Slow action throttle probably the easiest and cheapest. Check what's on it now, white throttle tube is fast, black is slow.

NGKs are useless once oiled

In the picture you attached it says 4T 09->13 so surely that means its not a simple bolt on to a 2020

Thats not true. Don't ask me how long warranty is though lol. In america the official GG warranty is 30 days, not sure about the UK, but ive heard people get their GG fixed under warranty up to 6 months before the switch to KTM. That could be the specific dealers warranty though. Not sure who the official uk importer for GG is these days, used to be john shirt, but pretty sure he's not anymore. Also a damp van should not cause electrical problems. I guess you could count yourself lucky you've diagnosed the problem if you do end up having to fix it yourself

You don't need to grind the riveted pin before using the breaker. Any half decent breaker will force out the pin as it is

When you buy a new chain and you need to shorten it to fit your bike

Didn't think trials was a big enough market for people to make copies!

Silicone spray is usually the go to for leaving a nice shine after a wash (gt85 is pretty popular) although it won't really remove any residual grime as you call it as it wouldn't be as liquid as wd40 (unless you properly douse it in it) I wouldn't say the wd40 is actively dulling your stickers. Although the silicone can revive dulled stickers through scratches that looked beyond restoring

Motul 10W40 (what i use too) is going to make your clutch anything but snatchy. Switching to anything lighter will most likely make it more so

Gotta kick it from the very top too. If you depress the KS a few inches and kick from there, most likely it won't start. Unless you're tall this can be rather tricky with your left foot on the ground

Most trials bike come with regina as OE and if not maintained i wouldn't say they rust less or more than any other respectable brand of chain

I don't know, i think you would need a good bit of heat applied. And maybe don't do it while its on the bike, wouldn't want you breaking one of the mounting lugs

99 and 2000 had different exhausts. 01-05 all had the same exhaust and mudguards. You have the right mudguard for your bike. They did run close, but didnt obstruct as much as yours is. I think your exhaust has just had a good bend upwards over the years

Just from a 10 minute ride on a vertigo id say its geometry is more towards my GG than a beta. Pretty sure the betas are the steepest steering wise

I wouldn't worry about engine internals, although the gouging can get bad enough after a couple of years that you think the kickstart end piece might break off. Never has with me. My latest bike ive put a piece of heavy fuel piping over the kickstart as you said

Im surprised you need heavier, id say im about 90 kg and never bottomed them, then went to the techs and they are softer. Maybe the latter are more progressive. Anyways, jitsie used to make them, although don't list them on their site anymore. https://www.thehellteam.com/40mm-marzochhi-heavy-spring.html Heres a link showing what they used to be, but sold out on this site. Maybe worth contacting jitsie

If its free play you can reduce this at the lever with the adjuster, half an inch is closer to standard. Or is it 1.25 inches of sponginess?

Not an expert on osets but running a 24v motor with a 36v battery will eventually burn it out. But since your problem coincided with the chain getting wrapped around it, it sounds like this has been the cause of some internal damage.

Not really. I always end up wearing a jumper or a thin fleece between my shirt and outer jacket. Even the professionals when training just seem to wear a hoodie or something so there must not be what you describe from their sponsor or else they would be wearing it. I think jitsie do a gilet type thing that is supposed to add a bit of warmth without the need for being waterproof. Other than that i guess this here is as close as it comes https://www.jitsie.com/en/jackets/53275-jacket-polygon.html Just wear two of them lol

What is it with all these KTM fanboys? ? Everywhere i go this is all i see. There are differences. Granted not a lot. PS why have you got an orange sherco? ??

Not an expert here but as far as i know the hub/spoke layout hasn't changed since then, whether its a flanged rim or non flanged rim front or rear. So anything from 03 right to 2020 should fit as long as its 32 spoke. And this is across all brands!

Sidis are a good boot, although they have tendency for the sole to start coming away at the toe after a couple of years (not the stitching, just wear the sole is glued to the stitched sole.). A bit of glue re attaches this before it gets worse. Gaerne i feel offer very little protection. The sidis are a stiffer boot, much better protection IMO. I went for the same size as the gaernes and they are tighter, but passable.

Is that Arizona, one of the 3 states that have higher infections rates than any other COUNTRY in the world?

A bike that age i cant imagine much being wrong. Check that the clutch isn't draggy and maybe give the gearbox a run up to 6th and back
