What Mods?

[hondaman440ex]

We are looking into upgrading my brothers quad. He is old enough to handle the power upgrades now. And we were wondering what upgrades we can do to it without spending a ton of money. We were thinking of a K&N air filter with a prefilter, removing air box cover, and an exuast. Which exuasts are good to get that are not to expensive? And will a slip on be alright or should we get a full exuast? And what would you recommend getting a new CDI or cutting the pink wire?

EXHAUST, AIRBOX LID, CUT THE PINK WIRE... THE USUAL. IT DEPENDS ON THE YEAR FOR A REV BOX. THEY AREN'T READILY AVAILABLE FOR THE 06-07 YET. BIG GUN SEEMS TO BE A GOOD INEXPENSIVE CHOICE FOR THE TRX90 (ABOUT $220 FULL SYSTEM)

JETTING CAN BE TRICKY ON THESE SMALL QUADS. I'VE HAD TO SEARCH FOR JETS FOR OTHER MINIS LIKE THE CRF 80 AND 100 TO GET WHAT I NEEDED.

GOOD LUCK.
