Hi all. After having the carbs off the engine I have run it for a short while and checked the plugs. They are running lean, white deposits. to richen them up do you just turn out the mixture screws 1/4 turn at time? I can get access to an exhaust sniffer.
Depends... the mixture screw adjusts the idle circuit, if it's lean on the main jet, then you'll need to go up a size!!
cheers Paul. how do I tell? It was jetted on the rolling road so I am assuming that the jets should be fine.
As long as you've been on the RR, then it should just be the idles that need a tweak!! Another way of checking the main jets is to drive at 55/60mph, switch off the engine and coast to a stop, and pull a plug out and check the colour!!
Cheers. Thanks. The last journey was just a short trip to work. only 4 miles and back. It wont have even got warm. Stop start traffic also.
