I was using 86 like the manual says but got a tap,tap,tap so I went to middle grade (I try to use Moble) and seems to have cleared up. What grade do you use?

There's been a lot of discussion about different fuel grades, which seem to vary a bit depending on where you live. The best advice is to use whatever makes your scoot the happiest.

 
Welcome, ibsunburnt!

Yes, yes, yes.

Reminds me of my boss....

Oh yeah, welcome!!!

87 Octane here. Never a ping nor pop. These octane threads can get quite interesting sometimes, so fasten your safety belt!

 
You can do a SEARCH and read countless threads on his stuff. You might want to read a little deeper.

Just stay away from that Cornohol. What is that? E85 or something? Casey's sells gasohol as premium cheaper than regular octane, and I put that in once. Seems to run OK in a pinch. But otherwise I stick with 87. Which this hour is 2.79 in these parts.

 
89. My FJR does a little pinging in 90+ heat with 87. When it cools off, I'll try a tank of 87 and see if the rattle returns.

 
I use gasohol (10%) here in Iowa and it seems to run fine. Ian

 
Thanks for all the great comments on my graduation picture and the warm welcomes. It was about time I joined the forum.

Well gotta ride were (and my wife ibsunburnt2) going up to Roosevelt Lake, hope to take some nice pictures. Thanks for all the great input.

 
I use a minimun of a non ethanol mid grade fuel. I feel that once the tank heats up, I need the extra octane to offset the potential vaporlock/ loss of effective octane rating that coffee temp gas suffers from. :erm:

I wonder if the Yamaha engineers take that minor flaw(tank cooking), into account when they dynotest their engines? :huh:

I've always wondered if switching grades frequently can cause problems. Can bikes be finicky about sticking to one grade? I have had several cars that seemed to be.

 
I use mid grade (89). I know the manual says 87, it just gives me a little more comfort (don't know why).

 
Wow, guess I'm waisting money, I only burn 93 octane. :huh:
Same here (except in CA it only goes up to 91 Octane). I guess you learn something new all the time on this forum. Looks like I'll be trying the lower octane next time...
