Hard starting cold or hot

[Fazerjon]

Quick update and a bit of info that may be useful if anyone else has these symptoms. The switch started playing up again last week so I started looking for a replacement. Looking at roughly £500 for a new one!!! I rang my local bike shop for a price and he said Yamaha no longer make them and his supplier cant get them anymore. He did say however, they can be stripped down and cleaned up. So I did exactly that. Bit fiddly drilling out the shear bolts that bolt the switch to the yoke, then there’s 2 more to drill out that bolt the barrel onto the switch. Once thats done you can separate the two and get to the contacts to clean them. I used contact cleaner with a light rub using a green scotch pad then put it all back together. Finally some graphite grease in the barrel and she now starts on the button every time  :thumbup
Hope this helps.
