Hi:
I have a jetting question.
I have a 2004 Yamaha WR450 (Canadian version) with a White Brother E-series pipe. I run at sea level to 2000 feet, 40 to 80 degrees, and I ride tight trails and some open sections. I uped the stock main jet from 160 to 165 and turned the pilot jet out 2 turns. Still, from 1/4 to 3/4 throttle when held at a constant speed she chokes, burbbles, does not breath well. The plug is a little white so shees still lean. I have ordered a JD jetting kit last week.
Is this a good idea, any suggestion on jet, clip position...
Thanks
