As there are a few 325s about, and the 350 kit is selling, I thought I should begin a thread about carb jetting for the big bore engines. Those of us who have been running the 325 for a while may have noticed they run a bit rich if the jetting is left standard. Sort of the opposite of what you might expect (coun...

Recurring pilot jet plugged

I have a 2006 TTR 250 that sat for a few years. After it was taken out of storage, the carb was soaked and rebuilt (All balls kit), fuel lines replaced, inline fuel filter replaced, etc. The pilot jet continually plugs up. I've had the carb off countless times (I've actually gotten pretty good at it)....
