I just got my first 4-stroke dirtbike, 1999 WR400 and love it. I just had a few questions, the headers seems to get extremely hot while riding to the point where it is glowing at the front, i was wondering if thats just how 4-strokes are or if my bike is running too lean. Also, my killswitch is placed directly in the middle on my handlebars, which seems a little dangerous, when i want to kill my motor is it okay to just grab the compression lever? And one more thing, my bike does not want to pressure start, i was wondering if i could still pressure start it if i held the compression lever in a little bit? Thanks.
