I questioned the PO when I bought the bike about receipts and he never kept them as it was 13 years ago. When I picked it up he had all the old parts ( Pistons, Cams and Throttle Body ) for me to bring home but as I had a 1000km ride home I didn't wan't them. I rang his dealer to try and get the information but they replaced there computer system a few years back and said they have no records available from 2014 when the work was done. I do have the Dyno sheets which list compression lifted to 10.1, Andrews 54 cams, 58mm throttle body and Fulsac exhaust. I rang the PO again the other day and he said he had the lifters and cam bearings replaced when the work was done because of the known problems with the engine. The bike also has the Baker 1.5L bigger sump.
