I just put a new Malossi 70cc kit on my honda PA50II, it says in the instructions to use premium gas in it. I don't really want to pay the extra money to buy premium gas if i don't need to. Will it knock if i don't use premium? Is there any other advantage to running premium?
PS- the box says that the compression ratio on the new cylinder is 10.5:1 I know that that is the biggest factor in the decision. I thought that it was pretty cool that it increased the compression, maybe they all do that, but I've never owned a moped before this so I wouldn't know.
