lol yeah

 

Put it in the back of a 100mph pickup.

 

You could change to taller gears. I dont think a stocke 400EX would pull gears that tall. Why would you want to?

If you want it to go about 100mph with the stock engine you would have to change the front sproket to a 17 and the rear to about a 25 to 30 maybe and then find a hill. With this gearing you will mostlikey have to have someone push the 400 to get it started and it still might not run that fast on flat ground with the stock engine.

 

get every engine mod out there then change the gearing, then ride

 

i don't think any STOCK quad has the ability to pull gears tall enough to get you into the 100+ mph range
