I have scanned through my Tiger's owners manual and can see no reference to the quantity or the weiight of the oil in the front forks.
I suspect the weight is 10w but would like this confirmed by an owner with, and who can afford a workshop manual.
Any takers?

I'd like to know, too. My Triumph mechanic said I should try changing (to lighter) fork oil weight before turning to after-market fork springs.

Would,nt have thought that thiner oil will help the front end, I believe that the standard weight is 10w but when i replaced the springs with Hagons they supplied 15w, although I am now led to believe that HAGON SUPPLY 10W now with there new springs for the tiger.

Yes I agree clive955 the oil I feel should be heavier, which might stop the infamous clonking.
I'll try a 15w oil to start with but I need to know the quantity!

Anyone?

At the risk of sounding to simple,when i changed to 15wt,just pured out what was in the legs and replaced with the same amount.

Just remember if you change anything on a brand new bike, your warranty could be affected, seek advice from Triumph in the first instance OK :???:

Don't know if the newer bikes differ that much, but it used to be 682cc of fork oil, the level being 119mm and grade 10w as stock. I use 15w, as recommended by WP, with level still at 119mm. I believe that mixing your own 12.5w oil has good results according to some.

Try this,

Before emptying the old oil out of the fork legs incert a very clean piece of wood or metal to mark the depth, empty and then refill to the mark first made. :-D

Trouble is, that to measure the depth, you have to remove the springs which will drag some oil with it.
I use a big syringe with a strap around it, set at the depth that I want. Then you just fill the leg up and suck out the excess.
The settings I use are :- 13.66W oil (mix 500ml of 15W with 250ml of 10W) filled to 110mm from top of leg fully compressed without the spring.
I find it firm enough to reduce dive on the brakes and still supple enough for decent comfort.

My forks have never clonked, so I can't answer for whether a change in oil makes a difference there. I do have Hagon springs installed, and used 650ml of 10W oil (an air gap of approx 120mm with the fork leg fully extended and the spring installed.

I would have thought that a 120mm air gap without springs would cause the oil to splurge out when fitting the spring.

I did find the forks still slightly soft with 10W oil so changed to a blend of 75% 15W and 25% 10W; this gives a significantly firmer ride, with less dive. I would not want the front end to be any stiffer as it has become noticably more harsh, thus losing one of the Tiger's big plus points: its hovercraft quality ride.
