Question about 2003 Ducati Monster 620 i.e.

1 Answer

Gas I know there has been a topic posted on grades of fuel but I didn't read about anyone having problems with regular fuel. 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. 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.,,,

Does my 1500 vulcan nomad require regular gas or the premium octain grade gas


regular gas will not hurt your bike but the higher grade you put in it the better it is for it, but it is not a performance motor or a race bike so you will be fine with a lower grade fuel.

I have a 1984 suzuki rm 125 it has always ran good for me. until recently it just putts and runs for maybe 20 secounds and then stalls. i tried to run start it and it kinda fired up but there was way more...


Are you mixing regular motor oil in the fuel? Doesn't this bike have a reservoir for 2-stroke oil? You must use 2-stroke oil in that reservoir. Buy it online if you can't find it locally.

NO PROBLEMS JUST WANT TO KNOW WHAT GRADE FUEL FOR MY 2005 SUZIKI 50 T MOTORCYCLE TO USE


Regular unleaded will be fine. An old rule of thumb...if compression ratio is below 10:1 regular is fine. Use premium over 10:1 compression. You Suzuki is 9.4:1 and will run fine on regular unleaded. This should be listed in the owners manual and if you don't have one I would encourage you to go to a Suzuki dealer and order one for a small charge.

Hope this helps!

Fuel overflow problem with 2007 roadstar silverado 1700, gas runs out the carburator onto the ground--sometimes won't crank--


Gas running out of the carb indicates that the internal float valve is not shutting off the flow when the float bowl fills up. Might need cleaned; might need a new float valve assembly. Not cranking is an electrical problem. If you mean that the engine cranks over but doesn't start - then this could be a related carb problem. Take the bike to a reputable repair center near you.

Regular fuel causing engine problems?

Petrol Pump


once the tank was topped up away we went again performance restored. The topic of fuel delivery has been touched before I know. The carbs float level and jets are OK so we can assume that the fuel delivery side of things is up to spec. I remember having a conversation with someone a few years ago on this topic and their comment was that either in the wiring loom or in the wiring diagram there was provision for an electric fuel pump. Can anybody confirm this? The problem is not new, I've noticed it on many previouse occasions, offcourse only on WOT applications such as Eastern Creeks long straight. To rectify the problem I propose to fit a low pressure electric fuel pump in the fuel pipe. It would need to be relatively small ofcourse. Any suggestions? ,I remember reading about the Gowanlock blokes running the DB1 at Bathurst and having similar problems,it took them ages to sort, it turned out to be the tank breather not flowing enough.How close to reserve was the fuel level.How many laps had you done,sounds like you think the head of the tank eg gravity feed is insuficent to meet demand after some fuel is used.I am sure you have thought about the obvious stuff eg ,,,

Fuel problem


the bike will start but not run for long especially if I roll the throttle a bit. When turning the key and flipping the kill switch to on I can hear the fuel pump. I removed the fuel pump assembly and checked for holes or cracks in the lines and none are present. Does anyone know if the fuel/air separator can go bad? I have tried putting an extra quick disconnect to an extra fuel line to see if I can get any fuel out put and I get nothing. Do fuel pumps get clogged? Any words of wisdom would be great before I run out and buy an new fuel pump.Try running the bike with the gascap open and see to rule out that the air supply is clogged.,,,
