Zane water cooling system refill

Ventodue said:
Be VERY careful about how much you put into that 'header tank'.  Because 'header tank,' it is NOT.

It's an expansion vessel.  You put too much fluid in it to start with, when the radiator gets hot, the expanding coolant will start to fill that tank and, it being under pressure, the tank will split along the seams.  Many people have made this mistake.

Do NOT fill the tank, when cold, above the minimum mark!

thanks for the precious advice.
I serviced my cooling system last year, because of a lack of liquid from the water pump sealings.
For sure I refilled too muck the "nourrice" (why the f they called it this way?) and it started bleeding, when in pressure.

checking it, I noticed some filler in the crack: someone made the same mistake before me!
I ordered a brand new one, and now it's of course ok.

BTW, I still have some drops from the hole under the water pump shaft. I'm afraid I have some scratch on the shaft sealig housing. I have to reassemble it with some liquid sealing to fill it.
 
In 2000 was it, the year Aprilia took over Laverda, we were introduced into the closed Zane factory by an ex employe who had the keys. The Aprilia people looked at us very suspiciously from behind their PCs.

A couple of expansion vases were taken fom the stock.

wow! what an experience!

I was amazed visiting the warehouse of the Laverda spare supplier, last year! so nice to see all the brand new frames and spares, pretending the factory's still alive!

Mmm our engine numbers are 3 out and this one has 19 k - almost certainly it has not had any work done but magnetic plug was free of debris - fingers crossed

I don't want to make you feel bad, but a german forum fellow also did not listen to me when I told him that it is not a question IF the main bearings go bang, it is a question WHEN.

Hi achieved 34.000km I think which is one of the best results for a 2000 spec formula I have seen so far without the mains giving up. The engine was seriously damaged and he gave up and sold the bike.

So - better be safe than sorry...

It's not the first time I listen to this warning..
what bearings are you talking about? the ones on the crankcase or the ones on the connecting rods?

Maybe it's an obviuos question (in that case, I'm sorry!), but I can assure you that nobody in my old italian forum has ever change those bearings..

correct!

I think he should have also something for Breganzes, but I'm not sure..

i'm not sure but i think I saw some brand new 3C crankcases on a shelf, some years ago

Small world.
I've known Giuliano many years. An ex employee of Moto Laverda.

Was pleased to see him again In Breganze last July.

Definately the ones on the rods having had one fail...
 
Im really pleased with my Formula. But it does feel a bit flat, can anyone recommend somewhere I can get it set up for fueling.  Also the low fuel warning needs sorting light is there anyone around the south west (England) that specializes in Zanes ?
 
Terry, I may have a different chip for you to try if you find someone with tuning equipment.
I presume you have tried a replacement fuel level sensor? If not, I have one.

"all right" then.. and what could be done to prevent this damage?

is there any topic where it's explained?

There are two solutions: one, don?t ride your bike and turn it into a coffee table as some have suggested previously (which is a bit drastic) and two, have the engine rebuilt and every conceivable modification/improvement made.
I think there are quite a few threads, just search for Zane engine problems etc.
 
Hi Terry,
If it feels a bit flat then put it on a dyno as it stands , you will have a base to start from.

From there you can make (hopefully ) make adjustments to correct any faults. I believe the ECU were used on Ducati (?) so a dyno shop who have experience of them would be a good starting point.

Double check with Ian Calvert(when he was racing a Zane) but if my memory is correct he once used BSD Performance who he reckons where very good, again I think aren't they once used by one of the monthly mags? Personally if it feels flat I'd refrain from riding it till its been checked.

It could well be the mixture is too weak ,which isn't a big problem to sort. I've done some 650/668 mixtures but not 750 and I know from the manual the 750 has a slightly different adjustment procedure.

I highly recommend dyno time, you need to see what she is doing in real time.

yes, I've found something written by Laverdalothar, about machining a couple of new pins. It could be a very interesting work..

Is there any other workshop making this kind of repairs? I've seen only OCTeam, right now
