I was just wondering what grade of gas you guys put or should put in your Kats and what seems to make it run at its best...

The only time it is neccessary to use higher octane is if you are getting alot of knocking or pinging. I have a friend that is a senior executive for Texaco and he has told me this."You're going to learn to dicipline your image. You think I got where I am today because I dressed like Peter Pan here? Take a look at what I'm wearing people. You think anyone wants a roundhouse kick to the face while I'm wearing these bad boys? Forget about it."

I am sure that if you do a search on this you will find the answer, but the bottom line is this:
All you need to run is 87 octane. The Katana does NOT require higher octane fuel and it's a waste of money. 87 will provide you more HP and better fuel economy. High octane is designed to provide a slower burn in order to prevent detonation and in a lower compression engine it will not burn completely, resulting in less HP. A more efficient burn will also leave less deposits in the engine.
You guys can pay more if you want, but there is absolutely no need to do so with these bikes. This is fact, not just guess work. Bottom line is that if the motor is not experiencing detonation, then you don't need higher octane fuel.Ron

Yellowkat, you said when you downshift into 1st you get a different pinging sound that you don't get in the other gears. What are you doing when you get this sound? Slowing down, going at a steady speed , or accelerating gradually or hard?
You get a different pinging sound in the other gears?
First gear may have a different gear "whine" than the other gears, but thats from the transmission, not the combustion chambers. What rpm are you at (in first gear, and in the other gears) when this pinging occurs?
I think that if you had real pinging, it would happen in every gear when you tried to accelerate. And it would get worse as you open the throttle more. You'd know you have a real problem.
Try switching to a higher octane gas for one tank full.
