Update: (apologies for formatting, written on mobile)
Just got back from my friends and it’s running much better than before. Acceleration is smoother, it doesn’t sound nearly half as unhappy and she can now idle rather than stalling out.
We opened her up and took out the carbs, gave them a solid clean using plenty of break cleaner, unclogged the jets and that seems to have done the trick.
She had an issue with the air to fuel ratio, and we’ve temporarily remedied it by drilling a small hole in the bottom of the air box to help her breath a little better.
Replaced the plugs with Iridium NGKs, the front block was a fun one to figure out.. 🙃
There doesn’t appear to be any rubber bungs in the carb adjustment screws which leads us to believe that it has been tampered with before, so to have the bike running 100% I’m going to have to get them aadjusted by a professional.
The new battery I fitted a few days ago hasn’t died since charging it, so I believe I misdiagnosed the reg/stator. We ran the battery dry today constantly starting her up during the testing process.
Jumped the bike off another battery and it maintained power after the ride home, so happy days.
So I’m happy, the bike is in a much more rideable state and touch wood, everything seems fine.
The last demon to work out is the fuel level sensor, its currently flashing on empty. I traced a yellow wire from the loom that plugs into the tank and blasted it with break cleaner but that didn’t seem to do the trick unfortunately..
Thank you for all of the advice, it is much appreciated.
