Bimota Forum

So, yesterday I tuned my carbs with a Dynojet kit stage 1 with 144 main jets to begin. The kit is sold with 150 mm jets too. I think it's a bit too large.

On the worshop stand the carbs seem to work well. Now I have to improve them on the road. I will tell you more in few days.

Before riding, I would like to control carbs synchronization.

I have a carburetor vacuum synchronizer (a "carbtune") and I've already synchronized MIKUNI carbs on a ducati 900ss. Very easy.

But I don't understand how to proceed with the Mantra because the depression screw of the front cylinder is connected to the fuel pump.

To synchronise the carbs you need to plug the tool on both admission pipes, so you need two holes and the fuel pump...

On the Mantra you can see a hole on the admission pipe for the rear cylinder, but nothing for the front cylinder except the fuel pump plug...

There's nothing about that in the worshop book.

Is there any Bimota special tool to plug the carbtune on the front depression pipe ?

How do you proceed on your mantras.

Thanks a lot.

If I understand your idea, I don't need to connect the fuel pump to the carbs.

I can connect directly the external fuel tank at high level to the carbs and it'is enough to run them.

I will try this week end and let you know...

Hi, My name is Bernard, I know this is a long shot, after reading your question , I noticed you have a Workshop Manual for a DB3 Mantra? I have put an on this forum for a Manual but no luck, I would like to ask if you would Photocopy the Wiring Diagram for me? I will pay you for it. As I am having trouble with some of the Dash Board Lights, Oil Light, Charge Light, there is power to the bulb holders, and the Bulbs are ok, but they are not Lighting up, so I need a wiring Diagram, could you please hhelp/ Regards Bernard.

Of course Bernard, send me your email by PM.

I think your plastic bulbs holders are dead... You can find them on the bay.
