It's probably a 200 cc whitehawk, instead of short studs and sleeved head bolts they had full length studs and ordinary nuts on the head. Have a look at the spigot on the barrel, if its very thin its a 200cc barrel
Wow lookat the torque curve ln the gas gas, near vertical from about 1500 to less than 2000 rpm. I've found the gas gas 300 pretty rideable actually, the 300 beta however i find tiring to ride, be interesting to see the figures for it.
May not be relevant but worth checking, had similar problems with my Evo, when i took the trigger/ pick up coil off to check the stator there was a lump of dirt/ grease on it, i cleaned off with solvent and lo and behold everything was fine again
As someone who rides motorcycles almost every day and also an agricultural quad with thumb throttle every day, I can't say i notice much difference in "controllability ". I will say though that in the situation described I use the clutch rather than the twistgrip on my trials bike to "check " after blippkng over an obstacle, still I applaud your inventiveness
You could try the universal bar risers off flea bay, they clamp into the existing mounts and then the bars clamp on top, the have removable inserts to allow for normal or fat bars
Maybe of interest to folk with fibreglass tanks, Esso do an ethanol free fuel, 99 octane, i think its called synergy 99 it is ethanol free in most parts of the uk, but not all so check your area
Just did a quick google check, here is the official blurb What is the ethanol content of your fuels? ... Esso super unleaded petrol (Synergy Supreme+ Unleaded 97 and Synergy Supreme+ 99 ) is ethanol free (Except in Devon, Cornwall, North Wales, North England and Scotland).

Beta: The perennial issue of Betas jumping out of first or second gear - mid-section! Some do, some don't - will yours? Glass mudguards.
Sherco: Rear fuel tank models 2012 - 2015 - fork yokes hit frame downtubes and chop through/collapse them. No longer an issue. 2016 only = fiddly air filter and awkward radiator filler (can be overcome using hypo syringe). 2017 onwards have a different clutch, which might not be easily adjustable.
TRS: Don't really know, but I have read about different issues.
Seen this mentioned before, all I can say is I've had 5 betas over the years, never had one jump out of any gear, and never had to replace a mudguard either. There are a lot of beta's in my area too and never heard of anyone else having s problem, strange?
Have a word with Steve Bamford at Casa Monte's trials holidays. He is in Andalucia, I remember him saying Spanish license is very expensive, 3 to 4 hundred euros, think he used to ride under ACU license ?
Not sure if it was the same problem, but a mate of mine rebuilt my front wheel for me with new nipples on original spokes and he said he had to run a tap through the nipples to get them to fit properly, he made the tap by cutting a slot in an old spoke!
Check the throttle slide they are soft metal on the Bing carb and wear quickly and can then jam, especially on full/ high throttle openings....I know from experience ?
