2008 YFZ top end fuel/power loss?!?!
I have a 2008 yfz 450, i ride it at little saharra sand dunes alot and when i climb a long hill it feels as if it looses fuel and all power on the top end after about five seconds of climbing, this is ODD it feels like it looses power completly. its rapped up in third almost being able to get forth so i got plenty pf power and wheel spin to keep it going then it does this and i have to shift to second just to make it. any ideas? i've messed with jetting going back to stock jetting all the way to 170 jetting, its got a T6 pipe and ron woods intake.
