Ordered FMF Gnarly, Suggestions appreciated

(1/2) > >>

Danger4u2:
I ordered a FMF Gnarly pipe, e-line Kevlar pipe protector, and the Power Core Silencer. Any suggestions as far as what I should do before they get to the house? Jetting suggestions? FMF offers jetting suggestions, but I thought members might have the real world scoop on my stock '04' K5.


Thanks,

I have one! I think for the desert they are the best! I am not sure what jetting changes I made for the pipe, because I also installed a reed spacer at the same time! :D

What does the reed spacer do? I know it moves the reeds back, but what does it do physically to make more horse power. What reeds are you running?
Thanks

Timbowe:
Reed spacer shifts the torque lower down the rev range. You do lose a little of the top end, but with a 500 thats no biggie anyway. The broad spread of power certainly makes up for the top end loss. I run mine spacer with a Vforce cage and Gnarly with power core also. Only 1 size up from standard main. I also run a Irridium NGK plug and decent fuel mix [Good syn oil]. For me this is 1 sweet set up. Both my kX's have run this combo. It really makes a very good engine so much better.

KXcam22:
As I understand it, a reed spacer pulls the tips of the reeds back out of the transfer port flow which reduces turbulence (at the reed tip) and increases flow at low rpms. The increase of the intake volume could also have some effect.  Timbowe's setup is just about optimum for the KX. Mine is almost the same except I am running the Boysen dual-stage reeds. I agree, it really does make a very good engine better. Cam.
