it that a 704R engine? did you use a clutch?
yes!
would you be able to make it so it could detach itself from the motor and then you could use a killswitch and turn it off to go manual?
Yes! If I'm getting what your saying!
so it hit you in the butt too make you go faster lol

Dude you could make a mini chopper and put that 4 stroke engine on it!!
haha that would be gnarly
Yep! lol!
How do you engage, disengage it? It can't be pushing the bike the whole time, can it?
Yes it can be pushing the bike the whole time.
Most weed whackers use a centripetal clutch so when it is idling, it is still or free moving. Only when the RPMs increase does the clutch engage. I wonder how it would do with a 45cc?
It whould do&nbsp; relly good with 45cc!
Cool
Thanks!
Awsome!!! But wheres the clutch?
<p> It does not need a clutch but it has one its pretty much the thing on the tire.</p>
That's cool man :)
