Info Video on Pilot Air/Fuel Screw Adjustment explanation.

Quick update. Did a little bit of fine tuning yesterday. Ended up going leaner by half a turn on the pilot screw.

Went for a ride this afternoon and what a difference that made. Bike goes much better now. Also smoother with noticeably less vibration throughout the whole bike.

Before the adjustments, I could feel the vibrations through the fuel tank, foot pegs - the right footpeg being quite bad and the handlebars - which was why I added the heavy bar end weights.

After going another 1/2 turn leaner, the overall vibration throughout the bike has very noticeably decrease a large amount. It's only just noticeable now even at 8000rpm (100kph in 6th gear). Bike revs very nicely. Revs drop to idle with no hanging over idle or dipping below idle. Choke works and I can now take off in 1st gear without revving it up too much.

About the only thing I might be tempted to do now is to change the needle height slightly - just to see what happens. Again, the bike isn't a fire breather, but is now running noticeably much better than it was before.

Now to try and sort out that temp gauge. But if not, I might buy a cheap digital one from ebay/aliexpress. I've already checked and cleaned all the electrical connections on the temp gauge wiring and @Murdo installed a new temp sensor and thermostat during the build - so that rules out those parts possibly being faulty I would think.
