Although not to do with twin engined bikes but I did mention above some time ago I'd like to have a go at top speed runs on my Hayabusa Two Faced; well I finally managed it. First runs were in August and I manged 180mph at Elvington, but in September 2012 I went there again and clocked four runs all in excess of 190mph with a best of 196.6 mph. Normally aspirated. These runs can be seen on YouTube at:- http://youtu.be/P3iOnGyMfZs I hope you don't mind me posting this here. I don't think my original Two Faced double-engined Triumph's engines would have stayed in one piece long enough, on their 98% nitromethane fuel diet! Cheers for now. Pete
