lol whooo!
i agree it is the rider...99% of it...
the guy on the 450r i ran against wasn't as good as i am...and i have ran against tons of other 450 and just the same...
now i love the 400 set up over everything else i have ridden...that is why i put in the 500 motor because i like that frame...now i can trail ride at 90+ and drag...problem solved....
Ughhh.
These debates always come up. Here's my view on things.
The 400ex is a great handling, nimble, timid trail quad. The reason people build them up is because of their chassis. Like I said, in stock form, the engine is very timid and mellow. That being said, you can turn them into monster's.
A WELL-BUILT 440 or 460 stroker can really run. But, I view it as, if your goal is to build a high-powered race quad, and piped and jetted 450 of any brand is the equivelance of a built 400ex. So, if you plan on racing, I would still stay the 450 route. Most pro's race bikes are pushing 60-65hp. Im sorry, but you're not going to get that out of a 400ex without nitrous.
I view the 400ex as a fun, nimble weekend warrior trail quad. While, being a great amatuer MX quad. You can get them to handle really good, but not go quite as fast, unless your comparing them to a piped 450.
Right now, I am plenty satisfied. I own two of my favorite quads:D The only think I would ditch the 400ex for is a raptor 700, but it's not like something Im desperate to do.

Ok.......bottom line, I'm not going to say what you need if it's for a drag race. MX racing is different, you'll need a competitive engine at least (426cc). With porting, FCR carb, and a good exhaust. Then you need +2 a-arms with good suspension and a rear revalve and a GT thunder or Elka link. Few other odds & ends and you'll have a LTR killer.
