a new spring set up and some welding. It works great even with the default sidestand.
This channel is absolutely awe inspiring. Your monolever airhead R80 with the Dakar tank looks so epic. And the quality of your content is through the roof. Your channel is going to blow up and I’m going to be there for the ride. 😊 Keep it up.
During the mid 1980s when I attended the Sydney Institute of Technology, I'd park my BMW R65LS near a BMW R80GS. I'd check it out and could never work out the purpose of this bike. Road bike, dirt bike, scrambler. What was it? Today, I'd have one at the blink of an eye.
@@bigberthaontour ha! Maybe this is where I’m going wrong 🤔😂 An 84 R80G/S, after some green lanes something has failed in the forks and I’m blowed if I can find the issue. It’s not like they’re complicated!! It’s sat sadly with its forks in pieces for many months now 😞

The hyperpro guys in Holland all ride pretty heavy duty trials with theirs and they all do DRZ400 conversion so they can’t be too far wrong. GS front end wasn’t a huge improvement although made it a bit more rideable off-road
@@bigberthaontour I am not the original commenter, but still wanted to give my two cents. The owners of HPN (Halbfeld and Pepperl) once tested all exhaust setups out there.

About real wheel size, the older models GS have an 18 inch. The more recent models have a 17 inch. I would like to fit a rear 18 inch on mine. Do you know if the old 18 inch rear wheel can plug and play on?
Sure I bought just the siebenrock foam on its own and that massively improved the comfort of my cheap seat. So if I was to buy the whole unit new I'd go for them.

Cheers for the optimism! Glad your enjoying but between you and me it’s a GS tank with some Dakar stickers on it! Looks nice tho :-)
Absolutely fantastic, mega interesting, you've inspired me to start putting my R80ST back together - thank you.
Great to hear, happy projecting and any questions along the way feel free to ask
@@bigberthaontour Thank you so much, you are a super star 😀👍
Yay another video love your vids thanks for doing content that I like

Well that’s awesome. I may well get back on mine this spring and start modding it for the roads out here. Must be a good vid if I watched it all! 😂👍

You must’ve been going some to do that! Good excuse for a new trick front end I reckon! 🎉
@@bigberthaontour well your DRZ comment did lift an eyebrow! 😁
this bike has inspired me to trade my klr for an air head, i have to have one.
It’s up for sale if you want it…one careful lady owner
@@bigberthaontour lol, from one old lady to another......
Love the bike, great video to boot.
I love all your madness! Can you provide some details on Stubbs bike? I have an R80/7 I’d like to thrash.
If you go to Rusty Nuts TH-cam he’s done a full run down on it!
Thank you very much mate…!! : )
Thx brother, from Belgium Bob
Could you provide the specifications of the Hyperpro rear shock. Following your video I am now hesitating. Initial intention was the Ohlins. Thanks

Had a very nice ST that sold last month. Was all original, so it would be a pity to do any changes on it or to make a GS out of it.
Yeah I'd agree, the ST is a nice bike in it's own right. Big Bertha came from a bit of a wreck!
@@bigberthaontour can you tell me where did you buy that extended rear brake part, please..!
@@felixs.a.3163 Hi Felix, sorry I don't understand which bit you mean, can you be more specific

Yes block your competitors with you Panzar, I like it.

@@bigberthaontour I refer to BMW boxer bikes as Panzer's (spelling) because they are big, wide and heavy.
A proper Y-pipe will be a huge upgrade.

Hi Owen what size anakee wilds would fit on the back? suspect 120 max?
I had a 120 on there, looked pretty snug!
Owen, I see you have a mudflap between the rear wheel and the Gearbox/battery. What is it and how did you attach it?
Mate I have no idea where that came from. It says triumph on it 🤣 but it seems like a bloody good idea!
@@bigberthaontour Hahaha, glad you discovered a new feature on your awesome bike!
Why not better forks? DRZ forks work very well but need specific triple clamps (available on adv rider)
I guess I wanted to keep it roughly in keeping with the parts of the time. If I did it again I’d probably go down that route
@@bigberthaontour DRZ forks and ‘Prutser’ triples work great on an airhead, completely changes the ride
Did it originate as a monolever or did you convert it? I didn't think monos existed until 87?
Both the original ST and G/S were monolevers, paralevers were the ones that came in at ‘87 and have the additional torque arm underneath
Everything’s G/S on this ST 😂
I think it says ST on the reg documents, that’s about it!
Hello, I've mounted a Migsel stand. easy to install and to maneuver. the spring have two position: automatic retract or not.
Cool I’ll check them out
Finally bought one, bloody expensive but it is very well made. Cheers

Sorry that one is beyond my knowledge. Wonder why they downsized...
@@bigberthaontour To make it more "roadable"
@@garyhoward4064 ah yeah that'd make sense

Btw I’m the first one to watch
Well done Iori, now if you can get through all 19 minutes without falling asleep you definitely deserve a prize!

What kind of headlight did you put on?
It's just the standard ST headlight. I've got a grill just taped over it to protect the glass
