I just installed a WB xcr on my '06 250x and the instructions stated I could use the stock jetting, but that sounded wrong. I figured Im making a lean engine even leaner with the pipe, so I changed the jetting to 42p and 135 main. I also cut the top of the airbox, but no other mods. On start up, I didnt have to use the choke and noticed the idle was a little high after a 5 min ride. Any suggestions? Should i just adjust the idle speed and call it a day? Thanks in advance.
