I can't seem to see the part via your link Debs & I couldn't find any thing on the part number you listed. On a OEM part supplier it says the part is 5YK�8255P�00, if it is the bit that sits under the ignition barrel. Its listed at $559 Aus Dollars. Maybe the part on your bike was a quick fix to get it running as to sell it on? Perhaps the whole ignition assembly has been changed?

Sorry for a silly suggestion as I don't know you situation but is it possible to contact where you got the bike from? Good luck.
