The only problem I hear of, of the yfz450's is the oil thing lol. The only problem I've had, which isn't a "problem", is that it's a little boggy in the very low rpms. But all you need is a little common sense. USE THE CLUTCH. Since I'm more used to cars and such, I tend to use the throttle more than the clutch, which sometimes makes me kill it on hill climbs. To solve that problem, I just changed a sprocket. Now I can do wheelies without effort, and I can even use third as a good gear for climbing! The gearing is made for racing not hill climbing. Theres a balance to every bike. The 450rs tend to have more low end torque than the others though. I love my yfz450v, but I would also buy the 450rs, or the ltrs. Fuck the others. They costs way, way too much. I suggest that if your and idiot, or a virgin to powersprots, buy the $12,000 bikes. I'd rather buy a cheaper bike with the same potential.
06 yfz 450v
gytr jet kit
gytr filter and adapter
gytr header
Dr.d slip on
ngk plug
13t front sprocket.
Dg nerf bars
air box lid removed
by the way, the gytr header and dr.d slip on are the only used Items on my quad, and I've only spent $470. I got the bike for $5,050 two years ago brand new. It's not that expensive to make a blistering fast quad, if your smart about what you buy. Just look around when buying. Now I run with the $12,000 quads.
And for those who says who say the yfz 450s suck, look up how many years in a row they got best quad. ;)
