Wondering if worth adding K@N air filter and FMF exhaust on 2004 TRX350 Rancher. Think any valid power gains will be acheived, or am I smoking crack for trying to hop up a utlility ATV? I like the bike, want more power....

 

hey, nothings wrong with hoping up your utility quad..lol...but I dont think you'll notice a diffrience. if you want a racing power change, Id sell the quad and buy a 400ex, or the new 450

 

Thanks, I thought maybe any noticeable power gains from these mods might be null and void. Wished I'd asked first before ordering....

 

haha....yea..they like to do that...I almost bought the tornado vent thingie for my old truck...then I thought..." that wont fix the oil and rich gas burning problem...chevys...."

 

Molokai, anytime you will notice a pretty big improvement compared to stock, if jetted correctly with thouse mods.

 

Good topic...jetting....seen the kits....wondering what they heck they are and do...
Apologize for the lack of intelligence...

 

Dont worry about the kits. I would go to a dealer, ask them what size you need(cheep mod its like a $4 thing). Or FMF could probally tell you. Its a really simple thing to do. You just need to get to the carberator and replace the jet.

You may want to bring it to a dealer, but my guess is they would charge like $20 for a 10 minute job

 

Is it important to jet after slapping on a pipe and air filter? If left alone, will it be ok?

 

You need to jet. You will run lean.

 

Called the Maui Honda dealership asking if I need to jet after installing the filter and pipe. Of course they said try it first to see if it sputters...(Hmmm....professionalism at it's best!) After, I emailed FMF to check, waiting for their response now...

(The dealer even said to jet will cost me $120.00 for parts and labor...ahhhh...it's good to live in the middle of the pacific ocean...so many options...yeah right...)
