Changed my front fork seals a few months back , they seemed ok at first /a little on the soft side however I’ve ridden a couple of times since and the forks have gone softer and softer and now they are very springy and bottom out after a wheelie , I used belray oil as reccomended , anyone know where I’ve gone wrong? 

If they are not leaking, just do a measurement and get the correct oil amount in there. At the same time check the spring.

One side is weeping slightly but nothing major , could it be just an issue of not enough oil ? I followed the guideline to collapse the fork and fill enough to leave an air gap so maybe I’ll just have to repeat the process ?

 It is a specific measurement. And on the right side you have to pump it to get all the air out.

Did you bleed out and refill the cartridge per the owners manual?  It is what lineaway is referring to.  It is not that hard to forget if you have not done it lately.  

Thanks for the replies guys I think I’ve solved it , the damper rod had unscrewed itself from the top cap of the fork so basically the damper was just sat in there doing nothing,I threaded it back on and tightened the lock nut underneath then collapsed it and refilled it , seems a lot better now ?
