hi all just seen this chat was after a bit of info if some one can help , what is the smallest cca that will start a 1200 the reason for this is iam trying to hide the battery in the seat hump on my motodd the smaller the better thanks stuart
 
180CCA will do the job. But .... things like compression ratio; newness (tightness) of engine; condition of starter; ambient temp all have a part to play. Not to mention starter cable condition.
Although I'm not a fan, a LiFePO4 (lithium) battery may be the solution

My 1200 Motodd with Red's H/C pistons cranks over using a really small lithium battery rated at 290cca. That battery would be 6 years old now and sat on a shelf for 18 months while I had some frame repairs done. It cranked the motor over without a recharge. For a battery that weighs 700 grams I'm impressed.
 
When I drive my 750´s hard it´s normal, that the motor "sweats" some oil/water-emulsion out of the hose on the top at the cylinderhat.

For the bikes without airfilter, I ad an Ducati part behind the smaler battery. It is only straped. The hose from the head goes inside the top of the one half, beside on the other halfe is the exit for the hose with clean air that goes behind. 1 or 2 times a year you have to drain the water/oil emuslion. Works fine.

Why don't you just exit the breather all the time to the atmosphere instead of just once or twice a year?
I don't get it.

When everyone argues like this, we have exactly the situation we are in.
You have to start at some point ..... Everyone has to decide for themselves.
I cannot complain about grievances and contribute to the problem myself.

Our children will have big problems, and not just because of climate change.

- Fertile arable land is only about 10-20 cm thick with us and is constantly decreasing.
- Our drinking water is getting less and less.
- Allready today we have drug residues and microplastics in the groundwater.
- ......

None of these are pretty things.

When will you start to stop these things? Tomorrow? Next Year? ????

I totally agree Thomas but I think that sending a few cc of oily water to the recycling centre whilst drilling all over the planet for oil and sending tankers across the globe, occasionally sending our children to fight wars so as to have petrol to put in our playthings is trying to give oneself good conscience and nothing else.

Well, there will always be one who is worse. That would then justify everything.

Let's just get started and try it out.
If we all think so, we can do it.

E.g. I produce 68% of our electricity needs on the roof myself. The sun also heats our hot water and heating. That's a good feeling too.
Of course, this doesn't change the world - but it's a start.

Yes Thomas, you're right. Every little bit helps.
I'm just surprised that using a single seat motorcycle that uses more fuel than a modern car with 5 people on board and pollutes 10 times more probably should warrant your smug attitude towards safeguarding our childrens future because you have a system which retains 0.0000000001% of the polluants emitted by the engine breather.

Not to mention your other motorcycles, and mine which produce plenty of polluants where we could do with 1 vehicle, or even better, a modern public transport system.

It's a discussion I will not get into any further.

Nevertheless, we all have one thing in common, regardless of our attitude towards the topic:
Driving a vintage motorcycle for many years IS environmentally friendly, even if the consumption/pollution is higher than that of a new vehicle.

The resources required for building alternatively several short-lived new motorcycles would be many times higher, than our additional consumption and poorer emissions.
