If I had the money I would totally throw it at my bikes. Trying to get speed and often in my case operation for cheap/free is getting old, but I am learning a lot.
I think we are running into 2 different schools of thought here.
"Mopeds are toys" if a toy breaks so the fuck what. Nothing wrong with this view.
I however, for whatever reason have some pretty strong feelings for my bikes. I literally feel pain when one is fucked up.
Sometimes I envy people who can just say fuck it, its just a toy, I'm gonna ride it like I stole it.
