Sport exhaust slows scoot down

I am going to pull the plug out this morning, will post a pic

I forgot to make a picture lol, looked like she was running a bit lean, went to the local moped shop to get a #85 jet, unfortunate me, out of stock.. Just ordered one online, hopefully I`ll get that one soon.

Although I don`t really know if it should make a difference, am currently going about 70km/h (43mp/h) on a smooth flat asphalt road with some negligible back-wind hehe 


Also tried to attempt a oil change, but couldn`t get the drain bolt loose  tried to use some WD-40 on it with no success. Anyone got some tips as to how to remove the bolt?

[Mr. Paul]

Try using a six point socket (NEVER a 12-point)  and gently tap the end of the ratchet with a small hammer in the direction to loosen it. Be careful not to strip the bolt. Should break it loose. I am surprised it is on so tight since you have changed the oil fairly recently. When you put it back on check to make sure it has a crush washer. I suspect it does not. Good luck!
