i recently bought a full exhaust for my warrior ... a yoshi full exhaust and yesterday i took it out to the test it .. and my head pipe was extremely red after LIKE 2 HOURS or so of ride ... i live in texas so the heat was really bad yesterday.... is this normal?... ive taken it out before but it never got this red...

 

did you rejet?, it could be a lean condition

 

yes i jetted it to stage 2 with an open box and k&n filter

 

seems like it may still be a little rich, with a full pipe u gotta reject, but when you run without a lid you gotta run it even fatter.

 

is this something i should be concerned about... and what shoul i do..?i was also thinking of selling it and buying me a honda trx450r or yamaha 660r which is better or any other ones i should get?... by the way i dropped a tooth in the front sprocket..
