rpms drop when i turn lights on.

[aztwin350]

i dont do a lot of riding at night but just wanted to see if i could avoid a problem down the road. i notice when i turn the lights on( i think theyre trail techs attatched to the handlebars) the rpms drop down at idle and low rpm. is this normal. these are the lights that were on it since i bought it so not sure how stock lights affect rpm. just seeing if i should replace them or something before its a problem

You have a bad connection or a bad stator.

It is normal. It takes effort to generate electricity so when your using the headlights its going to cause the rpm to slightly drop.
