| Actually the DD regs say that a gearbox sprocket cover is required - though God knows why?!!
77NM/Kg/ft/lbs???? just do it up tight - but not as tight as the top sprocket cover bolt!!!!
Percieved wisdom is that alignment marks are not to be trusted - I have a pair of six foot long straight edges that I clamp either side of the rear wheel; then align the wheel so there is the same gap between the straight edges and either side of the front wheel. If that males sense; assumes the frame is straight as well. BUT I haven't bothered to use it on the 620, just used the alignemnt marks and it all seems OK to me. |
