Ian Mackenzie Posted March 10, 2018 Share Posted March 10, 2018 I used a colourtune on a BEC with a ZX9R and I got it through the SVA so it worked for me.CheersIan Link to comment Share on other sites More sharing options...

Ivaan Posted March 11, 2018 Author Share Posted March 11, 2018 Had a play over the weekend. 3 cylinders sparking well but showing yellow, 4th with very weak intermittent spark. Stripped down the coils / leads, and found quite a lot of corrosion. All clean up, and trimmed ends on the leads.Now all 4 sparking well. Managed to get at the two outer pilot screws only, and adjusted them to correct " Bunson blue".I then removed the carbs and checked the settings. The two adjusted were within a quarter of a turn of each other, so I've set all the carbs to the richer setting. Then tried to balance the 4 carbs, but again access to the adjusters is nye impossible. They're all pretty similar, so have left it for another day.Had a run this afternoon, and she's pulling well, with a good pick up and nice idle. I'm sure it could be better, but I need someone with tiny asbestos hands to access the screws!Clive Link to comment Share on other sites More sharing options...
