- Has it had valve clearances done? (can’t be avoided)
- what modifications does it have?
How about the other 2 points above ?
In regards to the carb, I don’t know if you can but can you take out spark plugs and upload on this site ? (Add media button on the reply box)
We can see if its running rich and which cylinder front vs rear.
I rarely encourage messing with the air mix screws for many reasons unless a pro is good with the carb especially multi cylinder carbs , one engine can run a little richer than the other etc to aid in cooling as is the case with hyosungs and maintain some harmony
So, do you think its possible to disassemble the carb and then give it a clean (air compressor as OEM books say, and some liquid cleaner or some guy to do an ultrasonic clean job, probs £40 for the job if the carb isn’t so bad.
Least with an open carb its not just about cleaning clogged holes, how about slides being too scratched? torn? slide springs too tired? slide needle has been wrongly set in the LEAN setting ? (hence why I’d like to see your plugs)
Be ready to change plugs either case. to new ones.
Coils , Caps, Regulators are 3 common things that wane on hyosungs but lets do fueling out of the way , as it’s hard to attack many things at the same time. Dealing with each part / section of the bike will narrow issues down 1 by 1 . Any form of boggings , poor running is always either “valves too tight/too loose” , “fueling from the tank the carb inc pump” vs “sparking power” (plugs, coils, caps these 3 are married) – Regulator can just as easily slow things down a bit, again , electrics after the fueling is out of the way.
