My 1st bike years ago was a 2 stroke. I found out by accident that it would actually run on a 50/50 mixture of gas and heating oil. Didn't do much for it's performance.

So the last 2 weeks I've been testing on my way to work.
84/89/91/94 octane: full tank as the baseline, bike is still 100% stock, fresh oil change 20/50 Motul synth I used 20/50 Motul non-synth as the topup, new plug, new air filter, new chain. I get better mileage on 94 (one extra trip about 30kms) and the big difference is that at WOT (which I'm at for about 30 minuets each way every day) the engine will accelerate from 100-120kmh smoother. The GPS shows no other differences , but on the last couple days with the 94 I was 15 seconds quicker on my route(more likely draft! LOL) I'll say this , run what you want, I'll stay with the 94 it's not even a 1.50$ difference in the cost per tank and the hour meter is on the motor and it's running at WOT.

Grumpy, if you are referring to drafting other vehicles PLEASE DON'T. That can get you killed. Any junk on the road can be passed over by a vehicle and you won't see it in time to avoid it. Ride Safe. Login or Register to Remove Ads |

:nod: when I say draft , it's more like windbreaker and I'm not really in the draft ...trust me there is more then enough dead tire on my bit of highway to make sure I can see for miles and miles and miles and miles and miles (oHhh YEah)

http://www.faqs.org/faqs/autos/gasoline-faq/part1/ Subject: 3. What Advantage will I gain from reading this FAQ? This FAQ is intended to provide a fairly technical description of what gasoline contains, how it is specified, and how the properties affect the performance of your vehicle. The regulations governing gasoline have changed, and are continuing to change. These changes have made much of the traditional lore about gasoline obsolete. Motorists may wish to understand a little more about gasoline to ensure they obtain the best value, and the most appropriate fuel for their vehicle. There is no point in prematurely destroying your second most expensive purchase by using unsuitable fuel, just as there is no point in wasting hard-earned money on higher octane fuel that your automobile can not utilize. Note that this FAQ does not discuss the relative advantages of specific brands of gasolines, it is only intended to discuss the generic properties of gasolines.

As I've pointed out... and the linked article above clearly states...
There is no "end all, be all" answer. Reading the FULL article is strongly suggested. My wife's GZ seems to run hotter than others with the standard spark plug. Particularly in the summer, her bike will knock in lower RPMs while accelerating. Running 91 octane in her bike stops it. Every time I've put 87 in it, it knocks. All things considered? I run 91 on her bike. A little as its ridden and as little cost for her bike, its small insurance. The article also makes several references to the differences between "old engines and modern engines". While the GZ is relatively modern, it is also relatively old. An air cooled and carbuerated engine.. and while i may be wrong, I think the ignition advance is fairly static? That article suggests that if knock is experienced, you should experiment with fuels until you achieve a no-knock result and then stick with it. It has its purposes, but using a higher octane fuel is not exactly a performance enhancer. Running a HIGHER octane fuel should do no more damage than a minimum rated fuel. However, running a LOWER ocane rating than called for COULD lead to damage from engine knock. (or as stated in my wife's bike which tends to knock with 87) A particular brand of fuel is usually formulated the same across the board with the octane rating being the primary divider among them... until you get into "cleaning agents" and other additives.
