okay so racce tech recomend 30wt fork oil iver never seen anything more than 20wt anywhere does this sound right to you ?

Fork oil viscosity `weights` run up to 30 indeed, some forks (older designs) even use straight 50w engine oil!

cheers bud shall have a look through it all

In a fit of desperation a few years ago, I used a 10/30 two stroke gearbox oil in my FZR400 forks. It worked really well Mind you, that was probably just due to replacing the dirty water that came out with actual oily oil.

Next to Whitham, you look like a man who could use 30 weight

well im only 6,5" and 130kg he is very small though

the forks feel much better with 30wt in them and hagon springs

...or a ventriloquist.

I have now 20wt oil in my forks. And it does his job verry well!
Stock is 485ml in each fork. Now i have added 510ml. This makes it also al lot better.
