Shimmed my needles, but didn't need to.
Today's project was to shim the needles on my 2009 250r. As first time ever taking off my gas tank, had some difficulties on some hoses & weird clamps. When I got to the carbs, I carefully tried to not strip the screws as everyone had advised, lol. Then when I pulled the cover & spring out. I took out the diaphragm, just to check if it was shimmed already by the previous owner. & Unfortunately, it was & had 2 washers ! Meaning, I didn't even have to go through the trouble of tearing the whole bike down, but hey... I know how to do it for the future. I would make a video the next time I do it, for those who can't seem to trust themselves to do it. I ended up just adding 1 more washer, because my DanMoto Exhaust comes in tomorrow.

Checking to see if the PO removed the snorkel or not would have been a good hint.

so to recap, pilot jet determines the lowest amount of gas going into the air stream which is typically at idle with no throttle. the main jet determines the largest amount of gas going into the air stream which is typically at max rpm wide open throttle. the needle shape and height determine the transition between those two jets. gasIntoIntakeTotal = slowJet + ( fastJet * (needleTransition+needleHeight)) where needleTransition is 0.0 to 1.0 based on the vacuum range of the engine and the needleHeight is your change from washers or clips which is a percentage of the total needle travel (also in 0 to 1 domain)

Nice. I was hesitant at first when I shimmed mine because I felt I wasn't as mechanically inclined as I thought. But all went well and now I feel like I'm that much more closer with my bike now The DIY threads here are awesome!
