    I am experiencing some carburetor jettings problems with my xr650r. I need to know if I can fit a bigger carb.

    There are many issues that can cause backfire. Running out of fuel is one of them. Also; valves that are out of adjustment, incorrect jetting, dying spark plug, dirty carb, etc.

    Can some one show me what the plug colour should be, mine is a rusty colour all over?
