this is the best yfz video on youtube hands down. any advic on whether to get the 2009 or the 2010 version and would you prefer the r or the x

@riders634

all depends what you ride! Track go R trails go X

i have a 2010 yfz-x with the same pipe but slip-on it kinda bogs in lower rpm's and doesn't completely open up on top. Do you think i just need a fuel controller? looking at the hmf controller and airbox lid removed maybe?

@Tmanmauli2255

Mine did this too, you will need fuel controller for sure. shoot me an email bvcracing@gmail.com and i can get you a deal on one! also, you will want to super-glue your tip over sensor.. mine would glitch out all the time and make my quad bog on hard landings like in the video. and, i also run with the airbox lid most of the time... actually was a tad more responsive. I am going to test running the lid with small cut outs or vents.

I run a wiseco controller, but HMF does the same thing... id get controller first and try both. Some days i run lid, some days i dont... shoot me an email bvcracing@gmail.com and ill get you a deal on the controller

Love this video! Ordered the HMF performance series carbonfiber exhaust for my 450X BB after watching this video.

[pcountyredneck]

Would u recomend this for for gncc. And if not what exhaust would be the best for it?

[vizilla413]

can we order those graphics off your website? i love those. and nice exhaust by the way thats what im putting on my quad. it performs best in the woods since it adds more power to low and mid rather than what u tested which was pretty much high. but still nice vid.

Where is this track open to the public

[tippmann2424]

this track is a death track, screw up once you headed for a tree

[ThePaintball53]

really nice dirt

[stinkyfarts445]

Have you heard the R with the rs-2 yet? thats what I want to buy. I plan on getting the fci intake system and a fuel programmer myself. How do yo think she will run? Is it gonna be a huge difference over stock or not really?
