Why not get a pair of panniers and a top box a la BMW. You could then put all your stuff in them and carry it all around the sections. Don't understand why we don't see more of this sort of thing.
On the Sherco rear-tankers, there is a long plastic fuel line, perhaps 60-70cm which runs from fuel tap, up to the top of the fuel tank, then back again, with various bits and pieces attached, including one-way-valve, breather, tee piece and fuel pump. This fuel line will develop small holes and cracks which cause erratic running, fuel leaks (apparently coming from the carb or pump, but not) and other weird and wonderful issues, which you will attribute to the carb, fuel pump or Brexit. ALL of this fuel line needs to be replaced every couple of years if you want your bike to run properly. It will only cost you a few quid. Just make sure you put everything back together correctly, especially the one-way-valve.
In England most Trials are held on a Sunday. with only a few on Saturday, whose arrangements often differ from the following: Trials usually start at 10.30. Usually ten sections, 4 laps. No break. It depends on numbers and sections, but they usually last between 3 and 4 hours. Cost is usually between £15 and £20. Number of riders can be anywhere between 40 and 100, with 60 - 70 most likely. There are usually 3 grades of difficulty: Expert, Clubman and Novice. Most Trials may have both Modern and Twinshock bikes. If you are going for the first time enter the Novice. Watch what the other riders do and follow them. Most importantly, don't take it too seriously and HAVE FUN!
I think the Greeves Challenger was a Scrambler, not a Trials bike. It might be a bit too lively for Trials, even with lower gearing. However, I regularly see two pretty original looking Greeves Anglians with leading link front forks, Villiers engines and the cast aluminium front down tube being ridden in Classic Trials, on the Middle route by experienced riders in the south West of England. They are as good as me, if not better!
Had a rev 3 200. Now have an Evo 200. Beta have not changed the engine characteristics much at all. The older Rev felt like it had a heavier flywheel but I never bothered checking.
The 200 is the ideal entry level/beginner.
If your screwing up on one of these then you probably shouldn't be riding trials
What year is your Beta Evo 200?
I have spoken to several VERY experienced riders in the south of England, Expert, former Expert and Clubman riders. These have been riding 2019 models and new models purchased in 2021. They have ALL complained of the same characteristics, which are that the engine spins up too quickly. A side by side comparison with the flywheels from a Beta 250 and a Beta 200 shows that the flywheel mass on the 200 is substantially less. Additionally, there is no tapping for an S3 flywheel weight to be fitted.
Bikes have been cured by fitting a flywheel from a 250 and an extra base gasket. Possibly other mods too.
Never mind the comments about screwing up from the galah, my question remains; why did Beta ruin the Beta Evo 200 and do the latest 2022 models still have the lightened flywheel and raised compression?
The Beta Evo 200 was much appreciated by older riders, who wanted a softer, less aggressive power delivery.
Can anyone enlighten me as to when Beta ruined the Beta Evo 200cc by lightening the flywheel, raising the compression ratio and other "improvements" which have spoilt the soft, mild, tractable nature of the engine, making grip elusive in difficult conditions, even for experienced riders?
The 2020 models still had the above "improvements". Do the 2021 and/or 2022 models also suffer?
The B40 is far too heavy. A Bantam is much lighter and easier to handle. Why not buy a Bantam trials bike that just needs tidying up? Even better advice would be to buy a modern 125cc trials bike and learn to ride that, rather than ruining an old British bike.
its all assembled with the new piston and barrel but the original cam chain is now too short. I measured the height of the new barrel and it’s slightly taller than the original 125 one hence the old cam chain just fits but is way too tight even in its most loose setting on the tensioner. The kit is Berlit.
so I guess I need an extra link or two longer can chain?
where to find one?
has anyone else experienced this problem?
any help or advice gratefully received,
kind regards,
Andy
If you search the web, or e.bay, someone sells 100 link cam chains. The one I bought was branded "Tour Max". However, I cannot remember where mine came from. Here's one here.

You have a Yamaha TTR clone, Jianshe engine. (Chinese, part owned by Yamaha). Videos on Youtube for fitting a big bore kit.
Replace the 130 main jet in the Mikuni carb, with a 150.
