My daughter has a 96 Yamaha RT-100 that she chases me down the trails on. Seems the 2 Stroke oil level in the reservoir has gone down very little in a multitude of rides. Was wondering if it would be possible to disconnect the reservoir and just premix the gas without ill consequences, and if so.....what ratio would be adequate. May be paranoid, but I would rather mix than worry about seizure. Slap me if I am stupid on this.
