phizzle

Hi, My problem is that my 2000 r6 wont start all the time, when it does it dies on low revs, had the RAC out and he found a warn earth wire, he bolted it on and it started and ran on tick over perfectly. I went to ride it home and leant it upright and it cut out again and wouldnt start again. The loose wire may have been a red herring. I checked the side stand switch but no problem there has any one got any ideas?
