suppertrapp exhaust, 2 stage uni filter, no aire box lid, and jetted to match. thats the best bolt on.

Thanks alot. Would it be advantageous to put a 38mm mikuni carb on too or not?

Everyone seems to like the 400EX carb with the accel. pump along with any kind of exhaust upgrade.

I have the 400EX carb and a TRX450R silencer and will post the results when I get it all dialed in....

Does the 400ex carb fit the stock air box and intake boots or will I have to make a few modifications?
Thanks

I believe it is a direct bolt on, I have both carbs and if I get a chance I'll measure them later today....

I was wondering what advantages there are to the accel pump on the 400ex carb. Does it just simply run better with better throttle response? I'm not too familiar with this set up and its function...

Anytime you can change a carb to a carb with an accel pump, than it is a good mod. You have a more instant throttle response than with a non accel pump carb. Hopefull on the 400ex there is an adjustment for the accel pump so you don't flood the carb though.
