I just purchased a couple of weeks ago a new 2007 blaster leftover stock from Pacific yamaha in Richmond B.C. Canada.I understand alot of people think 06 was the last year of blasters but in Canada we had 07's for our last year.It is brand new and had never been started.Pretty cool in 2010 almost 2011 to start a new blaster for the first time considering there not made anymore.It is a white and black one and I will post photos of it tomorrow.I've only ran it once and have a question.If I take off the airbox lid do I have to rejet or could I just adjust the air screw to let more fuel in so not to lean?I'm new to blasters and atv"s in general so all help is greatly appreciated.\Thanks.
