alright heres some numbers....

our engine: 1,598 cc
honda 450r kickstart engine: 450 cc
pull start lawn mower: 160 cc

Our engine is more than 3 times bigger than the kick start engine of 450cc. From personal experience, that can even be a bitch to kick start. Not only that but kick starting is easier than pull starting because your force is going with gravity when u kick start as opposed to against in pull start. Plus our engine is almost 10 times larger than a pull start motor of a lawn mower. In other words, you better have a few weight lifting buddies to help you every time you want to start it
