I just picked up a 02 400ex for my gf, the night i rode it it seemed really cold blooded, not too bad i didnt waste much time with it the price was right so i picked it up
At first it wouldnt idle much on its own for nothing, so i took the carb out, both jets and cleaned them, messed with the idle screw. I finally can get it to idle when its warmed up of course. but at about 1/4 throttle it runs but not consistent. It will go and then stutter, go again. Seems as if its backfiring through the intake. I changed the plug, and did the carb. I was wondering what are the signs of valves needing adjusting? I was going to do it today. I ordered 150/40 jets it has a motoworks slip on, so i figured it wouldnt hurt at all. When it runs passed 1/4 throttle im surprised how much power it seems to have, im coming from a 700 raptor, so im all new to carbs and everything else
If you guys have any ideas how i can get this up and running please let me know thanx
