hi!i was looking online and found the vespatronic ignition with 2 different prices and titles, the cheaper one was titled EVERGREENVESPATRONIC

and the xpensive one is simply vespatronic on SIP and S&S.

also the expensive one has no flywheel extractor and the flywheel colour is grey.
are there any significant differences between the two?cheers!
