I am in the middle of restoring a 64 Dot with 37a square barrel motor for classic pre65 trials competion here in Australia,but it is hard to get any info over here. I need to known the best set up for trials gearing,primary rato ,secondary ratio front rear sprockets etc. ,gearbox ratios etc,,,it looks like this motor has had the gearing changed in past maybe to used as a scrambler so i need to known the the best set up for trials and where to get sprockets gears etc. What sort of 1st gear ratio should be aiming at. Thanks in Advance Peter
