Premium gas

Capri,

I was in Beach Boulevard Yamaha when I was in Jacksonville. Bought tires there for my Liner. My buddy bought two bikes there. I do remember they recomend premium fuel for all bikes. I used it in my 1100 for a while then went back to regular.

This discussion had has gone on here and other blogs for ever. And not solved. Lately I saw where premium contributes to blueing of exhaust pipes. But I have seen that premium burns cooler. We do know it burns slower.

There seems to be no noticable advantage to premium and no loss of anything with regular if the bike is recomended for regular. So if you do not gain mileage or performance why spend the money? For my Liner Yamaha recomends premium so I use it. The cost is only 60 to 80 cents per fill up so money is not an issue.

I see Harley recomends premium for their bikes now.

My thought, use what the manufacturer recomends, they are the ones with the funny shaped heads.

Check your owners manual (if you have one). The recommended type of fuel for your bike is listed in it. Pretty sure the OEM knows better than all of us! ;)

This is a ten year old thread. if you have question about fuel I would ask it in a new thread.

I have a 2005 Midnight and use 93 Octane, ethanol free since its carburated. Fuel Inj can use 87 or up.
Octane is going to be more important for higher compression engines. Like others have said, find a copy of the owners manual and look in there. My guess is it's going to say 87 for both carb'd and FI models.
