Check out the thread https://thecabe.com/forum/threads/3hp-motorized-bike.100205/ . My plan is to remove the pull start assembly and shrouding and mount it on the outer side of the flywheel. It’s a predator 79cc 3hp from harbor freight.
Oh Yeah, I was looking at your thread. Nice project. I would lik to have it on the right side also but was just too easy the way I did it because of all the mounting holes for a base plate. You can mount your pivot shaft at the rear of the engine using the 2 mounting bolts. Also a freewheel with the flywheel retaining nut built into it would just leave the segment gear to deal with. You may want to check out this thread by a friend of mine who mounted a kicker on the right side.
Thanks StoneWoods. I made the first one by welding a bunch if 5/8'' dowels into a curved piece of metal. Then I made a blueprint and my grandson plotted it on his CAD program. Then he uploaded it onto a laser cutter he works with and cut it out real nice. It meshed a little tight so we backed off on the radius until it worked real smooth. It took about 6 tries to perfect. Nothing easy, just kept plugging away until I had a complete mechanism. I'm going to have him make a couple more so I can upgrade my older builds that are currently only pedal start. The big advantage of the kickstarter is that I don't have to incorporate a compression release.
