Thanks, Slim, I will do what you recommend.
We are racing in the US this summer and I looked at all of the options. Safety is a big issue. The track at an all-bike meet is likely to be in better condition. It is not torn up by heavy and powerful cars. Last year's Speedweek got me to thinking about this. So, we are signed up for Delvene's first meet, as FIM, partially streamlined, 1000cc, naturally aspirated, twin cylinder. The record is 159+ and we have done 140. Some serious hours and hardly any money, 'cause I do not have it, is going into this year's attempt. Things are looking good. Torch and hammer work, mainly, with some can tipping, that is the big plan.
