My wind bike seems to be having more black colored smoke emissions? whats the problem? the valve was mop already and adjusted.
I am not familiar with your Baja Wind 125 motorcycle, however, normally, black smoke is associated with too much unburned fuel in the exhaust - too rich a mixture. Is your choke fully open when this is happening? Are yo usure? Remove and examine your spark plug(s). I expect they will be sooty sooty black. Is your air filter clean, the air path completely unobstructed? Have you messed with the fuel adjustment? (I am not familiar with the term 'mop') Is your bike equipped with a Cat Converter? If so (not likely ...) it may have to be cleaned or replaced.
Some times, black smoke or sootie plugs results from using too low a gear, not running the engine fast enough for the riding conditions. Usually, the engine will buck if you are expecting too much from it by being in too high a gear. This is a very rare condition, having too low RPM for conditions.
FYI, Black smoke = too much fuel, Gray or Blue smoke = burning oil (worn rings?), White smoke (in water cooled engines) = water in the oil, blown head gasket or other trouble.
If your bike was recently serviced, I suggest you return to the mechanic and have them take another look at your motorcycle. If not, this may not be a bad idea anyway. You do want your motorcycle to perform optimally, right? Best ride and economical operation = most fun.
Some other things you can try, get a hotter plug. Replace the air filter.
I hope this helps you with your Black Smoke issue.
