Hey I was just wondering what are some of the easy and for the most part cheap ways to make a 300ex even just little by little faster because all my friends have bigger faster quads but mine doesnt keep up and on a tight budget I need some help on some ways to make it faster in a cheap manner.

Thanks everyone

 

hey man one cheap setup is to buy the k and n airfilter with a pre charger and put a jet kit in it i have i the same setup in mine it on costed around 150 bucks

 

There is a fair bit of hop up potential in this engine! UNI air filter (K&N will pass dirt!), vent the aibox lid, aftermarket muffler...and of course a rejet.

The 300 desperately needs a bigger header. When I bought an FMF PowerCore 4 muffler, it came with a header.

 

how do u vent the air box please let me know

 

ok i have a 1999 300ex and it was bore 80 over i was riding in the field and it locked up i took it to a shop and they told me i cracked the cylinder walls do u thing the motor could still be used

 

If you didn't eject shrapnell into the crank case and cause other damage. I think you'll be fine with a new jug and a top end rebuild.

 

cool thnks for the help

 

cheap way to vent the airbox is drill holes in it.. but that also lets lots of particles in.. if you do this i suggest an outerwear on your filter.. they also make aftermarket air box lids with holes in the top of the lid that have foam inserts
