Laverda 750s starting problem

I think so!
The numbers indicate how many times the wire is drawn through a die to reduce the diameter.
So 4 gauge has been 'drawn' more times than 2 gauge - therefore 4 gauge is smaller in diameter!

Simples?

EHH ? well that depends on the size of the die, drawing through twice will not make it smaller :)
Gauges vary enormously for example SWG is different from metric, sometimes Gauges vary in dia depending on material, wires can be gauged on electrical resistance for example, sheet is usually measured by gauge which is a set amount of material hammered out into a foot square and then thickness measured. some wire gauges are simply .5" start dia then reducing by a given % for each smaller gauge.
As has been said thicker wire and thinner wire works well :)

Good picture Craig, i will print that off and cut it out carefully :)

You would have to terminally stupid to keep drawing through the same die over and over  :D
A did say 'a die' and not the same die!

one other fix for the sprag clutch...there is an excellent step by step version on how to fix in this months practical sportbikes..let me know if you want me to scan it and send it to you

Yeah I definitely want that video even though I'm not the guy you're talking to but I still want that video cuz I have the same fucking issue with my laverda

Opps.. I meant go from the smaller 2 gauge to 4 gauge....need more caffeine I guess

The three most common "quick fixes" for the zane bikes are the battery cables, sidestand bypass and stainless oil filter

For the battery cables, Zane bikes came with the 3 battery cables all in 2 gauge, one from the starter motor to the starter solenoid, one from the solenoid to the battery and one from the negative battery terminal to a ground on the engine. Updating from the small two gauge wires to a 4 gauge wire set seems to remove the "ruh-ruh" tough starting issue, which puts less strain on the generator and sprag clutch.

For the sidestand bypass, this is located on the riders right side under the small side panel. Its the square unit and it has a tendancy to fail over time. I can get a simple bypass plug that makes it so the sidestand bypass wont kill the bike but the sidstand bypass warning light will still show inside the tachometer.

The last fix is a simple replacement of the standard oil filter with a stainless unit. As you already know, the Zanes have a reputation of bad cranks but really this is due to an oiling issue. Replacing the standard filter with a larger stainless unit (such as this) helps resolve the oiling issue and avoids the need to worry about the crank issues.

Now Martin what you're trying to say actually is that they came 6 gauge and you're going to replace with 4 gauge because that's what they came with sorry buddy. I'm a journeyman electrician so there you go. I kind of know about my wire sizes... Thanks for the starter actually it works very well by still doesn't start because of the f***ing sprag now.
 
what ever. After replacing the wires on my Formula with thicker ones, changing to 4-brush starter plate and changing the starter gearing, the bike instantly barks into life on the first push of the button (if not the first, it is the second). Much improved to before and comparing the 996 Ducati of a friend of mine (who had the same issue), the Laverda is now a very reliable starter... Fresh gasoline is mandatory though...
