Am considering a Dave Patrick Extra and powering w/ a Moki 2.1. I do not have any prior experience w/ Mokis or any other 2 stroke this size. Is there a unique setup from what I might have done with my OS .46, for example? I have seen mention of a special backplate for the Moki and something about an ignition switch with a separate power supply. Can anyone walk me thru (with detail) how this unit should be set up? Thanks.
