your thoughts on 87 octane gas

[tomheet]

I stopped by our local kymco mechanic, he adjusted my idle and mix screw for me in about 30 seconds. Now when I stop for a couple of minutes, it starts up on the first try, instead of 3 so I think he did something right.
  Then he tells me I should run 87 octane gas. Says it burns much better. I cringed at doing this "cause the manual says..." syndrome I have. It can't do anything bad for 1 tank, I figure. So I added 1 ounce of seafoam, and topped off the nearly empty tank with 87. After a couple of blocks, I heard a godawful vibration when really getting on the throttle, like it was really over-reving. I rocked side to side for a while, hoping I just needed to get the seafoam mixed good and proper. The noise went away soon after, so I guess it's all good.

What do you all think of 87 Oct... good. or bad idea?

I'm told that 87 works fine - but I stick with the 93 myself and don't do the seafoam thing.

I've thought about trying the 87, but it's been 2 years running 93 and I haven't had any issues so I'm not going to mess with success.

OS- can't say i'd blame you for not messing with what works. stick with it. I look at it as trouble shooting 1  step at a time. If it doesn't help, I'm going right back to the manual specs. And, I'm not trying my new  irridium plug untill I try the new gas first.

My scoot's too new to comment, but, yeah...they tried to tell me to run the 87 too.

The octane issue is one of those things where I don't know what to believe.

Some say using 93 is better, other say it can cause problems so use 87.

I remember the old days where I used to buy 86 octane at Beer World in Gainesville because it was cheap.

..tomheet...i've ran 93 octane from day one...

..got 54,000 kms on my 08 agility50...

..seafoam is a very good cleaner of carbon deposits in your combustion chamber and exhaust...


...a new scoot shouldn't need it for quite some time...i ran my new scoot for over 40,000 kms before i started needing it..but by then i REALLY needed a good carbon cleaning...

..unless you start doing some mods, and stand the chance of running rich while your tuning....use any system cleaner at your own discretion..if it sounds dirty..clean it...

[tomheet]

ah yes, I don't know but just guessing the  epa compliant carb regulations maybe overly complicate things for scooters. I'm no expert, but were carbs for dirt bikes or mopeds  this complicated in the 70's, 80's ?

[oswaldters]

To this point, I've used some sta-bil a couple of times over the 2 years I've being running the scoot when I thought I might have had some water in the tank but nothing else.

But I've got a long way to go before I reach 40,000 kms....

[wordslinger]

..the restrictions are for speed laws only..

..these scooters are engineered to perform much better than when they roll off the shop floor..

..that being said...every scoot has it's own relative personality..

[Rianna]

I wanna reach 1,000!  

So they think 87 is better, So they think 93 will hurt it? I'm not sure of their logic.

[oswaldters]

every scoot has it's own relative personality..

...or personality disorder in some cases...

[wordslinger]

...or personality disorder in some cases...

..yes...

[Rianna]

...or personality disorder in some cases...
Figures I would get the one with the Personality Disorder!!!

Forget seafoam, add some anti-depressents to the gas tank.
