87 or 91 Octane gas in the KLX?
Is it better to have the 91 or 87 octane gas in the KLX? I've asked at my dealer they said 87 because it's better on the spark plug, although I've read only that it doesn't do anything, except help the engine run better and perform better.
I know with all you KLX power crazy people on the forums one of you must all know if it's actually bad or not. If it's good, does it actually help the engine a lot for a better combustion or no differance?
Thanks,

I'm sure you'll get a variety of answers. I used to use regular unleaded and was happy with it. However, after I rejetted I noticed a slight stutter between 7,000-7,500 RPMs. I found when I use high octane it all but removes that stutter.

If its built for 91 the ignition most likely performs best on 91. 91 is alao better in warmer rides to avoid detonation incase your spark plug gets hot enough to act like a glow plug. I run 87 in cooler monts 91 in the summer

Unfortunately around here ethanol is in all the grades, the only place to get non ethanol is from the bulk plant or a commercial card lock station, and those are few and far in between.

I use 91 octane because it's the only one without ethanol in around here. I also avoid ethanol since I don't use my bike that often and I've also heard some bad stories about ethanol and plastic tank like the IMS.
