Hi Guys, I just put a new main jet in my 2009 YZ450, when I removed the carb I also took off the TPS (doh!). I am about to put the carb back on and wanted to know some information on how to properly set the TPS. There is still a green factory pen mark on the carb and TPS, but it is a thick line and I am not sure if it will be accurate. I read the adjustment process in the manual on page 6-10, It seems very involved. Could someone further explain this step: 7. Insert the thin electric conductors"2" (lead) into the throttle position sensor coupler "1", as shown, and connect the tester to them. Has anyone documented this with images or made a video of TPS adjustments? This shows a way to check the carb before you install it. Is this correct, if you do this do you also have to perform the adjustment on the bike? What will the happen if the TPS is not set correctly? What should I look out for? Thanks for any help.
