2007 Yamaha XT 225 Serow!!!! Needed a carb rebuild kit after all these years. My kids last year left some small amount of gas inside and didn't run it dry like they should have. Kit is easy to install, you gotta know what you are doing, these carbs from mikuni have air diverter valve and vacuum diaphragm, be very careful if you try to do this yourself. Main and pilot are easy enough to replace. Pictures shown. I have been doing this for years! God bless you in Jesus name Amen
