How to F#@k...........

[redeye]

My owner's manual says to change the fork oil every two years. I was reading on how to change it, (in my new Clymers Vulcan SERVICE manual) & this seems to be a very involved job, dismantling the whole front end of the bike. It seems like a job for the dealer. How long do you go between fork oil changes? What happens if this is not done on time?

My bike is a 2003 FI with 8000 miles. The previous owner only did oil & filter changes every 1000 miles. I'm trying to get caught up on over due maintaince issues.

Thanks -Rich
