Just been re-assembling the Showa forks from my 2000 year 315. I followed the manual, bleeding everything as described and filling with the specified quantity of fork oil. The figures I have are:

right fork: 407 cc fork oil to acheive 39mm air gap

left fork: 391 cc fork oil to acheive 97mm air gap

Problem is that the oil level appears to be 20mm+ too low in both cases.

I'm no suspension expert, but I do know that the oil level / air gap measurement is a critical one where a few mm difference will make a big difference. So it is important to get right.

Does anyone know for sure if any of the specifications in the manual are incorrect ?

I have always been told to go by the measurement not the volume of fluid you add.

Yup, oil height. After the valving is covered with sufficient amount of oil, the important part is how much air you have above the oil, not how much oil.

Volume is just to give you an idea....

Thanks Mud and Sherco, that's what I thought too.
