Hello! I have a 1986 XT350. I believe the jetting may be stock. I have bored the engine out 1.5mm over and I have installed a Uni foam filter. Except what I had mentioned, the bike is stock; no drilled air box nor grounded header welds. I would like to inlarge my jets in hope for a nice, healthy running engine, however I am not sure what size I should go up to, nor where to get them. Also, I would like to up the pilot jet to help to get it started- unless this would create more off throttle bog; but I can not find out where to purchase the poilet jets either. Summary of my questions: 1) What recommended jetting should I try? 2) Where should I purchase them? 3) Should I jet it a little rich- better too rich than too lean, correct? 4) Do I have to rejet BOTH carbs? 5) Would an uped pilot jet create greater bogging off the throttle? 6) Is there any other information you would like to add that you feel that would help me? Other helpful information: I live in North-Eastern Ohio Elevation is 1160 feet above sea level Roughly adverage 70% humidity I would not like to purchase a jet kit but I would like to purchase individual jets. Thank You!!! Colton W.
