Older the bike the higher the octane?

[kx125412]

One of my friends was telling me the other day that he heard the older the bike, the higher the octane requirements. I just wanted to know if this was true or not as I have an 82' RM 125 that will be running regular pump gas because my dads too cheap and if I offer to pay for it he gets mad anyways.

Does it run bad on pump gas?

...the older the bike, the higher the octane requirements.

I hope that ain't true! :yikes:

That doesn't make much sense to me since they had crappier fuel back then and the bikes ran just fine. I would just run 93, unless of course it ran bad on pump gas. And in that situation i would try 110.

They had MUCH BETTER fuel back before the EPA put reformulation standards in place.
