Sorry I can't help with the problem , but just to say a great big thank you to all you 3 wheelers for coming along and putting on such a good display.
You were easily the most exciting vehicles on the track, and two of you (I suspect you know who) were having a real ding-dong out there which was really great to watch, it only finished prematurely when one suffered an engine problem coming out of the chicane in the afternoon runs. Originally I thought his spirited driving onto the rumble strip had dislodged the front wing and the smoke emanated from the tyres, but I suspect it was rather more serious.
I will post some photos later once i have sorted through the 200+ that I took throughout the day.
