Hi guys, my '99 SRX 600 has been fouling plugs during warm up, i always let it warm up for about 5 mins before touching the throttle. It always seems to foul the middle cylinder, it fouled the mag side once or twice but never the pto side. Plugs are br9ecs. Dirty carbs? Bad gas? Bad plug boots? 
Clean the carburators, just beacuse you should clean them before the start of every season. Check the idle mix screw, perhaps idle mix is too rich.

My 700 did that all the time. Replaced all the plug caps and it fixed the fouling issue.

alright thanks guys, would you just reccomend NGK ones or stock?

The stock plug caps that came on the 2002 SRXs are very high quality and I would recommend them.

X3. The resistors that are built into the caps go bad just like all electrical equipment does.Cut some wire off before ya thread the new ones on to ensure your into good fresh wire.sideshowBob said:
