DB2 work started - Ducati.ms

Hello,

I started working on my DB2 (900 SS is almost finished).
In the parts list the fuel tank has a fuel sensor.
I don't have a fuel sensor on my DB2.
I noticed that the fuel cock is a normal number with a on, off and reserve.
So I was wondering what the fuel sensor is for ?

Another thing is that the previous owner ran a lot of extra electrical cables.
I have seen on my 900 SS that they ran extra cables to the intake manifolds for grounding but this seems excessive.
Does anybody have any comments ? (look at the picture please)

third question is
What replacement battery do you recommend ?

and lastly
this DB2 has the annoying side stand that folds in automatically.
My other DB2's side stand can stay folded out.
I understand that being able to drive with a folded out side stand is very dangerous but I wonder how many times someone dropped his bike because of the automatically folding side stand ?

this DB2 has Keihin FCR's installed.
the return fuel line goes into the air filters. That doesn't seem like a brilliant idea to me so I am asking for opinions on that. (picture 2)

I can't help you with any of the Bimota specific questions, but...

I bought my ST2 new and it had the auto-retracting sidestand. In over nine years and some 40k miles, I never had an issue with the stand. It was not until we got my wife's ST2 with a modified stand that stayed down that I realized I liked it better that way, so I modified mine. The only problem I had for a while with the ST2 was accidentally leaving the sidestand down while the bike was on the centerstand, then when dropping the bike off the centerstand, the sidestand would slam into the ground and I was running the risk of breaking the mounting boss on the engine case, but......you don't have a centerstand to worry about with a Bimota.

I've owned my DB2 since this spring and I've already dropped it two times thanks to the sidestand, those springs (there's two of them, one inside the other!) is way too strong. I managed to catch it the first time but not the second...

Where is the fuel-cock? do you have to take off the tank fairing to see it? I've looked but can't find it on my bike.

Hey Sad Glad

the fuel cock is visible and reachable from the left side

I attached the picture from the parts list of the tank.

When you get low on fuel do you have a warning light coming on ?

I will look for the difference between my first and second DB2 (at the moment they are in different places)
The first one does not retract the sidestand and I think the previous owner changed the connection point of the spring.

I modified mine shortly after I got it. You just have to move the top fixing point of the spring forward of the side stand pivot point. I don't have the bike anymore but here is a pic of a mod done to a Ducati 851. You can see the spring hanger now has an "S" bend in it to clear the stop that would normally cause the side stand to auto retract.

For the DB2 I can't remember if I just moved the top allen screw holding the spring by drilling and tapping the mounting bracket or fabricated up a new top mecahnism. Either way it only took 30 mins or so

Thanks, I found the fuel cock, it was well hidden behind the fairing and the fuel line. The level is pointing downwards, is it set on 'reserve' then? I couldn't see properly.

I don't have a low fuel level light and I don't think there should be one. I think I asked Redtop about it, at least I asked someone about it and he said there shouldn't be a warning light for low fuel on the DB2.

But I have a connector that's unplugged and it's in the area of the fuel cock, I couldn't see if it's the connector to the fuel level feeler (#8 on your pic). Do you know what the fuel level feeler do?

I think I have to do some bike exploring this winter

I also found an unplugged connector near the fuel cock.
I did not trace it back from where it comes.

Maybe the DB2 never came with a fuel sensor or maybe only European models came with a fuel cock ?

My '94 USA model has both a low fuel light and a two position petcock, off and on, for tank removal purposes only.

anatak · Aug 31st, 2010, 7:45 am

My fuel cock has 3 positions
on res off
so I guess that explains the second space designed for a sensor.
Probably only for US models.

on another note.
The magnetic oil filter plug is extremely tight. Any good hints to work it loose without damaging it ?

To disconnect the swing arm I need a hex 7 mm. Nowhere to be found in Japan. I guess I ll be looking to buy that online.

unless the snap on tool guy has it.

My bike has a low fuel light but it has never been very acurate. It comes on early. I read a lot about this in old posts I found in the micapeak forum. They are still there, just a lot of looking. I down loaded about 40 pages of stuff just about my bike or related items.

Also the bike will start without the clutch lever pulled in so that will take it off the side stand as well. Oooops
