What speeds are you shifting? Has it got the stock muffler? It's a low tech, low compression, low octane fuel using machine.

Reply #3 - 08/20/15 at 21:14:14 I have only put about 1000 miles on it. Got it this spring. I shift at different speeds depending on the roads I am riding, but I don't "lug it". I have the dyna muffler on it, but have not re jetted. Still running the stock air filter.

Reply #4 - 08/20/15 at 21:25:08 I THINK the 86 has reasonable jets for a Dyna, especially if it's got a stock filter. I don't know you or YOUR bike, but I am pretty familiar with the brand.

I want to start a new saying...

If it's under nine, regular is fine...

It may not be precisely accurate,.. but, "premium" "high test", "super".. is just regular gas, with an anti-knock additive...
It don't make power,... and it does nothing good, if your compression doesn't per-detonate the fuel...
....(it's a flame retardant additive)... Undecided

...
It's not magic...

We, have a low compression engine... it does not make enough pressure to cause per-detonation...

You are replacing fuel, with an anti-knock agent...
Only fuel burns...

Do the math... Huh

...

Also,... in this day of high fuel prices,... Few people buy "premium" fuels... so they sit in the station tanks longer...
That can't be good... old gas, is bad gas..

Regular is fine,... if you're under nine...

...(It might be ten)... Undecided

...

Ludicrous Speed !... ... Huh

As Serowbot said....our bike is a low compression engine and it is supposed to run regular grade gas (87). The higher grade fuels are more resistant to knocking/detonation from higher compression ratios and don't add any power.

Different fuel suppliers do put different additive packages in the fuel however, and if you go buy the "Top Shelf" fuels like Shell and Chevron they can have 4 times as much of the additives that keep the carbon from building up in an engine.....cheap gas from discount stations only put in the government mandated minimum amounts of the additives - and this minimum amount most likely isn't enough to keep our primitive engine clean inside. If you have to run 93 in your Savage to keep it from knocking....I would believe you might have a carbon build up problem in the engine.

I did a long term fuel test and did find that the premium fuel deteriorated the fastest....and I suspect that the rumor that the premium fuel may be old when you buy it is most likely correct.

av fuel 100LL. that is very high in led must use iridium plug or clean it on a regular basis. on the auto fuel rating method it is around 93 oct . i use it because no ethanol ,never gums up carbs ,and the valves love all the cushion of all the led . i also live in a airpark with a 10,000 gal tank that we sell at cost to our homeowners .i use it in everything that does not have a cat converter

Well sure it does.....I don't believe Suzuki has changed the carb to account for the fact that most bikes are using ethahol laced fuel (E10). I am pretty sure the TEV valve in the carb would work better without any ethanol in the fuel, and the bike would not pop and bang as much when you let off the etrottle if we all used ethanol free gas.

In minnesota we have sometimes the option for Non Oxy or non oxygenated gas. Usually 90 or 91 octane. It is only legal in small engines, off road vehicles, collector cars, and MOTORCYCLES. I swear by it for my lawn mower etc and the bikes. It is far better on the carbs. Today's gas has so many crap additives that can gum up a carb if you are not riding very regularily that it isn't even funny. I have been told (don't know if it is true but I believe it) that today's gas can go bad (many volitiles evaporate) in as little as 3 weeks.

I got sick of cleaning carbs and I swear buy it now. Buy it if you can get it.
