Hi. My name is Andy Heitman and I live in Smalldole West Sussex. I have owned a small off road motorcycle business, situated at Golding Barn Raceway in Smalldole, this year we celebrate our 33rd year in the game.
My son Sam who now manages the business rides a Triumph Metisse mainly with the Pre65 club. We have had many enjoyable years racing MX but only in the last two years have turned to classic racing after building the Metisse from scratch mainly to fulfil what I can only describe as a late mid life crisis, Sam humouring me agreed to race it, as a result we both have gotten the bug!.
The Greeves class at Pre65 caught our eye due to the close competitive racing, so we thought we would have a look around and see what we could find, We blindly made a purchase and now own a 67 Challenger basket case. after monitoring the forum as a basic user for a couple of weeks I decided to join up and crack on with the rebuild.
My hasty purchase is emerging to be probably not ideal, I think the bike has originated from the US with a GPA9 engine number and a SP1 gear box 46/67 (not kidney) and after counting the teeth and matching with an ebay purchased parts book looks like its a wide ratio.
I welcome any advice on what would be ideal gearing etc to get it ready to compete in the Greeves Challenge.
I guess I will be bombarding the Help & Advice over the coming weeks trying to find information on colours etc to get it back to original.
