went on some major trail rides a few weeks ago! the last day of riding my 220 started fouling plugs badly, just barly got back to the truck after replacing 4 plugs one new and three retreads© got the bike home to fined air filter totaly plugged big time? and my air screw out of ajustment 1 1/2 out in steed 2 1/4© I spoke with Mr© fredette and I ask him if the air filter thing might of caused me to go rich? he said most likey not© he suggested to go one size smaller on the pilot jet because I told him I was riding clean up with a couple young one's and really dogged it on the trails© so I cleaned up the carb yesterday and found the air screw in to far? I still pulled a part the carb and cleaned her up with brake clean, she was very clean in side any way! found my jetting was, pilot was 45, main is 155© put her back together and put a new plug in and air filter, set air screw at 2 1/4© did a full speed run then shut it off and checked the plug was perfect? went the board and did a search on jetting for a kdx and found stock was 45/145© so I'm a little fat on my main?
SO HERE'S THE 94 DOLLAR QUESTION? DID THE FILTER & AIR AJUSTMENT CAUSE MY FOULING PROBLEM? OR SHOULD i STILL LEAN OUT MY PILOT? I'm defently buying the jets! and will try the nexted size smaller pilot like mr fredette sugested© just would like a second opion!!!!!!!!!!!!!!!!!!!!!!:think
