OK I asked this in two other categories (utility and mods) and received no reply so this is my last try any input would be great...

I'm some what new to the ATV seen, I had a XR400 for a bit but realized I don't have time for two bikes (also have a CBR929RR) and traded the XR for a Kodiak 450. So far I have a 150 miles on it and a ton of fun, I was wondering what performance mods I can make to this quad??? The only pipe I seen for it is the HMF pipe, are they any good?

I know its a utility quad but I want to squeak as much power out of the engine as possible and please no "you should have gotten a Rincon, Grizzly or Prairie." I went for the 450 because its perfect for what I'll use it for but come on why leave it stock? [img]i/expressions/face-icon-small-smile.gif[/img]

One more thing what is involved with the first service? Is it something I can do or should I bring it to the shop, dealer told me it would cost about $100 but never told me what they actually do.

Thanks for the info...
