Front wheel drive makes sense in ICE cars that have front engine weight bias, otherwise I don't see the point of it from a traction point of view. Hitting the gas makes you plow. Rear wheel settings gives you the option to steer with the throttle.
Wish I found your video before lol. Just rebuilt my ‘03yz450 and it had me dying while trying to turn it on. The kickstart bounce back up hit my shin and got swollen🤣 Thats what happens when you got a kickstart bike #BeAMan
The hardest part is re-installing the hold down brackets. I used a retrieval magnet once I got it flipped up (I just dropped mine in the opposite way you do it, and then flip it up with my finger, piece of cake) to hold it in place. You can move it around to line the hole up and you don't have to worry about it falling back down. I don't have a magnetic socket, so I wrapped a piece of my parts receipt around the bolt head and stuffed it in the socket- holds it perfectly. Once I figured that out, putting the hold down brackets in takes about 20 seconds.
