Or, more correctly, Bloody Terry Shepherd NS400 to 500cc conversions... Just had a call from the shop about, oh I don't know, the 20th problem they've had.... The latest one for TS's "bolt-on" kit is that, now the engine is all together, and now that the pistons have bee machined to fit, and now that the exhausts finally fit properly..... The extra height and width of the cylinders has pushed the carbs up too high so they foul on the frame. Only available solution appears to be hacking lumps from the frame to fit the carbs in... How the aibox and tank will then fit is, of course, not known yet.... So the prospect of the NS appearing in time for Saturday is looking bleak to say the least.. :( Dave
