how do i replace fork seal? is it hard? what are the necessary parts and tools?
You asked a similar question on March 18 in the thread you titled oil coming from the forks (http://www.gstwins.com/forum/viewtopic.php?t=7571).
Please review.
The replies included a couple good links to existing threads on the topic. Also, a detailed blow-by-blow from Bob Broussard that I'm sure took a good bit of time and effort to type up. (Much more time and effort than it took me to find it by searching with the phrase "fork seal tools".)
