I was going to ask a similar question – can I get at the area in question to check the wiring without removing the tank??

The images are great at showing the point where the cables rub the frame, but I can't figure out where on the bike I need to actually look for this

With over 5000 on by Ten now I think it's about time I took a look

Oh… and just out of interest, have you encountered many other problems during those 51,000 miles?? Makes my 5000 look a little weedy
