When we arrive 4 bike building this is the scene. 4 bike benches (VRs & Nickys) with an engine on each. Next 2 each bike there is a pile of boxes & tubs. Every single part, nut, screw, pop rivet, wheels, bearings, everything is there. Nothing is pre assembled. We all then pick a section & go for it. If u do one bit u do it 4 both bikes or even 4 all. If we are not sure how something goes then you check an engineering drawing or just ask Mark! Ok off 2 work. Tweet ya later.
