I need to replace the hiss as I've lost my keys, I've been looking at used systems for sell but can't find a ecu with matching part numbers but their from the same year bike, will this be a problem? Thanks

 

I personally think this would not be a great problem, since bikes from the same year make and model all have the same components.
You might want to ask if you can return it if it doesn't work.
And definitely ask for confirmation of the seller if the parts are compatible.

 

Just make sure the parts are from a European bike, the US ones did not have the HISS system on them.

 

I've picked up a complete hiss system today with ecu key receiver and locks so I'll give them a try tomorrow and keep you posted

 

All sorted,bikes running now. Thanks for your replies

 

Fantastic, thanks for letting us know.
