Worse than terrible handling would be not being able to stop with those Sturmey Archer front brakes, at least the rear wheel has a proper moped type hub. You may want to add some cross cutting to the brake shoes to improve their braking capacity, even if you just have the kitted engine and do not up the gearing.
You had better make sure the tyres are in top shape.
Do you know of Brian Alpin's "Alpin of Bristol" shop yet... he would be an excellent resource for NOS bits as well as vast expertise in everything Raleigh.
