SuzukiSavage.com - What fuel grade ?

Bruno666 YaBB Newbies Offline SuzukiSavage.com Rocks! Posts: 28	What fuel grade ? 05/15/09 at 05:02:03 H.. I was just curious to know what fuel you guys use. I can´t seem to find what the Savage is built for and I would also like to hear from anyone that has done some performance mods.

Reply #1 - 05/15/09 at 05:16:25 Compression ratio is the primary factor is what fuel to use, and with just 8.5:1 in the Savage engine the basic 87 octane usually works just fine. I will use the higher octane fuel on occasion if I am going to work the engine hard and keep it pretty hot, but otherwise regular works ok.

Reply #3 - 05/15/09 at 06:04:51 I've found that my bike runs fine on 87, but now and then I run a tank of 89 just to see if there are any differences in performance. Have not seen any, buy makes me feel good.

Each bike will probably be different on what grade it likes (depending on mods and location). My 07 ran fine on 87 and 91 with stick muffler but did not like 93. 93 octane seemed to make the engine ping and not run as good. It prefers 87 after putting on the Super Trapp. I am running 6 disks and adjusted the air/fuel mix (didn't have to rejet).

Reply #6 - 05/15/09 at 06:22:32 Running 93 octane will give to a little less power because its like retarding the spark,It will run a little cooler because of that.The higher grade gas have more carb cleaners in them.

This question has come up a number of times in the past. Some members experience pre-ignition (pinging-dieseling) during hot days in traffic or extensive idling. I've experienced this problem under those conditions, and when crossing the desert in hot weather. Living in warm CA and never knowing what conditions I will encounter, I use Chevron 91 octane premium all the time. The bike gets such good MPG and since premium is only a few cents more per gallon, it makes no sense for me to allow the bike's piston to rattle.

Ran like poop.

Reply #13 - 05/15/09 at 07:48:27 It like any grade with the stock setup on mine, but after changing to KN air filter, mixture screw and white spacer. It doesn't like 91 anymore, it'll run, but seems to have less git up and go. Because I can't feel a difference between 87 and 89, I run 87- leaves more $$ for beer; an essential repair tool.

8.5:1 compression ratio, emission spark box=87 octane(pump reg)... if you get pinging or knock with that, you need a colder plug, not higher octane.... or maybe the ol' combustion chamber needs a good decarb..... running primo in a smog motor just coats your plugs with octane booster residue(pale freckles), that increases resistance of the airgap, giving a colder spark.....
