[QUOTE="Colin, post: 160549, member: 1953"] Thanks Bruce. Yes in the early 80s I built "The Arbuthnot Iron" a Comet trials for The Arbuthnot long distance trial but also entered in the Talmag. and a number of one day trials with my trials club Southampton Vikings. In my first entry in the Arbuthnot I had a rigid rear suspension as was then required but the Organisers made me run in the telefork class as they considered Girdraulics far superior to ordinary girders. I ran a 60 tooth rear sprocket, forks in sidecar position, and a specially made bash plate&, high level small silencer. I seem to recall I cobbled up some stronger ATD springs to keep it a bit retarded unless really revving. Apart from ditching as much weight as possible it was otherwise standard. If you could stick it on, it would climb the side of a house. It flogged on however I abused it but, it was really too heavy &, too wide for a trials bike but i had fun and , won the odd award . The building of the bike and subsequent rides were written up in MPH around the early 80's One thing it was very good at was the tie breaker. Accelerate from one line and brake hard to stop on another some fixed distance away. low gearing and four brakes were the winners. Shortest time wins tiebreaker. I have photos somewhere and will try to find them. I briefly rode Ron Kemps Trials Special at a Talmag event and it was far more agile, and lighter than the "Arbuthnot Iron" but my aim was to be as close to a standard Comet as was practicable. .At one trial as I parked up to walk a section, some one came out of the crowd and gave me a massive "telling off" for daring to treat a Vincent in such a manner. Good job he had not seen the previous section, as I had up ended it. in a sea of mud and it had taken me and a couple of observers about ten minutes heaving to get it out. It never broke down, never failed to start, and never let me down. wish I had it now. If you can look up the articles in MPH [/QUOTE]
