I recently changed the oil, spark plugs and battery on my bike, it worked for a few days and rode approx 30km with no issues. I noticed i had filled the oil over the half way mark, to more than full (while on centre stand). I took it out yesterday for a short ride , and experienced throttle problems, engine revved to about 7k then wouldnt go further. Then slowed the revs down for a turn, then it stalled. It would not start again even with the choke pulled fully in. It starts if i leave the bike sitting for an hr or so. I am not comfortable riding the bike to a mechanic fearing it would stall again. What could have caused this? Also, what problems could overfilling the oil cause? Thanks.
