The best mod you can do to the 300ex is to put the air tube off the 350X on it. It is the rubber tube that goes from the air box to the carb.

This lets a great deal more air flow and really settles down the cold blooded nature of the quad. This is especially helpful when trying to engage the reverse when the bike is cold.

Good luck finding one of these. Best mod I've ever done. Cheapest to.

Google or Yahoo for a 300ex mod list that Mickey Dunlap published years ago.

It lists the best mods and what order to do them in so each upgrade builds on the other. It lists the approx prices to so you can budget properly. Just add for inflation.

I have a 70hp Raptor and 2 450Rs and still love to ride my 300ex. One of the reasons I've kept it so long is because I followed Mickeys list in the order he recommended. The bike just kept getting better and better.

Do yourself a favor and stop listening to your brothers friend who had a cousin that put a whatever on their bike and it broke the local police radar gun because it was so fast. If you want to beat the kid down the street who has a 400ex, get a 450R.

If you want a great 300ex look for Mickeys list.

Have a great New Years, I'm going to Glamis.
