Got my '04 XRL, 85 miles so far, and am starting the un-cork. Took out the carb last night, a [@#$%&!] as all carbs seem to be. Am going to put the (mildly sized) jets in, and noticed a stop on one of the screws beneath the throat. Is this the air screw? Why is it stoppered? Pulled the smog stuff off, tonight I'll make the block plates. Snorkles out, Unifilter in, tires mounted, and the guys want to go to Walker Valley to see if I still know how to ride (that's for them). The trail will tell, eh? Great forum, got some great input already during my "lurker" period. THANKS!
