i just bought a new 05 yfz 450 and was wondering what are some of the first and basic things i should put on it to make it perform better can anyone help me out???? how are these quads and what have you done to your???? thanks for the help

 

1) Dr.D Slip-On Exhaust (won the Dirtwheels shootout)
2) Pro-Design Pro-Flow Kit ( Your choice of a UNI or K&N Air-Filter)
3)GYT-R Jet Kit
Nice boost in power [img]i/expressions/face-icon-small-smile.gif[/img]

 

cam mod

 

and retard the exhaust cam 1 tooth

 

You could get a Dr.D pipe from HERE for only $230 w/ S/A & w/o Quiet core...

 

can someone explain why you would need to reatrd the exhuast cam 1 tooth and would the slip on give me as much power as getting the whole system does anyone have a slip on if so how does it compare to one with a new head also?? i am trying to make suer i put my money where i am going to get the best results

 

Because the YFZ's stock head pipe is very well designed, and most copany's dont even make one because of that fact. The Dr.D slip on gives the YFZ a nice deep bark, and free's up the exhaust flow which gives you more power. Also, i dont know exactly why, im sure someone on here can tell you why, but retarding the exhaust cam one tooth does give you quite a powerboost, and some sights have step-by-step instructions on how to do it.
1) Dr-D Slip-on 230$
2)Pro-Flow with K&N or UNI ( 90$ - 120$ )
3)GYT-R Jet Kit ( 65$)
4)Cam Mod

Very good boost in power all across the board. this is the best way to spend your money on this quad. Plus, you need to do all this befor you can start modding the engine in the future, like bore kits, port and polish and so fourth.

 

retarding the cam puts the motor like the dirtbike motor and it does give you more power

 

when u retard the cam(exaust correct???) where does it give u the power to...racing mx..how will it help..or not worth the time

 

Gives most on the top-end.
Some bottom and mid, but not much there.

Also, I would avoid the jet kit, and just buy the necessary jets/needle individually. You'll save yourself some money, and not have several jets that would be of no use to you.

Also, I agree, you probably won't see much (if any) benefit from an aftermarket header. Spend that 150-250 bucks on an aftermarket cam, intake, or suspension components (if necessary).
