Question about 2005 Ducati ST4s ABS

Regular fuel causing engine problems?

I just recently switched from premium to regular this past tank since I was kind of convinced by earlier posts on the topic that regular grade was just as good as premium for the monster. I had no problems at all for the first 50 miles of the tank but I also did not take my bike on the highway at all during those miles. Today however, I got on the highway and for about 25 miles my engine kept (stalling/cutting out?) and then coming back on again after a few seconds. The engine light would come on, the rpms would drop off for about 1 second and then the engine would come back on again. Almost like it was running out of gas but there was plenty of gas left. It happened about 10 times and when I finally got to a gas station I filled it up again on premium. On the way back home the stalling problem happened one time and then I had no problems after that.

I've never heard of anyone having issues like that from lower octane, and I never have with my carbed bike. I'd rather think you got a bit of water somewhere...possibly in the regular fuel...or it was already in the tank and the fuel is just a confusing factor. Use a little dry-gas and try it again.

What is the best fuel to put in the tank?


Always, always put Premium fuel in your Harley. Regular and even medium grade fuel will cause spark knock or pinging in the engine. These machine need high octane.

2001 honda shadow what kind if fuel should i use


Regular unleaded should work well in your motorcycle; it may actually start and run better with regular than with premium gasoline.

The big wild card, however, is the amount of ethanol in the gas you are buying. Your bike would definitely run best on "pure" gasoline that contains little or no ethanol, but that's getting harder and harder to find. Personally, I have noticed that my bikes have started harder and run worse as the ethanol content in gasoline has increased. That's one reason I actually recommend staying away from premium, which sometimes has more ethanol in it than regular (it raises octane). I prefer to keep my bikes stock, rather than messing with the carb jets to compensate for the different performance curve of ethanol-blend gas.

If it's available in your area, you might try running your bike with some Cam2 racing gasoline to see if that makes a difference. You don't need the extra octane in that fuel, and some varieties of that fuel may still contain lead (a no-no for your engine), but it doesn't contain ethanol, as far as I know. Double-check with whoever is selling this fuel in your area to make sure you're getting the unleaded stuff. If you find that your bike runs well with this fuel, you might consider blending a bit of it with pump gas on going-forward basis.

Did you do an oil change recently? Sometimes a motor cycles clutch shares the oil with the engine and a different kind of oil then the bike requires will cause the clutch to slip. This happens alot especially if someone switches to some types of synthetic oil when the bike had regular oil before the oil change.

First, I would try mixing in some seafoam...also, are you running premium fuel, or regular?

Motorcycle engines are designed for the higher octane ratings, and running regular or mid grade will clog your injectors.

If you run the seafoam through the gas, be sure to do it in your driveway, bike on stand, in neutral. You might have to hold the throttle open a little, depending on what concetration you mix it in at. If the problem is a clogged injector, that will clean it out.

I would also look at your fuel filter and lines from the tank, check for debris that could be impeding the flow of fuel.

Gas


I got on the highway and for about 25 miles my engine kept (stalling/cutting out?) and then coming back on again after a few seconds. The engine light would come on the rpms would drop off for about 1 second and then the engine would come back on again. Almost like it was running out of gas but there was plenty of gas left. It happened about 10 times and when I finally got to a gas station I filled it up again on premium. On the way back home the stalling problem happened one time and then I had no problems after that. Has anyone else had this problem with regular 87 octane gasoline? By the way I ride a 695 with a Termignoni exhaust system. The engine was cold when the stalling started happening but kept occurring even when the temp was running 212. I would appreciate any comments and advice.I've never heard of anyone having issues like that from lower octane and I never have with my carbed bike. I'd rather think you got a bit of water somewhere...possibly in the regular fuel...or it was already in the tank and the fuel is just a confusing factor. Use a little dry-gas and try it again.,,,
