ok so i jsut got a 95 tomos sprint, i cna hear air coming out of this hole on the right hand side of the engine.
it looks like it can be a vent thing? but also the other side has a screw in it, i attached a pic to show the hole.
speed is still good, at around 30mph, 35 on tomos speedo.
do i need ot find a screw for this and am i hurtin anything with it not there??
