If you add a FCR carb, exhaust, and all other basic mods to the 400sm, does it need premium gas?
nodont you get more hp for the higher octane fuel tho? i.e premium goes zoom zoom instead of shit gas going zoom?
only in instances that REQUIRE premium gas. high compression, high boost, retardedly lean fuel/air mixture, etc. Putting 110 octane racing fuel into a 5 hp briggs and stratton isn't going to magically make it an 8 hp motor.dont you get more hp for the higher octane fuel tho? i.e premium goes zoom zoom instead of shit gas going zoom?
That's not entirely true... It's not "BAD", you just may not notice a significant difference. Higher octane ratings basically equate to a higher percentage of iso-octane by volume. In simple terms, it's a rating of how stable the fuel is (i.e. resistant to auto-ignition).However, despite the myth, putting premium gas in a car that needs regular gas is a bad idea as well, it's made to be compressed more and may not burn enough.
its all in your head...if it really does run better, then you have something wrong with your engine ie. for some reason, your mixture is pre-igniting. It could be a large amount of carbon buildup is causing hot spots in your cylinder. Maybe your bike is running really hot causing the pinging. If your engine in your DRZ S is stock, there is NO WAY that your bike will run better on 93 with stock compression and ignition timing. It's basic science...I've noticed that with my old DRZ S and now with my SM it just flat runs better with 93 octane as opposed to 87.I don't really know why,but for some reason it does enough to make me pay the extra money for a tiny bit more zip.
Why would I pay 30 more cents for fuel that will make less power, make my bike feel more sluggish and burn less clean???its like 30cents. might as well you cheap ass's
:lol: yup, I used to see the same thing all the time!This reminds me of my friends. They would run their cars out of gas, then put in 20 liters of premium in, and then a WHOLE bottle of octane booster into the tank before heading to the drag strip for street legal night. They thought their cars would run so much better. Stock motors too. When I protested they looked and laughed at me like I was a moron.

I used to do that, as well. Though I was running a road course for 40 minutes at a time in the desert. My thought was that, since the car was running on the verge of overheating (or running on the edge of the red...I HATE idiot gagues) for about 30 of the 40 minutes, it was a bit of piece of mind. I wouldn't even think about doing that at the drag strip. 9-20 seconds of "hard driving, followed by 60+ minuted of cool down....:headshakeThis reminds me of my friends.
