Took me a whole day to remove the AIS, remove the air box snorkel, install new jets from GYTR and a pro moto billet silent insert. The new jets included are a 165 main and a 90 leak. After reading through the jetting section I was concerned about how the bike would feel after completion. To my surprise the throttle seems very responsive. Was only able to ride the bike a few blocks but could tell that it was a big improvement to ths stock. Did not notice any of the bog people have complained about and the need to move to a richer leak (#40). I will need to do a full ride for a better review. I have not yet cut the grey wire. I have mixed feeback on just how beneficial cutting the wire is. The majority of the peole here claim by its magic however I have heard that the performance gain is marginal but just allows for a slightly higher gain in rpm and is more suited for use with YZ cams. Any feedback on the grey wire would be apprpeciated.
