Have now pulled all plugs and they're all sooty already. Test ride was worse than ever. Very lumpy. Wouldn't idle. Needed to be in lower gears than normal. 30mph in 3rd would stall it. Had to keep revs up and in 2nd or 1st at 30mph. Throwing me all over the place. I've tested all spark plugs and they're all reading fine. I did pick up a spare from Halfords when out on the test ride.


Strange it ran so smoothly in the drive after I pulled and cleaned the first plug. As soon as I pulled away though it went very jerky. Unrideable it's so bad.


It's dark and cold out now so calling it a day. I might try and look at starter valves syncing again tomorrow with the plugs all clean to see if having done it before the plugs were cleaned caused me to set them wrong with something mis-firing at the time I did it.


Also got through 1/3rd of a tank of fuel today in 24 miles (usually 50 to 60). Fuelly measured fill up at the start of the day gave me 31mpg for the previous tank. Today will be lower than that! Something is definitely wrong.
