One of my Cxs stopped charging properly and was hard to start.At first I thought it was possibly a Stator problem however I had noticed that the old Main fuse and holder were warm to the touch.
I replaced them with a cheap in-line 30mm type car fuse holder so I could keep all the same style fuses with me

This cured the bad starting and bad charging and the bike some 2 years on has never had this problem again so far

Some users have opted for the,"Blade" type units,
