im workin on building up a XC quad, and i have no clue where to start...anyone help?

Tires, skid plates, suspension, bars, nerf bars, power upgrades such as exhaust, jetting, airfilter etc...

These are just to name a few. There are many things you can change and it all depends on how far you willing to go and how much you want to spend. Do some searching in the "My Assistant" at the top of the page. You'll find pages and pages of info on this site about upgrades to your quad.

By the way.....welcome to the site!

On an xc bike you mostly want RELIABILITY! So A hi-comp piston intake cam and a 39mm fcr kehin carb is all id do to the motor. Unless you want a bigbore. Talk to anthony at Triumph motor sports Click here for link Or Curtis Sparks Racing click here for link

Work on Alot of protection Like ProArmor Click here for link And mostly aim toward the A-arms and motor protection. And swing arm also.

And Tires and misc. things like steering stabilizers. Go to rocky moutain atv Click here for link

shocks are where its at you need a good handleing quad for xc and a good stabilizer like a denton

have fun and good luck

make sure you have good protection for the quad! i have always used ac,pro armor and um and really happy with all three.
tire wise i like the maxxis razer two, hook up really good and last awhile.
get ahold of me i can get you set-up good, i also have a set of razer two tire front and rear to save a little money, but tires only have one race on them. got them for trade on some others parts.
