Route between the fork ears, behind the headlight, and down the frame tube between #3 and #4 exhaust headers. Zip tie the cable to the frame tube, one tie just above the headers and one down low just before the cable makes the bend back towards the clutch. Sorry no pics but it's pretty simple.
If you're using lowrise bars(stock bars have a 5" rise,low bars have 2" rise) or even drag bars or clubmans then there will be a lot of extra clutch cable to deal with. Motion Pro sells a -3" clutch cable that fits great with lower than stock bars.
