It's a very easy engine to do cam timing wise, but if unsure better to spend a bit to ensure no probs.
But basically you line up the TDC by the LUG, nearest the "V" groove in bottom pulley being in line with the pointer and the cams pointers facing as you look at them the left hand(exhaust) pointer at 3 o'clock, the right hand(inlet) at 9 o'clock, these will face each other and be in line with the seam between head and rocker cover.
Whilst in this position the scribe mark on the outer edge of the dizzy body with cap/sheild removed must be bang in the centre of the rotor arms path.
Phase sensor gap is 0.2mm to 0.3mm and the crank sensor is 0.6mm to 1.0mm.
