    You will find it straight forward with a manual, they list all the specs and torques sizes and amounts plus walkthroughs

    Thanks for that.I think the standard oil is 10w but not quite sure if its best to go 1 thicker.I am still waiting for my seals to arrive anyway. Cheers

    I had a GT and I increased the weight up one. What I thought was most effective was increasing the amount by 5cc. This gave me less dip when I first applied the brake.

    The bike shop reckoned use 15w and fill up with the fork leg fully compressed without the spring in 5 inch from the top.he said top up and move up and down until it becomes stiffer to remove all the air.you probably know all this but just thought I would mention it

    It dives a bit when heavy braking ,and also very heavy on the steering,although I've upt the front tyre pressure to 40 and it does seem better.The reason aswell is I have a leaking fork seal so i thought why not have a play .Just trying make it better lat handling like my gazer I had

    The thing about nominal weights of fork oil is that they vary between manufacturers. If it matters to you then some experimentation in volumes/air gaps and weights will pay off. I am pretty sure Triumph numbers are based on Castrol lubricants.

    You can get the manual online.

    Hi, just to add a fork question to your topic. From the search I did, the showa fork seems not to need any special tool to be disassembled. Can someone confirm?

    I did mine with only a sharp piece of wood around 2 feet long to hold the damper still when I did / undid the bolt. 5cc increase sorted my brake dive, you may find tyre wear and type contribute to turn-in speed/ feel.

    Thanks for your answer. If I understand ok, I just need something to apply a pressure on the damper?
    I usually preload my forks to get a proper feeling. i'll see that later. I'll first change fork oil/seals to start from somewhere
