I own a 1998 warrior and i have installed a white brothers R-4 slip-on, a FMF powerbomb headpipe, K&N air filter, wiesco piston, .450 lift cam, and a 14 tooth sprocket. I live in alabama on high elevation. I still have'nt figured out what jet is going to make my quad perform at its best though. Right ow i have a 160 main jet. The air box lid is still on. Should i change the jetting or should i get a new carbrueter?if i should change the jetting what should i change it to?thanx

 

Is it running rich or lean or what? I don't think you need a new carb unless you were to go big bore..


btw, did the FMF headpipe fit right onto the WB R4? or did you have to mod it?

 

well its running lean. what size main jet should i use if i take the air box lid to?

 

oh yea the FMF powerbomb fit right on to the white bros R-4 with no problem at all.

 

Hey this is Warrior68man I'm at kawasakimans house...if your using a 160 main jet right now and want to take the lid off...try a 170 or 175. You could always try...then go from there.
