Reverse kit for clutch bikes

[Hanginon]

If you use a 12 guage with a hot enough shell, you can get pretty good reverse speed.. otherwise, we're looking at a big CO2 cartridge as a bow thruster or possibly a mechanical oar... On the thought though, this has been rolling around in my head as well.. few ideas but the wife makes a pretty good reverse in "have to" situations.. but she ain't cheap.. lol. Perhaps like on my boat, you could get your engine to spin and fire counter clockwise and your all set!! I'll wait to see which of these ideas you all use and then get on it
