needles&scary fast pwr nows

[CMAC]

01, stock carbs with vitos custom needles, stock air box with k&n and power lid stock pipes stock engine. Here is the deal. I bent one of the stock needles while jetting, so i ordered vito needles for stock carbs and at the same time i ordered the scary fast pwr nows. now the thing idles fine, is even fine through quarter throttle but when at eighth to quart throttle and going up a hill it starts bogging bad. I went up 2 and down 2 on pilots and it keeps doing the same thing. took out the SFPNs and went to stock pilot and runs fine. I dont have stock needles to see if they would work with the SFPNs. wondering anyone thinks vitos needles would have anything to do with it?

FIRST.... Um...... Throw the power now valvs away and slap yourself for buying them. They provide the same performance enhancements of a boost bottle...NOT A DAMN THING...I see you're fairly new here so I won't bash on you too hard.

 

IS the TORS removed or still connected???? That's what it sounds like. Check the air screws..Should be 1.5-2 turns out from bottom, make sure the carbs are sync'd, clean the carbs and filter, etc...Yes the Vito's needles can be the cause.

i put the sfpn on crf450, and i noticed a difference , gave me more throttle response , i never put them on a banshee , heard they dont work that well on 2 strokes

They definatly pull harder and ad a huge difference on the top end (definatly much faster becuase with out them my buddys 700 raptor is a little faster wide open and with them i walk right by him, so they do work!) and on the bottom to mid range you can feel the pull night and day. Going to order stock needles cuz they made a believer out of me no matter what anyone says. To each there own. Oh and yes the Tors is disconnected.
