2002 wr bog!!!!!

4 posts in this topic

I have a bog(actually it kills the bike) from idle when I stab the throttle. If I give it just a little rev before I stab it I have no problems. I just changed the pilot jet to a 38 and dropped the main one step from stock(cant remember what it is off the top of my head) with no change. I have done the BK mod, and the blue and gray wire mods. Im new to 4-strokes and not sure how to get rid of my problem. Other than this the bike is amazing. I ride 4500 to 8000 feet. HELP PLEASE IM desperate

your ultimate answer is to lean out the pilot circuit to the CORRECT level.

a quick answer would be to lower the PAJ to a 60. if you read a 200 thread write up from april 20th called jetting Qs you'll see that i talk of a low speed throttle lag and talk of the "first 4mm of throttle where nothing happens".

these bikes like to be very rich or to be correct. if you're slightly rich they bog.
