Is that some rust I see Oily 
I was starting to think you were a perfectionist 
Always good to have something else to do when you get back....
Have a good trip

...I see no rust
Stains from welding the alminium swingarm which I cleaned off as soon as I saw the picture and welding/heat marks on the stainless paddock stand.......
where else?

Fortunately my cave doesn't suffer from damp but I bolted the engine in a bit quick just in case
Cooling system jigsaw was so much easier to sort without that bloody great, pointless web in the way.......
...can't do much more with it up on my desk, time for a hernia and lift it down onto the bike bench
another view of the cooling system, the thermostat is no longer wedged (literally) between the engine and the frame
...Got to get a move on, the new, new wheels should be here tomorrow |
in the first picture I see the cooling pipes routing I've found on my sb6, and that's different from the Bimota part list...
In bimota diagram the thermostat bypass (the smaller pipe) goes straight to the pump inlet on the engine side... as in "bypass mode" I would like to grow up the cooling temperature avoiding the radiator...
In the picture above in the "bypass mode" the coolant flows towards the radiator as in the "90° mode".
am I missing something (as usual ) ?

Firstly.........
I must be missing something
What is "grow up the temperature"?
Secondly...beware Bimota's parts lists
The idea of the bypass is to bypass the thermostat so at least some coolant will be circulating before your engine gets hot enough to open the thermostat.
What your talking about will bypass the radiator which will result in the engine warming up much quicker (?) in theory. Right?.
Trouble is......
once the engine has got up to temperature and opened the thermostat, and your caning it over the mountain in the IOM.......
Half of your coolant is still not going through the radiator, it's bypassing it.
Some people already have heat issues with their SB6 hence changing to a muzzy fan and a lower rated fan switch......Following Bimota's parts list COULD (I haven't tried it) make things worse.
The way to go to heat things up quicker and control the temperature better when the engine is up to temperature is to find a bigger, better thermostat and throw away the bypass
To date...I still haven't found a suitable bigger, better thermostat and it's now getting urgent

I know my english is far away from being technical...
I mean that this Bypass is a false bypass, as the bypassed coolant flows into the radiator. In the bimota diagram (wrong, but with sense) the coolant remain in the engine path increasing temperature at every "lap"...
I will take off the thermostat and clog the tiny pipe in the metal hose.
I think I will not use my bim in hard winter or I'll warm it up a little more before riding...
... and my TT is over the Appennini

Normally...I would agree with you BUT in this instance, I think the by-pass is there because the thermostat doesn't flow enough coolant. It is way too small. It is less than 1/2 the size of the GSXR 1100(which has an internal bleed hole...Bypass). In my humble opinion, I think that Suzuki Sans design departed has a few more resources than Bimota ever did or will have.
I'm thinking that if you block the by-pass, you will only flow half the amount of water
I'm running the "big bore" without a thermostat at the moment and it never gets close to warm (in the UK ). Which needs to be remedied soon.
I still think the answer lies in a bigger better thermostat and then there will be no need for the silly by-pass

I see...
but I would put a simple alluminium pipe in place of thermostat... so the amount of flowing water would be more than in stock conditions...
I still don't understand how this kind of thermostat-bypass would help to reach the right operating temp if all the liquid flows through the radiator as if I had a simple pipe in place of the Thermo...

ok....
all the coolant runs through the thermostat (except when it's closed). The thermostat, even when fully open, is too small to flow enough coolant to keep things coool. So, Bimota, when they realised this, fitted a big bore bypass which runs parallel to the thermostat (another reactive bodge, sorry...solution). It is now flowing twice as much coolant except when the thermostat is closed then it's not flowing enough coolant so the engine heats up, the thermostat opens and we're flowing twice as much coolant again....simples
If you remove the thermostat, which I did on the big bore (because someone had hammered a screwdriver through it  ) The engine never gets up to temperature, at least in the UK

I think the easiest way to explain this would be to stop calling this a "by-pass" and call it by it's proper name.......A Bimota Bodge
I'm not the only person running a SB6 without a thermostat....
http://www.bimotaforum.co.uk/viewtopic.php?t=2036&highlight=thermostat
...Which is OK on hot summer days (UK) but any less temperature and the engine does not get up to a decent operating temp

mmm, I'm in a southern country but Africa is still far from here and in spring days I could have the same problem...
I'll try to check the thermo and cleaning throwing some boiling vinegar (mine was full of green kriptonite or something lookalike)
in the meantime I'll search for a spare part (not the original, maybe an assembled one with a 35mm inlet and a 85? ° degrees switch)

...Boiling vinegar is your friend
...Let me know when you find an alternative

I wish photobucket would perfect ... change their website
This might help / confirm things
