This is my 1987 Yamaha Yz 250 this bike has just been rebuilt with a new top end and new crank also new brakes wheel bearings and new swing arm bearings. This video was tests on the rebuild and tuning the carb. When the bike is started in the video it is a cold start and that smoke is from WD40 sprayed on pipe so it don't rust when it is stored.
