The 4rt restrictors do they restrict noise or performance?

BBC yes ceefax no but thats the point of it if enough people contact them they will have to take note good to know though that you have also tried

What is considered to be the best head angle when choosing a frame, with yokes some Bultaco/Montesa for example have the steering stem at a slight angle to the fork legs while Ceriani or some Marzocchi have a parrallel setting. Ceriani yokes carry the fork legs well forward whilst others bring them back much nearer the headstock I suppose this moves the weight backwards but is it important. The more you look at this the more interesting/confusing it becomes?

Recently I contacted the BBC by email regarding featuring once again the Indoor & Outdoor World Trials results on its ceefax motorsports pages. Their reply suggested contacting ceefax direct which I did, since then nothing I shall now retry but if they were to receive another 100 or even 500 similar requests it might help. Yes I know I can look on these excellent pages but trials should feature on tv after all our Dougie Lampkin has a winning history the equal of Michael Schumacher lets give it a go

Interesting comments from Steve & HondaRS regarding fork trail (draw a line through the steering stem to the floor then a vertical line from the wheel wheel spindle centre to the floor & the distance between the two marks is the trail) this gives the steering a self centring effect That much I understand but when building a bike choosing forks/yokes etc what measurements should we be trying to acheive & would leading spindle be better than in line I am thinking about a Cub project & the merits or otherwise of Armac/Otter or modded std frames

Am building a trials cub but am unfamiliar with these engines so need help with choice of carb ignition gearing etc With the 16/17t eng. sprockets do you have to use a split link in the primary chain or are endless chains available Std frame or one of the McDonald or other types of frame kit what do you all think of these anyway
