Question about 1989 Yamaha Xv 250 Virago S
I took mine apart to clean the varnish out of the carburetor. Re-assembled and installed. Would not rev off of idle. Struggled with the main jet, thinking that was the issue. NOT. Found it to be the brass sleeve that surrounds the main needle (slide needle). The brass sleeve was not lined up correctly. It MUST be lined up with a small pin at the bottom of the casting. Once I got that lined up correctly, runs great! Fuel was not being pulled through the main jet since the fuel port on the slide-sleeve was improperly aligned.

Check the air filter is not obstructed or dirty. if thats ok then it is more than likely the carbs that need attention/resetting/cleaning out
