Hello everyone!

I am new from North Carolina. I just traded a ttr225 for my first quad a 2001 400ex. It smokes from start up and smokes worse as you rev it. The good news is it runs…lol I figure it needs a top end I have never done one before so if anyone knows of threads they can point me to I would be grateful. All the plastic is in great condition lights work but the start button doesn’t work. I came across this site by googling that problem and noticed a lot of helpful people and some great threads.
