hey guys i just finished some modifications on my 87 warrior 350. first i put a unifoam filter kit on it. then a few weeks later i put a white brothers pipe on and a 150 jet. before the pipe and the jet it ran fine. after adding the pipe and jet it runs like a bat out of hell but sputters when it is revved up in 6th gear. any ideas?

 

airbox lid on or off?

 

the lid is still on

 

put a 147.5 main in it

 

ok. i bought a 147.5 when i bought the 150 because i have heard of people using both with similar setups to mine. i will try the 147.5 and see what happens.
