UPDATE. Thanks for the replies. The ilco x248 blank is listed on some sites as compatible, but having one alongside a factory original, there is a very slight difference. I was able to file down the cut key a little and it now works in the ignition as well as gas cap. the x248 key blank is not commomly available.
mwakey- this bike was used and I did not have the key code for it so I could not just order a precut copy from the dealer.
