I have a Warrior with a K&N air filter, 150 Dynojet main jet, and White Brothers E-Series exhaust with 18 discs. When I am riding it seems fine til I want to go full blast. Then from 3/4 to full throttle it just feels like it gets louder with no extra movement. It is like it loses power. Do you think I have too many discs on my exhaust?

 

try it with less disks but sounds like your needle or main needs adj,did they give you any recomended settings in any of the kits ? later

 

You need to contact White Bros tech dept & find out what the maximum number of discs they recommend using. Supertrapp suggests 20 as the upper limit on their silencer in order to supply the proper amount of back pressure to operate the valves. Possibly your silencer requires less discs to accomplish this. If so no jetting changes will do anything but add to your problems

 

Sounds to me like you ride a warrior No top end power.. Hmmm yup its a thumper!! I would check into what everyone else suggested, but I havent known ANY warriors to pull good on the top end at all.

P.S. Did you install aftermarket needle when you put on your K&N? If you didnt go get a kit, (dynojet kit, includes needle, and jets. K&N packages this plus filter as a ATV Power Kit) it helps..
