i now have the coolant temp warning light on and the bike wont start its flashing er1 and er2. this message carries on after yesterdays 1 about incorrect speedo reading. help. its under warranty but is it up to me to get it to the shop because i obviously cant ride it.

er 1 & er 2 - ECU internal malfunction

engine cannot be started with these error codes on dash

try to clean up connectors on display unit and ECU ... most likely they have corroded due water ingress

this all makes sense, last weekend went out got soaked then got home and never went out untill this weekend, then all my problems started. This is a little worrying to think a lot of rain can do this,what am i meant to do to prevent it happening again.

cover your bike with something when raining outside ... use wd-40 or perhaps vaseline/petroleum gel on all contact surfaces of exposed electrical equipment, connectors, etc to prevent corrosion and water penetration ...

my bike isnt left outside i just went out in the rain for a couple of hours, its been garaged ever since.

I ride all year round in some bad weather, after having electrical problems on my VFR due to corrosion of contacts, it's worth me going over the loom with some petroleum jelly waterproofing all electrical plugs and contacts.

Dabbing some grease on external bolt heads does no harm either. I don't think it's a particular flaw of any bike but water is a ****** and can randomly cause all sorts of grief.
