adrenalnjunky 10 Posted November 28, 2012 Hey there everyone. Father in law picked up a used 2000 BB400 4x2 - motor runs well, no smoking. Little cold natured, but starts easy enough on full choke, and as it warms up you can back the choke off to a normal idle. Not uncommon for older carbed bikes/quads. but - cold or hot, this thing is sometimes a real pain to get into reverse or 1st without rocking it back and forth a good bit. as it warms up, again it acts better,but doesn't get perfect. When moving,it shifts up and down smoothly and accurately with no signs of clutch slipping. Oil looks good and clean. I see the clutch adjustment on the left side crankcase - but before I go screwing with anything, I'd like some other's opinions on what I might do to make the engagement easier. thanks, Chris Share this post Link to post Share on other sites Like what you are reading?
