I was wondering if anyone knew if the D&D powerbreathers were any good. I was thinking about adding it to my 98ZL500 it has twin pipes now. Just wondering if it was worth it? Or if it would help any? Thanks.
My brother-in law has a 98 zl500 and put a powerbreather on but not sure how much difference it made as he also added UFO's ,Vforce2 reeds and a clutch kit. I can tell you that all together it made a big difference.
Also we gutted the airbox one day (with the powerbreather) big increase in pull .
I have UFOs and twins pipes thats about it. Looking toward the powerbreather to help it breathe better. Does your brother in-laws run rich with the UFOs? Mine runs rich a lot in the midrange. Just wondering if you knew if he changed his needle jet or jet needle when he added the UFOs? Thanks for the help.
all the cat guys i ride with have the powerbreather and it does make a huge difference when used along with v-force reeds and pipes. They dont seem to breath very well with the stock airbox, my uncle put one on his zrt along with reeds and a b&b can and it really woke it up.
WE have D.D. power breather on a 98`zl,scents 3 winters ,jetting with the D.D.
super single,grass drag set up for trailing, lite weight camoplast track(8lbs under stock)
ets rear coupling kit .This sled aslo has v-vorce delt 2`s and a wahl brother hub and disc set up.
The gas mpg 12-14 now the jetting is up to 420`s (390`s) with pipe only.The clucthing
is is orange primary,pink secondary,dda dylton helix and if i recall correctly it swing`s
52- 52.5 grams.This makes it wake up and stand tall (5500-5600)engage you need
strong clucthing with these engine to make the run.You should change your carb to engine boots if you all ready haven`t,for they crack and end up sucking air and burning down.
these set up will run with or ahead of the new 600`s and most of last years 7`s except
for 700 doo`s.You will out run a clutched viper right trougth top end.
