yes bro those two are symptoms and they should not be taken lightly i just hate mechanics
why do they disturb these settings i have picture proof of what he did i used to adjust cd70 or pridor
mixture myself but in cg carb mixture screw is underneath carb a bit difficult to access
and i bought bike used so did not think of noting its mixture screw settings else when i bought my last
bike cd70 i had noted its mixture settings
Picture when ruined settings you can see mixture screw is too much out
means it was too lean that is why faced backfiring & heating issue
picture after recent setting still needs little bit adjustment slight clock wise turn
but i am running it as its running fine
and this is picture of untouch mixture screw
Really hate mechanics why do they change settings mechanic i went is honda warranty mechanic
we go to tune our bikes to maintain it and keep it performing best but mechanics most of time
do reverse they ruin bike you see a little mistake has such an bad impact on bike performance
we hear this complain alot of backfiring & heating in cg & many might be just facing because of
nonsense of mechanic not only you listen backfire sound from silencer & extra heatup of engine
but loss in bike performance acceleration is affected as well
