[Anatak]

I put 87 in my bike Sunday and it rides like crap. Its harder to start and run a little rough. I'm going back to 93. However, I have notice that 87 burns slower.

Really sutpid question from a newb here. Just trying to read through this and make some sense of it as a new katana rider.

I just bought an 88 kat 600, I've only had to fill it up once and was told to only put 93 oct premium fuel in the tank. Not having anything to compare it with, I can't say whether it's riding poorly or very well.

My question being, if I try 87 oct. fuel on my next fill up, could it damage the engine in any way I don't know about? Or is it a good thing to try and find what works best?

Thanks in advance for the help.

No such thing..
Oh unless it's the "do you want a car wash?" while filling up your motorcycle..

Unless there are some performance mods,
High compression pistons, igition advance etc..
89 will not hurt it.
87 won't hurt it either.. If you notice it's running poor
you can change back.

well, maybe I'm just not observative enough to notice but I've run all different octanes from many places and can't feel much difference at all, stock

I only run 93 when I'm fillin up w/my dad (HD does need 93)

maybe I'll just try running alchohol huh?

Well , I never could tell a difference between 87 and 93 either . I figured since I had a 771 kit I HAD to run 93 . But it turns out you DON'T have to if you don't use the thinner Wiseco gasket . Mine doesn't make that 13:1 compression , so 87 it is . Doing fine (relatively) , too . No odd noises I can tell , anyway .

You've been here a year?

Hmmm

I have a 06 katana, and I have been putting in 87. Should I be putting in a higher octane?

Nope. But buy good quality 87 octane gas (a brand with a decent detergent load).

I have been using 87 from chevron on the new bike, it likes it.
