[QUOTE=LowPSI;18960587]You're welcome Brewtus. The TS scene in Spain is big. I like to see the tricked out TS bikes but I also like to see them ridden in as original condition as possible .
When the NATC TS class was created we submitted a list of rules to keep the mods under control. They decided to keep the rules at air cooled, twin shocks, drum brakes. As the class gets more popular they may have to add some rules. Its easy enough to do.
Basic bike prep is not cheating. Just because a bike is old doesn't mean it has to run like crap. Correct timing, fresh exhaust packing, proper carburation should be the norm, but I see guys show up with bikes that ran worse than they did 35 years ago.
The main thing is to keep it fun and bring out those old bikes and use them to bring in new riders.[/
Things have got completely out of control in regard to Spanish TS trials, with highly modified Spanish bikes costing £8-10k to build being ridden in classes originally intended for authentic bikes manufactured before certain cut off dates. This means those who cant afford on of the tricked up bikes find it difficult to compete, as the modified ones are so much better.
Its very sensible deciding to use rules requiring only air-cooled motors, drum brakes, 2x rear shocks, which means its possible to build a reasonably able TS bike from an old air-cooled mono, rather than spending 2/3 times as much on altering an original bike along the same lines as those in Spain.
