Id guess its seen a harder than usual life. New rings yes, but new piston within 4 years indicates either a seizure or more hours than average especially since covid means its really only a 2-3 year old bike. Some people say around 500 hours for a piston on a trials bike but this is totally dependent on what kind of 500 hours On the other hand it could also be just be an owner who stays very on top of servicing

A 9 year old tyre will be as hard as the rocks. A new tyre run at 4 or below in the mud will make a lot of difference. The fact that you've had a 300 before (granted it wasn't he freshest) and didnt find it too powerful in the dry makes me think you may be disappointed with a 200. I always urge less experienced riders away from 300s because they get away from them, but i wouldn't just because you are struggling to find grip in the winter. I vote 250. 7 in the front is also high. especially on worn tyres. Maybe you're trying your best to avoid punctures, but in mud going, max 5.5 in front, max 3.5-4 in the rear.

If you're going to use epoxy, use epoxy metal, eg jb weld. Anything like araldite will break down over time exposed to petrol

At least you can swap components over from the runner, to diagnose what's up with the non runner

Easy to be 'professional' when you're the richest team, by far

I guess you won't know until you have them started. Good chance the clutch pack is stuck if they've sat long. You could test this without the engine going. Main bearings might be a bit rumbly, but again you won't know until you've started them . The 03 and 04 have non repackable exhausts. Absolute nightmare. Your bike will no doubt sound crap because the exhaust has never been repacked. Some people cut them open to repack, but its a lot more than a hours work. Make sure theres gearbox oil, radiators topped up and fan is coming on before you start going too far Otherwise, just the usual stuff, headstock bearings could probably do with a greasing and maybe rear linkage bearings. Good chance the latter have a lot of play by now, but that won't stop you getting out and riding them. PS, check the sherco rear disc for cracks. If they even still have the genuine discs, the disc arms were very thin and prone to cracking

If you're being spat off a 20 year old rev 3 you're going to spat off pretty much anything

I had a couple of scorpa sys with no linkages in it. Great suspension and absolutely no need of servicing. I love my GG but the rear linkages are an absolute disaster.

Any jitsie dealer should be able to source one. https://www.jitsie.com/en/content/24-dealers#us Vertigo also use the same sprocket. Did you check these guys? https://www.trialstoreusa.com/front-sprocket-gasgas-vertigo/

The 300s i feel are softer at very low throttle openings, they have better torque which makes them nice to ride. Anything beyond 1/4 throttle and they have more go than any 250, most of the times too much for a clubman. If you like your beta 250, then id stay with a 250. Most 250s across all the manufacturers have similar power delivery

Its personal preference to be honest. Personally id always favour a newer fresher bike

The first time you yank the bars up hard, like before a splatter, your hand will fly off the bars

Thats a more difficult question lol. If you're an expert rider, have the spare money, and like an extra bit of bling, yes. Otherwise no. After all its only really the carbon airbox, better rear shock and a couple other small engine pieces. Ive never had one, never felt the need, but im always cash strapped

See here, seems your friend is correct

The only slight weakness of the gearbox id say is when the shift lever return mechanism or 'top hat' breaks. This is usually only through rough treatment and also an easy fix. Ive had 5 ggs since 2010 and never had gearbox problems yet. Sometimes the clutch plates need modifying to get a perfect clutch, but cant say ive ever had an unusable clutch. Never heard of frames rusting, only rust ive had is where your boots rub through the paint at the footrests. Dog bones are a pain, but this is pretty consistent with most bikes. Hidria ignitions can be temperamental, but these are also used on other brands so not necessarily as GG related problem

Didn't think they were built particularly bad before the takeover, any specific part you are referring to?

yeah i think ajp are 25 mm. Any ajp or braktec cylinder should fit, the lug mountings are all the same

Im 6,2 and ride with standard bars. Definitely go back to standard, 95% of trials riders run standard height bars

Can you not source a second hand part?

Current path being to the ground via your thumb and feet which i imagine were on the ground when you were stopped. Soaked clothing and boots i imagine would greatly reduce this paths resistance. Where does the lcd negative line go or is it earthed to the bars?

I don't think any of the above occur more frequently than in any other sport tbh. Theres a few pros who ride with knee braces (ferrer, farre etc) Theres also wrist injuries, specifically the scaphoid. Some american and Japanese riders ride with full face motocross helmets, but in my area ive only known one person to fall and lose a tooth in 20 years riding

Ah right. I wasn't 100% sure, just checking that you knew there was a possibility. I came across this post on here It shows the last time @bigmark1972 was online was 2017, so i doubt hes much help lol. May be worth contacting XIU https://www.xiu-rdi.eu

Is the clutch spring not the same as a gg?

I wear jitsie trousers and they are relatively loose. Not super tight anyway. The knee pads i have are these https://www.pocsports.com/products/vpd-air-legs probably on the minimal side regarding mtb knee pads but they fit no problem underneath. All depends whether you go down the tight fit route or the slacker fit. I know the tighter fitting mots trousers have knee pad inserts that fit into a pocket inside their trousers, https://www.motsracing.com/products/pants/step-5/ however an alternate looser fitting pair like these https://hebo.com/gb/inicio/669-4980-pantalonpants-trial-tech.html have no real knee protection and you need something underneath. The last hebo pair ive linked seem to be really popular at the moment for older guys who don't want skin tight trousers
