YFZ450R Dyno run with Barker exhaust
« on: February 27, 2009, 11:09:43 AM »
the stock quad pulled 40 HP (with airbox lid ON and exhaust plug IN)
after the Barker Exhaust was on (airbox lid OFF) it pulled 45 HP and 30 FT LBs of tq

we put in the quiet core and it sounds GREAT!
only lost 1/2 of a horse and just over 1 ft lb of tq
(quiet core 44.5 HP 28.? ft lb tq)
here is a video of the run from my VholdR Helmet cam
(that is Tim Barker on the quad)

http://www.vholdr.com/node/15238

it sounds REAL good in person, kinda hard to hear in the video
(very similar to the 700 with barker duals)

comments?

I have other video.. just takes some time

PS.
I should note that we DID install a PC5
and the fuel mix was DAMN close
only took minor adjustments to make it perfect

With professional motor work and Barker, only 5 hp? Or was that just by adding pipe. (i hope)

Nice ride nonetheless. I would like to try out the FI 450r.

Hefe, any way you could send that map to me? I've got a buddy that just ordered Sparks exhaust and a PC5.


If so Please send to Predy08@yahoo.com

In the thread where you had the pics, you said you sent it away for work to be done. Sorry I misunderstood.   :thumbs:
