I haven't had enough time to go over this SB6 properly yet and certainly haven't had time to give it a descent run. The bike had been sitting unregistered and unridden for 3 years before i bought it, so I'm finding a few things that are probably due to sitting so long. Some of which i have already mentioned in other posts.

- Rear brake pressure switch not working.
- Clutch drags.
- Radiator fan does not cut in even when very hot. (near the red when sitting in traffic)
- Engine starts in gear even with clutch engaged. There's no switch on the clutch lever and i can't even find wires that would go to it.

Is there anything else in particular that i should look for or is there any 'normal' mods that need to be done to this bike?

Thanks in advance for your input.
Brian

Brake light pressure switch is a single banjo light switch quite commonly used in manufactures (ducati,aprilla,suzuki) they are either
M10 X 1.25 stainless steel banjo brake light switch
M10 X 1.00 stainless steel banjo brake light switch
dependant upon what Bimota had at the time.

Clutch drags could be due to bike sitting for a long time, plates
and friction discs may have to be removed and cleaned

Overheating problems can run from anything from faulty thermostat
(read through other SB6 posts) fan motor seized ( try turning blades by hand) faulty relays,etc

Engine starts in gear, sounds like previous owners have shorted out
switches and relays. When engine has started. leave side stand down and
put into gear, engine should cut out - if not side stand switch at top has either stuck in closed position or been shorted out.

There should be a side stand cut out switch (it a standard Suzuki part).

I think the fan sender is on the alloy part that sits above the cam cover, it's the part on the right with the wires attached.



Check there's power going into this and then try bridging it out.

I had a better look at the bike a few days ago. I shorted out the fan switch and the fan does work. Let the engine get hot and the actually does cut in, not until the needle reaches the red on the gauge but (like fish says above). I don't know the actual temp that the fan cuts in so this may be normal? I'll change the coolant and put some colder coolant in. Might even fit a switch to turn the fan on manually, not a bad idea fish, thanks.

"colder coolant" ???

That might be something I don't know about

I put some engine flush through then changed the oil and filter. I've taken it for a ride and the clutch may be a little better but still drags. I'll leave it till i have time to pull the clutch apart and inspect the plates and discs.
