Re: [St] Fork oil question....

["Lou" <LouJ9@xxxxxxxxxx>]

Karl:

The first number in the oil is viscosity when cold.  As long as it is not 
cold outside, on the Triumph don't worry about the first number as long as 
it is not higher than 20W.  The second number is the effective viscosity 
when warm.  That is your more important number and I would keep it no lower 
than 40 for the Triumph.

Triumph would therefore be fine with 20W-50, 15W-50, 10W-50, 10W-40 etc.

Some mechanics are averse to using oils with a wide disparity in numbers 
e.g. some mech's prefer 20W-40 to 10W-40.  I don't think that concern is 
supported by facts.

Use detergent oil only.

Hissing is not related to need to change fork oil.  If you get fresh fork 
oil, good after market springs, new fork seals (if needed), and a new front 
tire all at once - you will be astounded at how great your bike handles.
