Probably around 67-68 mph. Top speed doesn't mean squat unless you are desert racing or something along those lines.

So, mine should top out about the same? I have a Pro Circuit slip-on and a K&N filter with the jetting corrected. I agree about top speed not being important, at least not to me.

Believe me i have been riding quads for about 13 years now and i know that top speed really doesnt mean a whole lot, but its just one of those things some people are interested in, my buddy is thinking about buying a used 400EX with those mods and i was just finding some stuff out for him. Anyways, thanx for the reply guys i appreciate it.

That's probably about the average for all piped 400ex's depending on your tire size. If you do a search there is probably a ton of info on this.

It all depends on what sprockets you run. When im raceing Roundtrack or Drags i run a 13 front and 44 back. And if i just fill like playing around i like to run a 16 front and a 42 back. But have not glue how fast im going i know it makes my eyes water [img]i/expressions/face-icon-small-happy.gif[/img][img]i/expressions/face-icon-small-mad.gif[/img][img]i/expressions/face-icon-small-shocked.gif[/img][img]i/expressions/face-icon-small-tongue.gif[/img]

Thanks for the replies. I just wanted a general idea. Top speed doesn't matter to me at all. But for some reason, people always ask you how fast something will run on top end. It doesn't matter if it's an ATV, motorcycle or truck.
