Lazy front forks on 1959 g12
The front forks on my matchless g12 1959 have always been on the soft side I have tried different oils but this does not solve the problem. On stripping down the forks last week I find one spring 12 inches long and the other 11.5 inches. I notice in the spares catologue you can still purchase sidecar rated springs which are longer and heavier gauge spring steel, do you think they would solve the lazy fork problem, I am 14 stone and ride solo, yes I need to go on a diet.

Hi Billy, I would definately change the springs to the length specified in your manual.
Wether you go for sidecar rated springs is your choice but both springs must be the same gauge/length.Use oil as recommended in manual.
Cheers, Keith.

Billy,
I had exactly the same problem on my 1956 G80. I bought the sidecar springs from the spares scheme and they work very well (I too have a heavy bone structure!). They add just the right amount of stiffness, without being too harsh.
When you experiment with fork oils, note that the quantity of oil makes a lot more difference than going from one viscosity to another. Try and add a bit of oil to each fork, and you should feel a change towards heavier damping. If you add too much they will can go very hard indeed, but you will find out!

Quite right. I've also found air temperature makes a lot of difference. I changed my fork oil a couple of weeks ago to Motul 20W-30 fork oil. Ride was much more compliant than it had been (I won't tell you what I had had in them). However, now the temperature in the SE UK has dropped 10 deg, they feel much harder again.
