What he said /\/\/\ The kits are not going to be that helpful, they are not like a China girl or 49cc 4 stroke kit where you get literally everything you need to make the bike go down the street under motor power. They will spend your money to show you what the parts look like that you need, then go buy those parts elsewhere like AGK etc. that are up to the task and fabricate the rest. The best way to look at installing a Predator motor on a bicycle is that you need to be fluent in every aspect of motor installs on bikes and then some to make one actually work properly.
