Aprilia sr 50 not running right

SOURCE: aprilia sr 50

if you hear a hum while tryimg to start then the starter is okay the problem will be in the main or secondary(upper or lower idle gear) starter gear

SOURCE: need to know how much oil is in the forks of an aprilia sr50 please

front fork capacity is 285 cc per leg, but you need to take the spring out and fully extend the forks and measure 140mm from the top and thats where your oil needs to sit.

Hi and welcome to FixYa,

Jet size would depend which carb is installed, a Dellorto 34mm?

Initially, check the sparkplug tip colors. If very light brown to almost whitish, then lean mix; too much air, too little gas. Try raising the needle if if has notches and moving the e-clip. If fixed, use small thin washers. The basic idea is to make the needle rise early on throttle movement.

If an aftermarket open breather air filter is installed, then it would be causing the lean mix, too much air. Restrict the filter by adding temporarily upholstery foam to experiment at which thickness the flatspot would disappear.

Good luck and thank you for asking FixYa. Happy Holidays.
